my windows store is not opening,error code 0x80072EE7

I actually just fixed this on my Computer turns out that DNS Client was not working, I opened up services.msc and noticed that the option to turn it on was greyed out and I had to add a reg key to regedit.

First open services.msc either in a command prompt or just type in services in the search bar.

Scroll down to DNS Client and if it is running then this is not your problem, If it is disabled try to turn it on and set it to automatic

If you cannot change it open a command prompt as administrator and type or paste the code below and press enter

Code:

REG add "HKLM\SYSTEM\CurrentControlSet\services\Dnscache" /v Start /t REG_DWORD /d 2 /f

And reboot your computer.

Other thing you might try if that does not work is open a command as administrator and type or paste

Code:

sfc /scannow

and press enter and see if you have any errors.
