Hey Caligo,
I updated the software through AMD Adrenaline software itself, "Check for Updates", I had set it to "Recommended Updates Only" a while ago after one of the latest update screwed up settings. Since, I have been on Recommended updates, all updates have been more or less without any issues.
Even though I have a Gaming Laptop, I don't have any games on it I just use it for my work purposes only.
I ran "sfc /scannow" too & even my latest reboot took more than a few mins to boot stuck again on Manufacturer page, which is something new. Usually lappy hangs on "Welcome" screen for maybe 10-20 secs rarely, never on the manufacturers page for more than 5-10 secs.
I raised the issue with Bitdefender too & they wanted me to run one of their log scripts & give them the result, which I did.
I wasn't sure, where the prob lies so raised the issue over here too, along with my AV
