Defragger SLOW on Vista

I have been renning CCleaner and Defragger on my Compaq AMD Athalon 63 3500+, Win XP SP3 2002, for a long time, no problem Ever.

My son recently down loaded Defragger, on a newer, similar system running Vista. It defrags to 30%, then seems to be working but 12 hours later

is still at 30%. Are there Vista problems, or should I reconfigure ?. I am running rev. 1.10.143, so is he. Please help if you can.

Best Regards, Larry

Hi Larry, and welcome to Piriform.

With Vista, there can be a problem using third party defraggers like Defraggler.

There's a longish discussion on the subject here, and seems relevant from this point in the thread:

Also see the Defraggler documents here:

Hope that helps.
