=====================================
I would run some cleaners & like I say I use them all, suggest you start with CCleaner, RegSeeker & BinMan.
You may need to print this.
I use all these cleaners for W2K/XP, each one specialises in a different area.
Do not be supprised if hundreds of files are found.
Files are either removed to the programs backup or the Recycle Bin ( make sure the Recycle Bin is empty, before using the cleaners, that way you know the files you have removed )
All ( except DustBuster ) allow you to restore them back into the system, either by right clicking on the reg file in the programs folder ( example Regclean & OleClean > Windows Explorer > Unzipped, click on either RegClean or OleClean ) & clicking on Merge.
jv16 PowerTools, RegCleaner & RegSeeker both store in Backup on their main page.
Opening Backup allows you to either Restore or Delete.
EasyCleaner removes to the Recycle Bin & by opening the Recycle Bin, right clicking on the files & clicking Restore.
Has an Update button. Checks you have the latest version & blacklist.
CCleaner, one advantage of this cleaner is, when Issues is clicked & the boxes ticked, it will tell you before you fix ( doing one file at a time ) why the file is there.
Configure the Windows, Applications & Issues panels to suit.
RegScrub
Click on Restore, click the backup to be restored, click on Restore Selected backups.
DustBuster
Very quick, if you want to know what it cleaned, takes about 1 min to clean ( depends on the speed of your comp ) you have about 4 seconds to read the message displayed, when it is finished. Don't use whilst online.
Find Junk Files
I use only > Find Dead Links, which is part of Find Junk Files. Start > Programs.
Backups
Once you are sure they are not needed again ( about one week ) they can be deleted.
=============================
jv16 PowerTools 1.3.0.195, which doesn't expire.

Microsoft's RegClean ( freeware ) very conservative.
By default it puts the 3 files into Windows Temp.
I prefer them in Unzipped.
Right click in an empty space in Unzipped, select Folder & name it RegClean.
Now when you click unzip ( during install ) select the new folder.
To use, you can either open up the folder & doubleclick on RegClean or right click & make a shortcut to your desktop & then put it anywhere you like.

OleClean ( Freeware. I tick all 8 boxes in Options )

RegScrubXP
http://www.majorgeeks.com/download.php?det=2048
http://www.sofotex.com/RegScrubXP-download_L7528.html
Registry Cleaner for Windows XP/2000 Systems (under development is a version that will run in
Windows 98/ME/NT/2000/XP)
I have made it very easy for you to backup the registry prior to using RegScrubXP. This backup process uses Microsoft's reg.exe program. Follow these directions:
Go into the folder where RegScrubXP was installed.
Double-click on these two programs: HKLM.cmd and HKCU.cmd
You should see two files created: HKLM.reg and HKCU.reg
Copy these two files to a safe place.
If you ever need to fully restore your registry back to normal, double-click on HKLM.reg and HKCU.reg to fully restore your registry as it was before you used RegScrubXP.
