Windows 10: Changing my profile on this site and also boot up questions

Received a PM asking me to update my specs to make it easier for people to reply.
I go into my my profile, select system spec, and it just says OS: (in bold) and then W10 (not in bold) on the next line.
No way can this be edited. Ooh err?

Windows 10 (v19041.388)

Now I'm pretty new to W10 and am still learning things l would never have known before.
Things seemed to have changed however.
So let's say my system has crashed and there is no way into it.
How do l now get in to try and get it back from a previous restore point.
In W7 it used to be power on and keep tapping the F8 key, but this no longer works.
And how do l now get into the bios to change the boot up drive.
Regards

:)

 

Lost default photo viewer after profile rebuild

Thanks Brink. I've tried those steps before i started searching Google. After the profile rebuild i don't have the Photo app listed to choose to make it default in either the system settings for default apps or the Open With option.

I can't even find it doing a search. Seems to have been removed somehow with the profile rebuild, which doesn't make sense.

Might be helpful to list what i've done I've done the open with check, the choose default program in the system menu, tried that in device manager default programs also. I've checked the programs and features Turn windows features on/off and it's not listed there (never thought it was but that was a suggestion), searched the MS Store, it's not listed there either.

I don't like playing in the registry unless i have defined steps and haven't found anything for this yet, just the Win7 version like in my OP.

How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
