Hello, I regularly defrag the hard drive (1x/mo) and use the windows clean-up tool (weekly). A friend told me to also intall CCleaner to help keep the system operating at peak. I've done that on three of my machines. Seems to work great! Trouble is with one of my machines, when I tried to run disk defragmenter the system seems to get stuck at
defragmenting 3% Moving File _REGISTRY_MACHINE_SOFTWARE
The system does not lock up, as I can choose pause, resume, stop etc... I have tried this three times now and each time it's been hours and there is no activity. The latest ran 14 hrs and stopped at above. Normally, I can barely hear the hard drive working away when the defrag is in process and it's done in 15-20 minutes (if that). I've tried re-booting but no luck getting past this. System seems to be working fine, but can't defrag drive now.
I assume since running CCleaner, it's done something to the registry which is preventing me from running the defrag. Any help or ideas would be appreciated.
