[Registry Cleaner causing Windows 10 Window Store and store apps to not work]

I spent days and every possible solution trying to find a reason why Windows 10 windows store stopped working after 2 months. I then had a Microsoft Support Engineer tell me that the crash im having with the store is caused by CCleaner Registry Cleaner deleting necessary files.  I hadn't even told him I had CCleaner.  I always back up the registry and even after restoring the the last 5 or so registry backups I still can't get windows store to work. It would not merge the older backups I tried it said it couldn't.  

Every time CCleaner runs, Cortana and the Windows app store disappear until I reboot the machine.

 

I do understand what Nergal says, but a. it isn't advertised like that, and b. which of us is technologically competent to make the decision as to whether to delete something or not?  The whole point of something like CCleaner is that it should be fire and forget.  It sells itself on "Easy to use, one click cleaning so beginners can optimize their computers in seconds".   The paid for version advertises itself as having "Automatic background cleaning".

[2.08 crashes when defragging, but 2.06 does not]

I installed 2.08 following the prompt, and proceeded to defrag my drive. It started OK and I left it to its own devices. When I returned, it had crashed. SO I closed and restarted; same again - lasted half a minute. Must be me, so I did it again, and defraggler crashed again. SO I did a chkdsk, restarted, same again.. SO I rebooted and restarted, same again. Microsoft has by now got a lot of reports from me.

 

OK, so uninstall and reinstall. Same again.

 

So uninstall, install 2.06, works OK and has happily defragged my hard drive.

 

Windows 7, 64 bit. Up to date with all MS updates. I only had one prgram running - defraggler.

[Defraggler suggestions]

C:\System Volume Information\ should be excluded by default and should not count when calculating fragmentation. Lots of users are confused because of this.

Agreed strongly. This was driving me batty yesterday. I could not find out why I am still 18% fragmented and defraggler was moving files around but never changing the one file that was fragmented. When I first ran defraggler it got down to 14% fragmented, but with only that one file it is now up to 18%. It makes no sense whatsoever.

[Vista 64-bit: Defraggler says complete but not true]

Those are System Restore Points. You cannor defrag them. And even if you could it would be useless.

 

So why doesn't defraggler have a note that it will not defrag this? It would save a lot of heartache. It tells me I am 14% fragmented so that would suggest that i need to continue to defragment my drive, but there is only one file fragmented. But 5 minutes later there are 9 files (antivirus program updated).
