Thanks Dear , Its fix my windows 8.

Thank you so so much for this help. It is super easy and effective. Works in no time. Thanks again.

Struggled with Store, Settings, Skydrive etc not working.

Got the Store working and some other apps too using dowloaded troubleshooters from Microsoft, but PC Settings was a no go as well as Skydrive and Photos.

I made a new user using admin tools in control panel and PC Settings was working for this user so I knew it could work and after much more digging around I found this thread here:

It had all of the steps I used to get the Store working again and those that had failed on the pc settings, and then this:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\ImmersiveControlPanel\AppxManifest.xml

Right click the start button and open a command prompt and then paste the above and hit enter.

PC settings working without even needing to reboot, hope this helps someone, paste it forward into other threads you all have no doubt looked at w/o finding this solution.

The above suggestion, though a bit confusing at first, worked perfectly. Open a command prompt (I opened mine as Administrator just in case), copy and paste in the powershell commands above and press enter.  Takes a second and my command line screen turned green during the running of the command but I was able to get right into the PC Settings immediately with no reboot or any other interaction.  Yay!!!  Thanks so much!
