[Ran registry fix in CCleaner after Windows 10 update, now computer won't boot]

Had this happen to me also.     Here is what I did . Figured I had a big problem so I was just farting around trying different things.  I tapped the delete key at start up to get into BIOS. OK  got into bios.  Just navigated around bios looking at things for a while  and then hit the  "Esc"  key to exit bios.    10 loaded normally after that. Been fine since. I will not use the registry defrag again until it gets straightened out.  Goes without saying....DO NOT CHANGE ANY SETTINGS IN BIOS.   Navigate around a bit then leave.

 

Good Luck

I uninstalled and reinstalled. Works properly now.     FYI   Windows 10

 

Thanks all for the help

[Defrag not working Windows 10]

Yep not working. I can open the program. When I select defrag it just completes with nothing changed. I started with 6.1GB fragged and ended with the same value 6.1

 

Ideas?

Brilliant.    Derek891 had the home run. Other inputs were solid base hits.

[Leaves 8 gigs unfragged?]

Hello all. New here. Hope everyone is doing fine.

 

I am using Windows 8.1  64bit.  i5 cpu.  Defraggler leaves 8 gig unfragged  every time I run it. Another poster suggested a solution,  I did that, I checked the three boxes in the Advanced tab as recommended.   I also restarted the system. Same issue. Defrages but leaves 8 gigs fragmented.   Suggestions?
