Windows 10: Why has my profile changed?

I am having a lot of issues with the look and functionality of Windows 10. I've lost my Start menu (when I hit the Windows key it no longer brings up the Start menu, it just shows the desktop); the look of my desktop has changed and when I change between screens the transition is weird. The screens don't transition nicely, they sort of flick off so you can see the desktop then the next screen comes up. It's not pleasant on the eye. This doesn't happen all the time but does happen a lot.


Also, a number of items have lost the X in the right hand corner so you can no longer click the X to close the screen. On some screens you also can't hit Esc to get rid of them. For example, I have my Windows User Account Settings up on screen and there is no way to get it off the screen unless I right mouse click the icon on the Taskbar and hit Close. I can't hit Esc and there is no X.


I have tried other user profiles that I had set up for my children and they are completely different again. They don't have the same issues as far as I can see and they both have the Start menu. I'm not sure what has happened. Do I have a corrupt profile?

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.
