1. Windows 10
2. Defraggler free downloaded from CCleaner.com
3. It started off at 10% fragmentation, I noticed that C drive is missing from the system defragmenter while it's running. I Stopped the defrag when it was down to 1% fragmentation (reckoning it's good enough and wanting to see if that brings C back into the list on the system defragmenter) but C remains missing there. I've tried rebooting and also clicking into defragment from C drive's context menu.
4. Yes, I can still use defraggler on C
Thank you in advance
