Recs for PC Maintenance System Utility?

[brianosaur]

I am running Vista 64x

Can anyone suggest one or two all around system utility packages that perform PC check-up style functions?

I had used various programs in previous versions of windows that would perform system maintenance such as: check/fix the registry of errors, check/fix the hard drive, clean windows, defrag the registry, defrag the hdd ect. Most of the ones I have wont even install now in in vista - let alone 64x.

I run chkdsk /f occationally, and also use the stupid vista defrag ...but that prog is slow and doesnt always work

I know over the years some software boxes just didnt do what they were supposed to very well, so I was hoping for a rec on a nice package of progs known to work great.

Would start with www.ccleaner.com

I don't use anything other than that. I have no problems with vista defrag either.

My personal favorite, for Vista, is NCleaner
For defragmenting in Vista, I use Aoslogic Disk Defrag

CCleaner for diskcleanups
Diskeeper for defrag
