I noticed in a previous version of Windows 10 (1703) that the Store and a few apps were blacked out, so I updated to the latest version 1709, installed all the latest updates today, and everything is working fine except for the fact that the Windows Store has now gone completely AWOL. I've spent hours going through all the solutions posted here and elsewhere to try and reset/refresh/reinstall Windows Store through app repairs, diagnostic repairs, disc scans, registry resets, powershell commands, safe booting, disabling software etc. etc., but every solution fails for the same fundamental reason -- The Windows Store files are simply not there. There is no package for it in the AppData folder. There is no record of it in the appmanifest file. There is no mention of it when I list the apps through powershell. There's nothing to repair or refresh, period. Nada. It's like the required files simply don't exist on this machine at all. And reverting back to the previous version of Windows seems like a non-starter since that was where the problem started.
So my question is this: is there any way using an ISO file on a flash drive or through a download to actually reinstall the relevant files to the Windows system on my machine without resetting the entire Windows installation? Or is there a way to find out whether the relevant files do actually exist somewhere but just aren't being seen by the system?
Everything else on the machine is fine, and all the Windows apps currently installed work fine, so I DO NOT want to reset or reinstall the entire windows installation. It would be far too much of a hassle to reinstall/reconfigure/customize all the software to set up the machine all over again with no guarantee I won't run into other problems along the way.
Surely there's a way to just reinstall the Windows Store. If not then I'll just live happily without it and continue to be utterly baffled how such a basic piece of software can't be designed to be independent of an OS.
EDIT: I just set up a new administrator account and when I signed in to it the Store app was there and working fine. So clearly it does exist somewhere on the machine. How do I get it back into the other administrator user account? Or do I have to transfer everything from the old account to the new one?
