Modern Apps are the heart of Windows 8, 8.1 and we all knows this. So if these apps didn’t work properly, you’ll probably feel that Microsoft has robbed you. But that is not exactly the matter; variations in the handling of this operating system yields distinctive results.
Most of users still finds third-party apps better for their system and they do try them; as a results the native settings of the Windows 8 system got tweaked by these apps and user have no idea about this. At last, when he comes to built-in Windows Store; he got an error while downloading, installing or updating apps and feels frustrating.
As a primary solution, he tries to reset the app cache (viz. running WSReset.exe command administratively), since most of Windows 8 troubleshooting sites advocates this and me too, he came around this error:
The remote procedure call failed.
Specifically read : “The Remote Procedure Call Failed” While Setting Lock Screen.
According to the screenshot shown above; it clearly shows that Windows can’t simply reset the app cache, but it doesn’t tells us more about why it can’t? Well, a registry workaround can be done to overcome this issue. It worked for us and we hope it will help you too!
