Some virus will disable registry editing.
Symantec makes a utility to assist with this. Download here
Save the file, make sure to Save As, file type “All Files”, and make sure the extension is .inf.

When trying to logoff or reboot Windows XP you receive “Exceeded Profile Storage Space”.
First trying cleaning out your temp files with a program like CCleaner.
If that doesn’t work open notepad and paste the following into it and save as fixprofilepolicy.reg
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"EnableProfileQuota"=-
"ProfileQuotaMessage"=-
"MaxProfileSize"=-
"IncludeRegInProQuota"=-
"WarnUser"=-
"WarnUserTimeout"=-
When doing Save As, choose file type "all", and save as fixprofilepolicy.reg then double click on the file.
To shutdown a remote computer via command line you will need to be logged in as a user that has admin rights on the remote computer.
Microsoft describes the use of the shutdown command here http://support.microsoft.com/kb/317371.
If you follow one of their examples:
shutdown \\support /r
and you get the help page for the shutdown command,
Try this instead
call shutdown /r /f /m \\remotecomputer
Port 80 already in use? But how you ask. If you receive “Unexpected error 0x8ffe2740 occurred” when trying to start your default website in IIS try starting the website on a different port to see if the error occurs again. Try 8080. If it does then you most likely have another process running on port 80.
Are you running Skype? If so open Skype, go to File-> Options -> Connection
Uncheck Use Port 80 as an alternative for incoming connections.
Then start IIS on port 80.
Problem
Initially when shutting down a Windows XP SP3 machine it would freeze on “Saving Settings…” or on “Windows is Shutting Down…”. I didn’t know it was an issue with corrupt updates trying to install until I ran uphclean.exe. A Microsoft utility, User Profile Hive Cleanup
After installing this and running the cleaner from C:\program files\uphclean\uphclean.exe and attempting to shutdown via start > shutdown the machine appeared to hang with the message “Installing Updates 1 of 13″.
Fix
1. Attempt to stop the Windows Update service
net stop wuauserv
If this fails boot to safe mode and follow the rest of the steps
2. Purge the Windows Update cache
cd /d %windir%
rd /s SoftwareDistribution
3. Shutdown successfully. Next reboot you can re download the failed updates.
