Windows 10 apps or Store not working for some users

That might be a good plan. I should think a restore point will take you back. Better still is to take a system image, either via Windows or use macrium. An image takes a while depending on how much data but it's re assuring to have. Then you know that you'll be back exactly where you were.

I dont know know if your situation is unique. I struggle to remember my first setup. We have 4 family accounts. Mine as head of household and admin, then 3 family standard accounts. From memory, logging into those after my initial setup did not corrupt my apps or store. But I have had big issues with native apps on the 3 standard accounts breaking subsequently. The pattern as far as I can tell, is I check for updates on my admin account, say one for photos is available. Then I click to update it. Photos completes the update, the app works fine for me and the other user accounts. However, on rare occasions the app update doesn't work as intended. Say I click to update it, then for some reason it gets stuck or fails. So I re-try it. It then completes. I launch the photos app in my user account, it works just fine. However on the other user accounts it may no longer work. So it's Russian roulette. As if the native apps and store tries to update for all user accounts in that one hit and it messes things up if the app update doesn't go smoothly first time. Third party apps such as Facebook do not suffer this because the app is specific to the user account it was installed on. If that makes sense. System restore always fixes this whereupon can re attempt the app updates in the hope that this time it will update first time. It's for this reason I do not allow automatic updates to happen as that way I can keep a close eye on things. I'd hate to think auto app updates happening on the fly in the background could be rendering native apps useless for the other users without me knowing. I would then not be able to count on system restore reliably as I wouldn't easily know when an app went wonky. It is an epic fail that there is no reliable way to repair native apps. That powershell command that I have seen many times cannot be relied upon either as it has unpredictable results and can make things much much worse.

But whatever way we look at this the bottom line is the native apps process is seriously bugged and MS has screwed this right up. Its behaviour cannot be trusted. It's the primary reason I dislike Windows 10 and pine for the days of Windows 7. Every boot of Windows 10 breeds uncertainty as to what might happen. And every check for updates in the store brings dread, sitting in hope that MS has decided not to chuck a native app update down the pipe as I just cannot trust their OS. I get little spare time to use my PC as it is without having to waste time worrying and doing system restores.

i had another laptop with Windows 10 but had such horrible issues with cortana, the store, logging into native apps (among other things). The issues were a bit different to the above so it's another story but it was enough to make me return the laptop to manufacturer for a refund and make my first ever foray into the world of macs.

Deep down I will always prefer Windows but the Windows 10 experience and it's unpredictability and bugs has been hard to take. The MS accounts, native apps and it's attempt to no longer be a proper desktop OS instead acting as some horrible hybrid phone/tablet/desktop OS I'm sure at the root of it all. Maybe in a few years once it matures it might be much better but as a user I have no interest in beta testing or tolerating the early gremlins. Unfortunately there is no getting away from Windows 10, it's being forced in our faces pretty hard by MS and I guess before long certain software/games will no longer run on older Windows so 10 will became a necessity. We can only hope in time MS gets this right. Trouble is they seem hellbent on flooding change, features rather than addressing bugs - i'd rather a reliable OS over constant new builds with new features. More changes brings new bugs ontop of old old bugs that don't necessarily get addressed anytime soon. At the moment it's a stress inducing OS. I do want it to succeed and be a good OS, hopefully one day!

anyway I got side tracked here into a big anti-Windows 10 grumble which I apologise for - sometimes just good to get it off your chest but I hope you find that solution alluded to way back at the start makes things more palatable. I'd be interested to hear how you get on.
