Windows 10: Store, start menu, taskbar, and apps like calc not working

I originally wanted to completely disable the UAC as the admin permission messages that popped for almost any/everything i wanted to do were very annoying. I dont remember exactly what i did, but it was something in gpedit or something similar to it. After i did that my windows store app stopped working, and appeared as a blank space in my task bar as it was still pinned there. As the store wasnt working, apps related to it like the calculator disappeared from my pc. They dont appear when i search for them, and links to DL ones from the store dont work either.
I tried the guide here Apps - Reinstall and Re-register in Windows 8 and 10 - Windows 10 Forums and did step 2, but that managed to break powershell and make it disappear as well as disabling my task bar and start menu. I cant right click anything in my task bar, and can only use the start menu's right click menu. I was considering restarting/resetting, but i was hoping someone here would be able to help figure out what i originally did so i can hopefully attempt to fix this

:)

 

Windows 10 Calculator app focus fail

Try to fix calc app in the taskbar in the first position (next to the start button) and use the shortcut key '1' of your keyboard. It is not the ideal solution, but it works.

 

My start menu icons aren't showing up properly!

I have same problem, the start menu is not working. when you click it , nothing happened. Microsoft edge and store icon are missing on the taskbar.

When did you do that ?
If it is not too long ago, and if you do remember the date, do a system restore.
Pick a date BEFORE you did the gpedit as your restore point.

System Restore Windows 10

 

If the above method is out of the question or does not solve the problem, a Repair Install is in order.
Repair Install Windows 10 with an In-place Upgrade

 

Never made any restore points, i always forget about them as i hardly ever needed them when i used win 7.

 

Well, Repair Install is my suggestion. See Post #3.
