Alt-PrintScreen will capture the active window to the edit buffer as an image. You can then paste this image into another document.

I've been having problems with Thunderbird (vs. 2.0.0.16, 20080708) being extremely slow reading my IMAP mail from my employers mail server (which is running M$ exchange). I've had this problem for 6-9 months or so. Sometimes it's better than others, but it appears to be extremely slow when I have new messages, or when I look at a folder with new messages in it. I was ready to give up and try (Microsoft Office 2003) Outlook email, but that can be extremely slow as well.

I'm not sure I've found a permanent fix yet. Sometimes it seems that if I open Outlook and have it update all of it's folders, then Thunderbird is able to run fast. But after a while it seemed like that wasn't helping either, and Outlook was always slow. Then our IT helpdesk person suggested that in Outlook, under the Help menu, I do a "detect and repair". That actually seemed to help. Time will tell...

I've found 3 packages that allow you to typeset equations with TeX/LaTeX commands in Powerpoint (and sometimes other MicroSoft formats like Word):
Aurora
TeX4ppt
TeXpoint

Annoyingly, the xcopy command won't preserve the dates of folders. Insteady, use the robocopy command (which comes with Windows XP and later), which can also be used to provide a mirroring capability (and for speed can skip unchanged files).

How to turn off "Windows Messenger service" in Windows XP, which spammers sometimes use to pop up annoying messages:

Control Panel -> Administrative Tools -> Services. Scroll down long alphabetical list to "Messenger" and select it. Then select "stop". Right click "Messenger" and choose properties. Then select disable.

To make Netscape open up a default profile, copy the Netscape shortcut icon on your desktop to a new file, named perhaps "My Netscape". Right click on this new file, click shortcut, and modify the target line to:

"C:\Program Files\Netscape\Communicator\Program\netscape.exe" -P"%USERNAME%"

(note the space before -P but no space after the -P).  This will use the netscape profile with your present Windows2000 username (if it exists).

This works in Windows NT/2000 etc.  In older Windows, you may have to put in a specific profile name instead of %USERNAME%.  If  you want to use a specific username in Windows NT/2000, you will probably want to create a local alternate shortcut to Netscape on your desktop, not the desktop shortcut shared by all users.

WinDiff will compare two files. To use it, go to "Start", "Run", and then open "windiff". (You might have to install it from a Windows Utility folder on a Windows CD, it might not be installed by default.)

To control what programs are run at startup, go to the Start Menu --> Run--> and type in "msconfig". Alternatively, try the $8 Startup Cop Pro utility.

7-Oct-2008: For some reason, when I right click and look at the "New" pop-up menu, there are options for various type sof files to be created but not for a plain .txt text document. I'm running in Windows XP. I tried running the powertools TweakUI utility to turn this on in the Templates section, but a *.txt option didn't exist, and attempts to create it failed. I eventually fixed this problem by doing "start --> run --> cmd" to open up a shell window, and then typing the command "assoc .txt=txtfile". One can see the command that is associated with the file type "txtfile" by typing the command "ftype txtfile".
