Vista - Vista SP2 INF error

I have a windows Vista Business Pro 6.0. Have IE8. Got automatic update today of SP2. I tried doing disk cleanup and access was denied. Something about INF error? I am administrator on here, and will I not be able to cleanup my disk space or anything else on here now? Should I uninstall sp2? Help.

Did you elevate command prompt before?
Elevated Command Prompt

No I didn't and don't know what that is. I have clicked on your link and am now printing the instructions. Is this something you have to do with sp2? Nobody could help me with my microphone problems in other forum so hope this works.

No

Unfortunataly cmd.exe in Vista even for Administrators never is run with admin rights if you don't elevate yourself it as this link say.This is normal in Vista.Adressed to using compcln command here you are additional link:SP2 Disk Cleanup Tool

I do not want to cleanup sp1 files and not have it available to delete sp1 and 2. Once a month I do disk cleanup and defrag, and I can do neither of them now. Just meant regular files to get disk space! I followed the instructions and got a black box come up to type a command. What am I to do now?

Type:

cleanmgr.exe

Now I cannot delete browsing or cookies from internet options! Access denied. Tried downloading a free song to iTunes and got: folder locked. access denied. What do I do? Cannot do any tasks on here with my programs!

Try creating new user and see if you can delete browsing.

Also, you could try setting permission access.
