Heed the following from PC Magazines' site:

" Dump file. A dump file stores data from memory during a system crash and can be helpful when diagnosing problems, but like a swap file, it can also expose a lot of sensitive, unencrypted data. To prevent Windows from creating the file, go to Control Panel | System. Click on the Advanced tab and then the Settings button on the Startup and Recovery pane. Set the drop-down menu under Write debugging information to (none).

"Similarly, the debugging program Dr. Watson saves information when applications crash. To disable it, go to HKEY_local_machine\software\Microsoft\WindowsNT\CurrentVersion\ AeDebug and set the Auto string to 0. Then use Windows Explorer to go to Documents and Settings\All Users\Shared Documents\DrWatson. Delete User.dmp and Drwtsn32.log, the insecure logs the program creates."

Heed related advice from 'microsoft' regarding 'Disable Dr.Watson' first before the preceding Dr. Watson advice (go Google search.)

Back up with System Restore, and go ahead. As cautious as I am, I have gladly applied these tweaks, and followed related microsot advice on Dr. Watson.
