Windows 10: PC rebuild and Windows key code

My PC was upgraded from W7 to W10 about a year ago over the internet for free. The PC has now failed and needs a new mother brd and processor etc but will retain the HDs. The repairer has told me that he needs the key code to reactivate W10 in the new set up or he will charge me $180 for a new copy of W10. I have no idea where to get the key code. I have an account with Microsoft for my outlook / 365 software but can’t see anything to do with myW10 or key codes. Do I need a key code?

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.

 

PC rebuild

I had to rebuild an old pc with apps I need that are not current but run on Windows Vista Ultimate. When I try to activate Vista, the MS server says the product key is in use (was activated on the old drive that failed, hence the rebuild). How do I get
the server to allow me to activate my valid Windows Vista Ultimate on this rebuild?
