Removing old files?

[hyong87]

Hey guys, I've just gone from win xp 32 bit to win 7 64 bit via custom install, i'm guessing from what i've read that that's a clean install. After finishing my installation, i realised that my HDD is still filled up with programs from my win xp 32bit and i can still run them, also there's the windows.old stuff. Must I uninstall these programs or can i just delete them, I'm not sure because they can still run. I'm also now confused about which folders are new and which are old. Any advice is greatly appreciated.

Thanks!

My suggestion is that delete those Program Files from the Windows.old file or transfer them to your current Windows Program Files folder (Cut+Paste) and them reinstall them via Repair rather than Install.

I do not understand how programs can still run with a custom install. The windows.old can just be removed, with the clean disc procedure.

Computer>c drive>properties>disc cleanup (including system files). Run several times.
