yeah BIFF same thing happened to me...... My Toughbook Panasonic Military Laptop CF-31 MK4 both are bricked. After being on CCleaner for thousands of years, I was hesitant to install CCLeaner on my Military Laptops, but after installing CCleaner updated all my drivers through Microsoft, I used their CCleaner New Update Driver Program ... said it needed to update 21 drivers, Wuuuuuut ? Seriously
So I opted to use that service after accepting the 14 day trial. It started updating all my 21 drivers I needed, after reset my Supervisor Password was changed. I know my password because I've been using the same password for 20 years, and I know I'm not stupid, my password doesn't work anymore so I know for 1,000 % fact that CCLeaner changed my Supervisor PWD. But CCleaner says no !!!! and after reading your issue regarding your computer being BRICKED. Man what a relief ... so I know I'm not lying or stupid. CCleaner has to believe me now because I have $2K worth of laptops just sitting here BRICKED, it's so upsetting to the point I'm trying to calm myself after these engineers are telling me that's impossible. Well you know in the computer world impossible can be possible. Not all software's are perfect in any which way.
It's upsetting ... my blood is boiling, I know my password and I know CCleaner is responsible for this problem they have with their UPDATE DRIVER program. I hope they fix it .... if they can't at least send me 2 BIOS Chips at $24.00 ea. and I'll fix it myself and replace the BIOS with a non password. Then I'll shut up and not bad mouth CCleaner for their software mistake. Coders aren't perfect.
