Remove the Shared Documents folders from My Computer

One of the most annoying things about the new Windows XP user interface is that Microsoft saw fit to provide links to all of the Shared Documents folders on your system, right at the top of the My Computer window. I can't imagine why this would be the default, even in a shared PC environment at home, but what's even more annoying is that you cannot change this behavior through the shell: Those icons are stuck there and you have to live with it.
Until now, that is.
Simply fire up the Registry Editor and navigate to the following key (To open the Registry Editor simply type 'regedit' on Run window): HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ My Computer \ NameSpace \ DelegateFolders
You'll see a sub-key named {59031a47-3f72-44a7-89c5-5595fe6b30ee}. If you delete this, all of the Shared Documents folders (which are normally under the group called "Other Files Stored on This Computer") will be gone.
You do not need to reboot your system to see the change.

Speed Up Windows XP by Keeping the OS mmry

One thing you can do to speed up Windows XP is to make sure that key operating system functions stay in memory. Memory (also called "RAM" for Random Access Memory) is much faster than the hard disk. Perform the following steps to boost your XP computer's performance:
Click the Start button. Click the Run command and type regedit in the Open text box. Click OK. As always, be very careful when editing the Registry. In the Registry Editor, go to the following registry key:HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management Right click the DisablePagingExecutive entry in the right pane of the Registry editor and click Modify. In the Edit DWORD Value dialog box, type the number "1" (without the quotes) in the Value data field. Click OK. Close the Registry Editor and restart the computer.

Speed Up Windows Vista

One very cool feature of Windows Vista – especially for machines not natively equipped with the kind of horsepower to fully enjoy the rich visuals of Windows Presentation Foundation (Avalon) applications is ReadyBoost. ReadyBoost enables you to plug a USB key into your machine and have Windows Vista use it as memory. I hadn’t actually used this myself, but had heard of it long ago. When a reader emailed me asking if this was an urban legend, I decided to check it out for myself and was very impressed with how easy and seamless the process is.
Installing/Configuring the USB Key as Memory
First I took a standard USB 2.0 key (I’ll list the prerequisites shortly) and plugged it into my machine. I’m running Windows Vista Beta 2, Build 5346, but I’m told that this works with the latest CTP made available to beta and TAP members as well as MSDN Subscribers. Upon plugging the USB key into my computer, I was greeted with the standard "AutoPlay" dialog box asking how I wanted to the operating system to treat the USB key. However, with ReadyBoost I get the additional option (circled below in the screen capture) of using the key to "speed up my system".
Once I click the "Speed up my system" option, the Properties dialog box for the device is displayed where I can specify to start/stop ReadyBoost usage of the device and how much space I want used as a memory cache. (Actually, according to one of the Product Specialists here, this space is used more as a flash-based page file than true RAM, but the impact is that the more space you choose here, the more benefit you’ll get in terms of overall system performance.)
(In order to return to this dialog box, open the Computer window, right-click the drive (F: in this case) and select Properties. From there, click the Memory tab (as shown in the previous screen capture and adjust the settings as needed).
For the inquisitive, opening the drive in an Explorer window reveals that ReadyBoost has created a cache file of the specified size.

Restore Missing Windows Update Link

Microsoft has made available to all Windows users, a web site that provides Updates to its Operating Systems. By default, a link is provided in the Start Menu. If for some reason you have removed this link or it has just mysteriously disappeared, then here is a simple method to recover this link to your Start Menu: Here is the address to the Windows Update website: windowsupdate.Microsoft.com On the above link, point your mouse directly over the Windows Update link. While holding your mouse over the link, left-click the link and keep the left button depressed. While continuing to hold the left mouse button down, mouse over the Start Menu and wait a moment for the menu to expand. Once the menu has expanded vertically, continue holding down the left mouse button and mouse over the "All Programs" button. The All Programs menu will also expand. Once the All Programs menu has expanded, slide the mouse pointer up the programs menu until you have chosen a location within the menu for your link to reside (you should see a black horizontal line while you're moving your pointer around in the programs menu). Once you've chosen the location for your link, remove your finger from the left-click button and the link will now pop into place. You can right click the newly placed link and rename it "Windows Update" or just leave it as is. Now, you can left click the link again and hold the left click button depressed while sliding the mouse pointer into the Start Menu area (you should again see a black horizontal line while you're moving your pointer around in the Start Menu). Once you have chosen a location within the Start Menu for your link to reside, just lift your finger from the left-click button and again, the link will pop into place. Congrats! You've just added the Windows Update URL to your Start Menu.
