phixion Posted May 14, 2017 Share Posted May 14, 2017 Not for the first time, CCleaner has decided to do something so that I can no longer boot Windows 10. This has happened on multiple PC's and laptops and seems to be intermittent as to whether or not it completely destroys your Windows 10 install. I've googled and seen others with this problem and still no fix, I'm losing faith. I think I will avoid until a fix is found, this is frustrating.

Moderators Andavari Posted May 14, 2017 Moderators Share Posted May 14, 2017 What exactly are you using in CCleaner, the Advanced section, the registry cleaner, etc? Link to comment Share on other sites More sharing options...
phixion Posted May 14, 2017 Author Share Posted May 14, 2017 Yes, the same settings I've always used. From research it seems to be when you delete the Windows.old folder that bad things can happen. I just can't trust it anymore as when it does happen it means I have to reinstall the entire system. Thankfully I keep important stuff backed up else I'd be extremely annoyed!

Moderators mta Posted May 14, 2017 Moderators Share Posted May 14, 2017 Yes, the same settings I've always used. Sorry you'll have to elaborate, is that a Yes to Advanced settings or a Yes to registry cleaning? What build of WIn10 do you currently have and since there is/was a windows.old folder, when did you update WIn10 and from what build? What version of CC are you using?

phixion Posted May 15, 2017 Author Share Posted May 15, 2017 Yes to advanced settings. Yes to registry cleaning. The CCleaner options I use, are the same I've used since day 1 and they worked fine up until a few months ago. Windows 10 is the latest build, most recently had this problem on a new Dell Laptop, which came preinstalled with Windows 10 although I've had it on my PC a few times too. Current PC install is a fresh install from a Windows 10 USB stick and CCleaner appears to work fine. Laptop is also now using a USB stick install because I had no other option as it failed to boot after running CCleaner. What could be causing this? I've been speaking to a friend who experienced this before me, he did a fresh Windows 10 install, ran updates, rebooted, ran CCleaner and couldn't reboot. Here's some screenshots of my settings: http://imgur.com/a/lwuVl Link to comment Share on other sites More sharing options...
Moderators mta Posted May 15, 2017 Moderators Share Posted May 15, 2017 is it Win10 build 15063.296? if so, my guess is you are using (in this case) a cleanup program that was written before the product that is being cleaned. who knows what changes, for example, MS have made to the registry that CC has no idea on how to handle. but as stated, that is just a guess on my part. did you take the offered backup when cleaning the registry? was the PC not able to start to the Advanced Startup Options screen?

Moderators hazelnut Posted May 15, 2017 Moderators Share Posted May 15, 2017 Deleting the Windows.old folder after updating to creators update should be done by using the Windows built in disk cleanup and not Ccleaner. Also please read this thread https://forum.piriform.com/index.php?showtopic=48181 Support contact https://support.ccleaner.com/s/contact-form?language=en_US&form=general or support@ccleaner.com Link to comment Share on other sites More sharing options...
phixion Posted May 15, 2017 Author Share Posted May 15, 2017 @mta I format regularly, after updating Windows and installing all apps I tend to run CCleaner to clean out the crud left behind then reboot. This works most of the time, only when it doesn't work it can kill my system. All I get is a spinning icon on reboot. I've even attempted to run Windows Repair in order to fix whatever is broken and it won't work. So I'm not sure how making a backup would help if I can't even access Windows to roll back. @hazelnut That explains it, although giving prior warning of this somewhere would be cool... CCleaner seems to be updated regularly, it wouldn't hurt to include a warning if you check Windows.old deletion. I used the Windows 10 USB Tool to reinstall, if I had no access to another PC I'd be in deep trouble with this. https://www.microsoft.com/en-gb/software-download/windows10 if you install with this method, you don't have a Windows.old to worry about. I love this program and have used it for many years. Link to comment Share on other sites More sharing options...
