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.
No fix yet as it was only reported the other day. Until Piriform comes out with a fix it's recommended that nobody uses CCleaner to remove the Windows.old folder.
If you must remove Windows.old instead only use the built into Windows tool Disk Cleanup to do it which supposedly doesn't damage the OS.
This issue has completely shafted me tonight... two Alienware Alpha machines DOA after removing windows.old with CCleaner. Hoping to locate an easy/quick fix. All of the above hasn't done it. I'll update here if I find anything... (they're not critical machines, so no backups, just a PIA)
I'm not sure to be honest, I likely updated in the last few weeks. It wanted to an update yesterday before I ran it and chose to remove 'Previous Windows Versions'... and everything broke x2.
Anyhow... 5 hours later... My solution was to wipe the SSD and clone these two machines from another good source.
Take aways from this... Have a better backup plan... and sorry team, I won't be reinstalling ccleaner for a while. This was a deep burn of time.
I usually try to get anything from the official site .When is a tricky question . I didn't figure out it was ccclean until I reformated 4 times . I thought it was anything but the cccleaner program until I ran cccleaner then rebooted, thats when I put 2 and 2 together . I got the windows 10 update last night . I installed and rebooted fine . I did (sorry piriform) uninstalled cccleaner . I did run disk clean up and another competitors program after words before shutting down for the night and my PC booted into windows fine .
I hope you guys get this fixed as you all have some fantastic software .
Is this issue fixed now with the latest update? Is it now able to remove the files contained in the "windows.old" folder without any issues?
official word is it was not included in the current version, so until that changes I personally wouldn't be cleaning that area by any other means than the Windows in-built cleaner.
I also realised that registry cleaning in Creators Updated Windows 10 causes another problem. I downloaded the free version and cleaned registry with ccleaner. For some odd reason My touch screen sensors stop functioning after the registry cleaning. The obvious outcome is losing the Rotation Lock option in action center. When I restore the registry backup and reboot it goes back to normal. It seems CCleaner is deleting a registry key which it shoyld not be deleting.
One note which I think may help is I'm using a secondary external monitor. Could it be the case that ccleaner thinks the computer is not using a touch screen and deletes the registry key? I've gone through the deleted items but I couldn't find an obvious key which refers to sensors though.
