Windows 10: Apps in W10 not working

It is a PC (desktop) .No longer works Start menu, calendar, calculator, MS Edge, Weather - actually they do not open.
I tried some solutions found on the net but did not work either.(This situation arose after 2 months of upgrade)
Eventually, I can reinstall W10 ? (but I do not have product number from initial W7)
Thank you in advance !

W10 Apps Not Working

Every time I try open apps like: Store, Search, Customer Support, Photos, etc. It loads, then goes to a white screen and then closes, I don't know what to do, I been through around 15+ Websites, none of them fixed my problem. Extra Info (If Needed)

Have a look here - as long as your copy of windows 10 is activated with Microsoft the data needed to recognise and activate a clean install is held on Microsoft's servers

 

Hy all, i just mistakely repaired the problem on my PC w10 :3 When i pres windows button all w10 apps were fade out, and they had a little (!) sign in bottom right corner... Now they are all good and work, not shure if this is fix bc i fixed it mistakely :3
1. (windows button)+x
2. system
3. system protection (or something like that, my pc is not on english, and my english is bad so, sorry on that)
4. configure
5. disable protection, apply, delete, continiou, apply, ok, ok
6. (you need to repeat 4,5 for all disk drives you have, if you have only 1 drive go for next step)
7. system protection
8. configure
9. enable protection, apply, ok (for all drives), ok

​Soo, let me know if this helps you :3

 

That's a strange solution (glad it worked for you tho' *Wink )

That entails disabling system protection, deleting restore points, then re-enabling system protection - can't see what that has to do with app security - store apps are governed by Clipsvc - these licences are renewed periodically (lease period can be seen in event log) - sometimes restarting that service it all that is required (applies to digital entitlement as well)
