Hi Mrsoft,
In the previous post, the MVP "Robert Aldwinckle" mentions the method to run the command for clearing the Windows Store cache using the Command Prompt (Admin). You may try that by following these steps:
a) Press “Windows Logo” + “Q” keys on the keyboard and type “cmd” in the search box.
b) Right click on the “Command Prompt” icon from the search results and select “Run as administrator”
c) On the command prompt window, type the following command, and then press “Enter”
WSReset.exe
d) This will clear the Store cache and then it opens the Windows Store automatically.
e) You may now close the Command Prompt window.
Now, check if the issue persists. Please get back to us with the result.
