Hey guys, I believe what Blackkatt said about registry cleaners. I used to use them all the time on Win7 Pro x64 before I upgraded to Win10 Pro x64.
I know Windows takes care of the registry by itself, and by introducing registry cleaners there's no telling what kind of damage is done to the registry.
Recently I read several articles that said to DO NOT use registry cleaners because of the bugs they may introduce.
I just purchased Microsoft Windows 10 Professional x64 from Microsoft, after I back up all my files and install files for programs I want to keep that I purchased, I plan on doing a clean install of Win10 Pro x64 to see if it clears up some of the problems I've been having.
I ran a registry cleaner about 2 weeks ago and all my EXE files from Microsoft Office 2013 were GONE! Some of the other files were there, but I couldn't run Word, Excel or PowerPoint because the EXE files were missing. I had to reinstall Office 2013.
So, it's gonna be awhile before I back everything up (docs, downloads, purchased files, etc) so it's gonna take me a couple of weeks to back everything up.
I'll let you know how things go when I finish it, and this time NO registry defragments.
I also use BitDefender 2017 and sometimes it blocks suspicious files for no reason. Even after I add them to the trusted list, it still blocks them.
So like Blackkatt said, it could be a myriad of one or more problems causing this. I've also had problems with other programs when installing. Could be registry cleaners or BitDefender. Anyone else use Bitdefender 2017 that has this same problem with Fences 3.03?
