I will try to explain this as easy as I can. I have been using ccleaner for a very long time (free edition). Its been a great program until this issue.
I got the windows 10 creators update and installed it. All worker fine until I ran cccleaner. After running cccleaner cleaner mode (all options checked but wipe hard drive option) and then rebooted my computer, I get the windows logo with the loading circle at bottom of screen. After waiting some time (30 min to 45mins), I rebooted the computer. Then I got a black screen.
After some time trying to find out what happen, I found out that windows lost some/all of its files. Thinking this was a fluke situation, I had to reinstall windows 10.
So yesterday about 3 or 4 days later I got the windows 10 creator update again. DL and installed it. Later that day I ran cccleaner as usual (as I do every day for years before shutting down my pc).
I restarted my pc this morning and guess what? I had the same issue as before.
After some more research of my own I determened that ccclean cleaned some windows file that it should not have.
This seems to be a issue with the windows 10 creators update.
In my case I lost some files I wished I had not lost, but no big issue.But someone might loose much more than me.
My final thought is that cccleaner is removing something in the creators update.
Thanks for a great program. Please respond why this may be happening.
