Yvi, I wish I had read your message before buying Pro in August 2023. I at the very least would have created a Windows 10 Restore Point, as I foolishly assumed the CCleaner Pro had a go back feature. Driver updater has destroyed my computer, for all practical purposes. Half the time on boot, I get a blue screen ("Please wait while we gather information to ignore.") Otherwise, BSOD's are unpredictable at any time. Especially if I happen to leave the computer on overnight. It's November now, but after several Windows 10 updates (my PC is not W11 compatible), it's still totally unreliable. What's more, I have auto renew turned on, although I don't remember opting for that, and I can't find a place to turn it off, so next August I'll have to contest a charge on my credit card. I've used CCleaner free version off and on for years. Pro is a huge disappointment. Yvi, I wish you the best, but I think you're worse off than I am. I would get a USB external hard drive holder and copy all my data to another computer, then start over with a new Windows install. Be sure you have all your user names, program installation keys, etc.
