Is the B450 Gaming K4 ..........

....... capable of running Windows 11?

Hi guys. Please take it easy on this old guy!

I keep running the Windows PC Health Check app and it always comesback with "This PC must support Secure Boot".
Everything else is green ticks.
If the MB is capable then what areas should I be looking at? If it isn't OK then ????

I've been around PC's since the original IBM PC that didn't even keep date/time between boot-ups! But, this UEFI thingy is a little too much for my aging brain ATM.

Updated to Windows 11 on the 2nd November.
It all went smoothly and started well. However, after a few hours problems started with my Sculpt mouse not responding. A wired mouse did work.
I still am not sure what cured it but I did learn to not reboot the machine just because it looked like it was dead/dying!
In the end, after every reboot/restart, I left the machine to sort itself out and it did.
It seems that when it hung on the boot screen it may have been doing something else. It always came back eventually and now it is running very smoothly.
All thoughts of going back to Windows 10 within the first 10 days have evaporated!
