Microsoft plans to release an R2 edition of Windows Server 2008 in 2009 or 2010. Here are the key features of the R2 release that you need to know.

—————————————————————————————————————

When Windows Server 2008 R2 is released in 2009 or 2010 (that is the current projected timeframe), there will be some important features about this release. The most prominent is that Windows Server 2008 will solely be an x64 platform with the R2 release. This will make the upgrade to x64 platforms not really a surprise, as all current server class hardware is capable of 64-bit computing. There is one last window of time to get a 2008 release of Windows still on generic brand for cialis a 32-bit platform before R2 is released, so do it now for those difficult applications that don’t seem to play well on x64 platforms.

Beyond the processor changes, here are the other important features of the R2 release of Windows Server 2008:

Hyper-V improvements: The Hyper-V is planned to offer Live Migration as an improvement to the initial release of Quick Migration; Hyper-V will measure the migration time in milliseconds. This will be a solid point in the case for Hyper-V compared to VMware’s ESX or other hypervisor platforms. Hyper-V will also include support for additional processors and Second Level Translation (SLAT).

PowerShell 2.0: PowerShell 2.0 has been out in a beta release and Customer Technology Preview capacity, but it will be fully baked into Windows Server 2008 R2 upon its release. PowerShell 2.0 includes over 240 new commands, as well as a graphical user interface. Further, PowerShell will be able to be installed on Windows Server Core.

Core Parking: This feature of Windows Server 2008 will constantly assess the amount of processing across systems with multiple cores, and under certain configurations, suspend new work being sent to the cores. Then with the core idle, it can be sent to a sleep mode and reduce the overall power consumption of the system.

All of these new features will be welcome and add great functionality to the Windows Server admin. The removal of x86 support is not entirely a surprise, but the process needs to be set in motion now for how to address any legacy applications.

The other evening my wife was working on her Windows Vista laptop and encountered an unexpected result. She double-clicked on a .PNG image file and up popped the QuickTime PictureViewer. It displayed the .PNG image perfectly, but she had been expecting the image to be displayed by Windows Photo Gallery, like it always has in the past. Claiming that she didn’t have any idea how such a thing could happen, she asked me to fix it.

I knew right away what had happened. She had recently installed Apple QuickTime to view a movie that a friend had sent to her and must have clicked Yes when the installation procedure prompted her to alter the default programs. As such, QuickTime had taken over all the default graphic file associations. Fortunately, my assumption that it would be an easy fix was indeed true; however, I decided to take the procedure one step further and remove QuickTime from the Open With list by using a quick Registry edit.

In this edition of the Windows Vista Report, I’ll show you how to clear out Vista’s Open With list.

Using default programs

As I began my investigation, the first place I looked was in the Default Programs tool. To launch it, just type Default in the Start Search box on the Start menu and press [Enter]. When you launch the Default Programs tool, shown in Figure A, you’ll see that there are four links that allow you to configure how Windows Vista works with programs:

Figure A

The Default Programs tool provides you with four different ways to configure your default program options.

For this type of investigation, I selected the file type association option — Associate a File Type or Protocol with a Program. I then scrolled through the list of file types until I located .PNG, as shown in Figure B. As you can see, the .PNG file type is associated with QuickTime PictureViewer.

Figure B

You can see that the .PNG file type is associated with QuickTime PictureViewer.

To reset the file type association back to Windows Photo Gallery, I selected the Change Program button. When I did, the Open With dialog box displayed. At this point, all I had to do was choose the Always Use the Selected Program to Open This Kind of File check box and select Windows Photo Gallery from the list, as shown in Figure C. To complete the operation, I just clicked the OK button.

Figure C

Using the Open With dialog box, you can easily reset the default program that you want to open a particular file type.

Testing the result

I then returned to Windows Explorer, double-clicked a .PNG file, and watched Windows Photo Gallery pop up. However, when I right-clicked on a .PNG file and accessed the Open With submenu, I discovered that PictureViewer was still linked to the .PNG file type even though it wasn’t set as the default program, as shown in Figure D.

Figure D

The QuickTime PictureViewer was still linked to the .PNG file type even though it wasn’t set as the default program any longer.

Now, I am not totally against Apple (even though I’m a PC guy), but I was annoyed that the program had taken over the .PNG file type and so I really wanted to remove all traces of it.

Investigating the Registry

Doing a bit of research on Vista’s Registry structure, I discovered that there are five registry keys that have the potential to control the list of programs that display on the Open With submenu:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\FileExts\.xxx\OpenWithList

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\FileExts\.xxx \OpenWithProgIDs

HKEY_CLASSES_ROOT\.xxx\ OpenWithList

HKEY_CLASSES_ROOT\.xxx\ OpenWithProgIDs

HKEY_CLASSES_ROOT\SystemFileAssociations \PType\OpenWithList

Where .xxx is the file extension you are concerned with and PType for a file extension could be audio, image, system, text, or video.

In my case, I found that the link between the QuickTime PictureViewer and the Open With submenu was located in the HKEY_CLASSES_ROOT\.png\ OpenWithProgIDs registry key, as shown in Figure E.

Figure E

The link between the QuickTime PictureViewer and the Open With submenu, was located in the HKEY_CLASSES_ROOT\.png\ OpenWithProgIDs registry key.

After deleting the QuickTime.png Binary Value from the Registry, the QuickTime PictureViewer disappeared from the Open With submenu. (Keep in mind that whenever you delve into the Registry, you are potentially playing with fire. So make sure that you have a recent backup.)

In most cases, you’ll find the item that you want to remove from the Open With submenu in the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer \FileExts\.xxx\OpenWithList registry key as a String Value.

For example, I later went to that registry key to remove Windows Movie Maker from the Open With submenu. In that case, I had to delete the free cialis pills moviemk.exe String Value and the MRUList String Value, shown in Figure F. The reason is that while the moviemk.exe String Value represented the actual application link, the MRUList String Value contains the actual list.

Figure F

In some cases you may have to delete more than one registry key.

If you have created a favorite desktop theme and you work on more than one Microsoft Windows XP computer, you may have considered recreating that theme on your other computers. However, manually recreating the desktop theme can be a tricky and time-consuming operation. Here’s how you can easily copy your favorite desktop theme from one Windows XP computer to another.

This blog post is also available in PDF format in a TechRepublic download.

Steps

There is one caveat to this approach — if part of your theme involves wallpaper you created or other graphical elements unique to that particular PC, those elements will have to be copied over along with the .theme file.

Note: This tip applies to both Windows XP Home and Windows XP Professional.

Even if you’re happy with the Linux desktop you currently use, you might want to check out some alternatives to see what you could be missing. Jack Wallen highlights 10 of the best desktops and explains what makes them stand out.

If you know Linux, you know there are tons of options on every level. To some, this might seem overwhelming at first. To others, it’s all about possibility. The desktop is certainly not without options. In fact, the Linux desktop might very well be the area where there are the most options. But for a lot of users, desktop selection doesn’t usually go beyond KDE or GNOME. With this article, I hope to help the average Linux user get beyond the standard fare.

Note: This information is also available as a PDF download.

#1: Enlightenment

I have to confess I put this at the top of the list because it is my favorite Linux desktop. This desktop is all about being full of eye candy, while at the same time being lightweight and fast. Enlightenment was created by Carston Haitzler (Raster) in 1996. He created Enlightenment to be a lightweight window manager that didn’t lack style. He succeeded (and then some).

Currently, Enlightenment is enjoying two releases: E16 and DR17. E16 is the current stable release and DR17 is the development release. The two releases are very different from one another. DR16 takes a far more minimalist approach to the desktop than DR17 does. Without Panels and Icons, the DR16 desktop is made up of three mouse menus (one for each button), an Iconbox (where windows are Iconified — or minimized), a Pager (to switch between desktops), and  the Dragbar (which allows you to have desktops layered on top of one another.)

The DR17 release removes the Iconbox and the Pager and adds Shelves, which are Panels that house application launchers, pagers, clocks, etc. Even with the creation of a more standard desktop, DR17 retains its uniqueness as well as its speed. If you’re looking to give DR16 a try, you can install it via the standard Linux installation methods. Your best bet for DR17 is to give the gOS Rocket or the EliveCD distributions a try. And you should… it’s that cool.

#2: AfterStep

This is another of my favorite Linux desktops. Or at least it was back in early days of Linux. This desktop attracted me because it was one of the first (back around 1998) to use transparency. AfterStep was actually a fork of FVWM rebuilt to resemble the NeXTSTEP desktop. Like FVWM, AfterStep is light, quick, and can be as minimalist (or not) as you like. The main features of AfterStep are a mouse menu, Pager, Wharf (a dock-like applet), and the Winlist (a panel showing active applications). AfterStep is highly configurable via flat text files (so configuration requires getting to know the layout of configuration files.)

Currently AfterStep is enjoying the 2.2.8 release and is headed up by Sasha Vasko. One of the best aspects of AfterStep is the ability to granularly configure the look and feel. From timing of auto-raising windows to placement of titlebars (titlebars can be placed along a horizontal or vertical plane), AfterStep can be configured to a much higher level than most other window managers. You can install AfterStep your usual way. For example, in Mandriva, run the command urpmi AfterStep to install.

#3: Fluxbox

Fluxbox is probably one of the lightest of the lightweight window managers for Linux. It’s lightening fast and incredibly stable. Fluxbox shines in bringing new life to old hardware. And Fluxbox is a gift for those who prefer a minimalist approach to the desktop. Fluxbox is a fork of the Blackbox window manager and was created out of a need to add more features to Blackbox.

The Fluxbox desktop contains a mouse menu, a toolbar, and the Slit. The Slit is a small dock where self-contained applets reside. All basic configurations are handled via flat text configuration files. This manual configuration includes everything from the theme to the menu. To give you an idea of the size of the Fluxbox window manager, the rpm installation file is 1,196 KB. To put this into perspective, the KDE 4 install base is 644.2 MB.

Installing Fluxbox is simple. You can either search for Fluxbox in your graphical installation application (such as Synaptic or Yumex) or you can install via command line (for example: urpmi fluxbox in Mandriva.) If you’re not into installing on your own, you can try the Ubuntu-based distribution, dedicated to Fluxbox, aptly named Fluxbuntu.

#4: XFCE

XFCE is quietly gaining ground on the Linux desktop with help from Zonbu, Mythbuntu, Slackware, and Gentoo. It’s another lightweight desktop that has a more traditional desktop approach, with icons, panels, start menus, and system trays. The XFCE desktop is far less configurable than many of its peers. XFCE was created to be very modular so you can install as much or as little as you want. XFCE is also separated into applications: XFWM (the XFCE window manager), Xfmedia (the XFCE media player), Orage (the XFCE calendaring application), and Thunar (the file management tool). It is interesting to note that Thunar is also now the file manager for Enlightenment DR17.

Installing XFCE is as simple as running urpmi xfce (in Mandriva) or opening up your graphical installation tool and searching for XFCE. If installing isn’t for you, you can download a number of distributions (Gentoo and Slackware for example.) The Mythbuntu Media Center distribution also relies on XFCE for a desktop.

#5: Compiz/Compiz Fusion

When you talk Compiz, you’re talking full-blown, eye-popping 3D desktop goodness. Compiz/Compiz Fusion (they are actually two different projects) is the one desktop to install when 1) you have the hardware for it and 2) you REALLY want to impress your friends and family. Compiz is the original 3D Linux desktop. Compiz Fusion is a merging of Compiz and the now-defunct Beryl Project. Both of these projects mimic some of the features of Apple’s cialis wiki OS X but take them to new places.

One of the most amazing features of Compiz and Compiz Fusion is the Cube. The Cube takes the flat Linux pager metaphor (the ability to have multiple desktops) and folds the desktops into a three dimensional cube. With a click of the middle mouse button the desktop cube zooms out and you can rotate the cube to the cube face you want to work on. Add to this the ability to make the cube (and everything on the desktop) translucent and you have a very impressive desktop.

Installing Compiz isn’t for the faint of heart. It requires a number of pieces to be put together, a video card that supports AIGLX, and some patience. But the time and effort are very much rewarded with one of the coolest desktops to date. If you don’t want to take the time to install, you can give the latest Mandriva or the latest OpenSuSE a go. With the right hardware, you should have a working 3D desktop upon installation.

#6: IceWM

The developers of IceWM are proud of the fact that this lightweight window manager shares absolutely no code with any other window manager (written completely in C++). IceWM can be made compliant with GNOME and can use Imlib for graphics support. IceWM is a fairly straightforward window manager with few frills. The desktop is a panel, a start menu, a system tray, and a pager, and that’s it. IceWM is as configurable as any standard window manager but doesn’t boast the eye candy that Enlightenment or AfterStep does. But unlike Enlightenment DR16, IceWM does have a graphical control center for configurations. IceWM is easily installed via the command like (for example yum install icewm in Fedora).

#7: Windowmaker

Another NeXT-based window manager, Windowmaker took what NeXT did right and did not add FVWM on top. Windowmaker is yet another lightweight, super-fast, highly stable Linux window manager. It takes a minimalist approach but does support most image formats, and it has sliding application menus that can be torn off and pinned. (You can break off a submenu and anchor it to the desktop, leaving it open until you manually close it.) All configuration changes happen in real time. Windowmaker does have a dock where applications can be launched, but it’s not the shadowed, animated dock found in OS X. Windowmaker can be installed via command line, as in urpmi windowmaker in Mandriva, or it can be found in the package administration tools, such as Synaptic.

#8: Metacity

For one brief period, Metacity was the window manager used in the GNOME desktop. Eventually, Metacity broke out on its own. Created by Havoc Pennington (of Red Hat), Metacity uses the GTK+2 toolkit. Pennington has described Metacity as “intentionally boring” even without a logo. Metacity does not include numerous features. Instead, it glaringly boasts “good defaults.” One would describe Metacity as a typical old school UNIX-like window manager. In fact, it’s clean to the point of being almost sterile. But that doesn’t mean it is without merit.

Metacity is lightweight and fast. It is also very much a *NIX window manager, in that it can be installed in nearly all *NIX operating systems. Many distributions (such as Mandriva) install Metacity by default. If Metacity is not installed by default, it can be installed by command (such as yum install metacity) or it can be found in the package administration tool.

#9: FVWM

FVWM was, at one time, the dominant window manager for the Linux operating system. In fact, my first exposure to Linux was the FVWM window manager, and I distinctly remember how like Windows 98 it was — though not as “clean.” FVWM has an interesting history. Robert Nation was the creator back in 1993. He was tired of the limitations of one of the only UNIX window managers, TWM, during his work with the DoD. Nation had already created the rxvt terminal emulator and decided to bundle FVWM with a release of rxvt. He handed FVWM over to another developer a year after its release.

The current version of FVWM is 2.4.20, but interestingly enough, Nation’s last release, 1.24r, will still compile and run on modern Linux distributions. FVWM has a number of derivatives, including AfterStep, Enlightenment, and Windowmaker. To install FVWM, just run apt-get install fvwm and accept the dependencies.

#10: CDE

CDE isn’t really a Linux desktop, but it deserves mention because it heavily influenced so many Linux desktops. CDE (Common Desktop Environment) was created by a collaboration between Sunsoft, HP, IBM, and USL (a collaboration called The Open Group) in 1993. This new desktop was based on HP Visual User Environment and was derived from the Motif Window Manager. For a long period, CDE was the standard UNIX desktop environment. But in 2001, it was briefly phased out in favor of GNOME (until GNOME’s instability caused the return of CDE).

CDE is a fairly standard desktop consisting of a panel and start menu. Its biggest downfall is its antiquated UNIX-like look, lack of anti-alias font support, and confusing configuration. CDE is primarily a Solaris desktop but will install on AIX and HP-UX.

A world of options

And there you have it: 10 Linux desktops (well, nine, really, plus one UNIX) that are all very different, very usable, and very available. You may be happy with your current desktop, but if you really are a fan of Linux, you owe it to yourself to try out one or more of the ones described here. There are plenty more Linux desktops; but these are the best alternatives. Give them a try and report back here to let us know your favorite.

I don't know about you, but I've been dealing with a very frustrating issue with Windows Vista on my notebook computer lately. Here's what happened: I put the computer into sleep mode, closed the lid and then unplugged the network cable. But just a few moments later, the computer woke back up! It happened several times and typically, it did it when my computer was already in my laptop bag, so I didn't notice it until I got to my destination and the battery was nearly dead. What a nightmare!

As it turns out, there's a very easy fix for this problem! All you have to do is disable the "Wake on LAN" feature in Vista. Essentially, the computer is set to automatically wake up from network traffic, which seems to include pulling out the network cable.

To change the setting, type "Device Manager" into the Start menu search box and then browse through the Network Adapters section until you find your network adapter. In this case, mine is "Broadcom NetXtreme Gigabit Ethernet."

Right click on your network adapter and choose cialis review Properties from the menu. In the resulting dialogue box, click on the Power Management tab.

Next, uncheck the box next to "Allow this device to wake the computer" and the problem will be solved! You'll also notice there's a warning about having the option enabled in the first place. I hope this tip helps you!
