My Windows Installer folder (C:\Windows\installer) folder is taking up 20.6 gigs of space and counting. I think this is what's causing my computer to gradually lose free space. I've done some research on the internet, but I never really found anything useful pertaining to Windows XP and Microsoft Office 2007 (which is what I'm running). I'm not sure what files I can delete in that folder. I think the update files in that folder are duplicating themselves somehow so there's a bunch of duplicate MPS files. I think this problem might have something to do with my Microsoft Office updates. I'm not sure what to do or what files I can delete so that I can clean up this folder without harming/affecting the operating system. Can someone please help me out?
I initially ran the program 'TreeSize' to see what was taking up all the free space; my Windows Installer folder is taking up all of my free space. So my son ran 'TreeSize' on his computer and his Windows Installer folder was taking up less than a gig of space.
Thank you for the time you took to read my problem.
