I seem to be having an issue with opening the Windows Store app
I have tried Google search repairs to no avail.
Reset SP4 and it worked once again.
However, a few days later and it is not working again
sorry, should have explained. I did a system reset (reset all setting but keep files)
I have also tried the wsreset
in addition: when I click the "blank" icon where the store should be. I can see in task manager that "Cortana Background Task Host" opens and then closes again. But Store still does not run...
I'm guessing you have double checked that you have all the MS updates. Also that you have a local account as well as a Microsoft account.
I would backup all the data that isn't in the cloud and just do a full reset. You'll need to reinstall your apps but if it's still not right after that there may be something going on that befuddles me. It doesn't sound hardware related but I would have thought what you have done would have solved the problem. Is there anything else not working besides the Store app.
