I had run the cleaner once before, for temp files only, but I had never run the registry cleanup and at the time of this happening, the only thing running was the System Tray icon (the monitor?). But you're right, the fact that it crashed so hard is too dangerous. Next time, I might lose the OS altogether. I can live without the tool.

Yea, thanks, but no thanks.

Sure, there could be a conflict, but I CCleaner is definitely what was crashing it, as the machine would not stay up for 5 minutes until I removed it and FYI, I was not actually using CCleaner, that's just from the part that loads with the System Tray. I tried using WinDbg, but it says the memory.dmp file is corrupt now - after one crash, it basically gave me the same results (something like "Probably caused by win32kbase.sys). It's too risky. I'm not trying it again. Corrupted a bunch of system files and wouldn't even boot at times. I just wanted report the problem, but unless someone reports it is found and fixed, I won't use it. I have never seen a non-hardware related crash this bad before. I just know I was losing a hard drive or power supply maybe even motherboard (video flickering, even a strange crackling noise).

Ok, fine, but that is not addressing this serious issue that I had last night.

Since I posted this on Facebook, I've had one other person tell me that after running CCleaner on Windows 10, they had to completely reinstall Windows. Luckily, removing CCleaner solved my problem (I did runn sfc /scannow). I'm a professional and all Chocolatey does is install the application, using the native installer, with a PowerShell script. No way that it could cause this issue - this is some kind of serious memory leak. Bad enough, that on 2 occasions last night my machine powered off - not a reboot, but shut all the way down completely. This is also not the first time for to occur in CC's history: http://forum.piriform.com/?showtopic=33996

I installed this today and when suddenly my machine crashed...hard. Like I was sure it was loss of a hard drive, video card, something. I finally got it back up long enough to see what was going on and the only thing I could find is sometimes, right before it crashed, I would get a close programs due to low memory and the only thing listed was CCleaner. I've had updated to the new version (5.15, via Chocolatey https://chocolatey.org/packages/ccleaner) today. I uninstalled CCleaner, no more crashing. I was getting a BSOD message of "System_Service_Exception win32kbase.sys".
