So, I’m trying to clean up every non-essential program from my computer to free up space. When I open my hard drive through "My Computer", my Windows file is using over 35 gigs of space. When I open the actual Windows folder and combine all the files (including Hidden), they total around 4 gigs of space, which I think isn’t too far off the normal mark. So it would seem that Windows XP is just stealing squirreling away about 30 gigs of needed disc space.

Here’s what I’ve tried so far:

– Removing all alloted space for Recycle Bin
– Completely turning off System Restore options
– Running CCleaner, Wise Disk/Registry Cleaner, and the regular old Disk Cleanup and Disk Defragmenter.
– Clearing out all cookies, temp folders, and logs.

I’m not sure how to thank those who answer, so I’ll do it ahead of time. THANK YOU… if anyone has any ideas, please let me know.
Ok, thanks guys for responding. I’ll try your suggestions. Just to be clear, I’m opening My Computer, then clicking once on my hard drive. It tells me I have 45 gigs of used space, when I then open my hard drive, I right click on the Windows folder, then click Properties. The folder properties display tells me 35 gigs are being used. When I then open the Windows folder and select all the contents, they only total to about 4 gigs.

Windows XP Product key?

MY computer recently crashed and went to a repairguy. ( A friend of my dad fixed it) Now since the computer crashed he put a new hardrive and basicly most of the files are missing. So i was trying to reinstal Mcafee and IT said my software product(windows) is out of date and need to be updated. So i go on windows updater and it says my product is not genuine.
I go on my computer and i click properties and i see the Registered to: section got changed and had the repair guys name. SO now the PRODUCT KEY IS CHANGE AND WIndows thinks its now a fonny any ideas on what to do
