Microsoft Store and various apps don't work in Windows 10 version 1903

Check whether Windows is activated at "START, Settings, Update & Security, Activation". I know some features will become unusable, if it is not activated.

Starting with Step 4...

"4) Type msconfig in Start Search box, right click System Configuration Utility to Run as Administrator.  In tabs for Startup (via Task Manager) and Services after ticking the box to Hide all MS Services"

That seems like a cumbersome way to open Task Manager, but I did it.  I took some screenshots to show that there is no checkbox to hide all MS services, but while typing this, I figured out what you meant.  In System Configuration, the general tab has options for Startup but we don't touch those.  The startup tab opens Task Manager.  Just now, I noticed that System Configuration has a separate tab for Services, and that's where there's a checkbox to hide MS services.

That leaves services for a bunch of Dell drivers, my printer, Adobe Acrobat Reader, and some other makers' applications that I use.  However, all of these services and applications survive the upgrade-in-place reinstallation from Windows 10 1903 to Windows 10 1903.  They are all non-Store applications, and they continue to work.  Only Store applications continue to fail.

Now back to Task Manager's Startup tab, they're all associated with my printer and some other makers' applications that I use.  Again, all of these survive the upgrade-in-place reinstallation.  They are all non-Store applications, and they continue to work.  Only Store applications continue to fail.

Looking at the Startup folder by Start - Settings - Applications - Startup, the list is the same as Task Manager displays in its Startup tab, except that this list is almost sorted alphabetically.  (In this almost alphabetical list, all lower case letters sort after all upper case letters, i.e. Z and then a.  I thought Microsoft hated Unix, but here Microsoft likes the way Unix traditionally did sorting.)

"5) In your browsers' Settings, check Add-Ons or Extensions to disable all but Flash and any Reader helper: How To Disable Plugins/Add-Ons/Extensions.  Change the Search to your desired one"

Well besides Flash, I also have Silverlight, a Cisco video codec, uBlock Origin, and Session Manager.  (I used the web for 25 years without an ad blocker, but had to install a minimally intrusive one for malicious ads which take over a browser tab and poison the tab's history before displaying a malicious redirected page, which made it impossible to return to the original desired page which sadly had a malicious advertisement in it.)  (Session Manager stopped working in Firefox but it still works in Waterfox.)  Again, these are all non-Store applications so they continue working after an upgrade-in-place of Windows 10 1903.

"6) Remove any bundled third party security utilities"

Hmm, you want me to remove Malware Bytes.  Pardon my suspicion again, but I don't think Malware Bytes prevents Windows 10's installer from installing Store applications (including the Store itself) while Windows 10's installer is doing an upgrade-in-place of Windows 10 1903.  I have Malware Bytes installed on several other Windows 10 1903 PCs and their Store works.

"7) Download, install, decline trial version, update,  then run full scans with Malwarebytes, the best free on-demand scanner"

Oh, you changed your mind ^_^  But actually my trials expired, and I still don't think that matters.

"8) For problems with apps  Troubleshoot problems with an app - Windows Help"

Interestingly enough I can reset apps which don't display properly in the list, and I can reset the Store itself, but these resets didn't help.

Reinstalling doesn't work because Store itself doesn't work.  Reregistering doesn't work, as described in my original posting.  wsreset doesn't work, as described in my original posting.

"9) Type Maintenance in Start Search box, choose Security and Maintenance, choose Maintenance, then Start Maintenance"

I couldn't find Maintenance that way but only got a troubleshooter for maintenance.  Start - Settings didn't find it either.  But in Control Panel I found it, and started Maintenance.  I wonder if it will show results later.

"10) Type CMD in Start Search, right click Command Prompt to Run As Administrator"

sfc /scannow gives some errors because some applications are in use.  For example text input is in use, because Japanese Windows systems would be unusable without it.  However, this kind of thing works and continues to work after the in-place-upgrade, because these aren't Store applications.

I've done the dism commands a few times but I'll do them again now to report results.

DISM /Online /Cleanup-Image /CheckHealth

No broken components found.  Action completed normally.

DISM /Online /Cleanup-Image /ScanHealth

The component store can be repaired.  Action completed normally.  (In Japanese, this doesn't make it clear if the repairable thing is the Microsoft Store component, or if it's a place where components get stored.)

Dism /Online /Cleanup-Image /RestoreHealth

Repair action completed normally.  Action completed normally.

I look at Start - Settings - Applications and nothing has changed.  I think the Dism command lied when it said that repair action completed normally.

I click Start - Microsoft Store and it does not respond.  Yes, the restorehealth option is as dismal as the rest of it.

"11) If these still won't repair after running 3 times and performance problems persist I would do a Windows 10 Repair Upgrade which is a simple procedure that"

that doesn't work, which is why we have this thread.

Pardon me while I skip a few.

"20) What we're seeing especially in Windows 10 is that everything depends on the quality of the install so if you want to invest in the very best install of all do this gold-standardClean Install Windows 10 which clears the hard drive to get it cleanest..  You will get and keep the best possible install"

Yes, that works, but it takes a few weeks to reinstall applications and repeat the settings of those applications.  That's why I wish there were some other way to get Store and its apps working without deleting my working applications.

Maintenance (step 9) is still running, no result yet.

There is no reinstall option that saves your files and apps besides a Repair Upgrade which is what you just did with Verison 1903. I only suggested that you do a Clean Install so you'd have an install that wouldn't suffer these problems.

 I would try re-registering again as that's the only repair we have directly addressing those Store apps condiition. 

If you want to try to repair it further then go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:  http://answers.microsoft.com/en-us/windows/wiki/windows\_10-performance/windows-10-performance-and-install-integrity/75529fd4-fac7-4653-893a-dd8cd4b4db00

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account.  Then continue with the other steps to go over your install most thoroughly.

"If you want to try to repair the mess then re-register all Store apps from Option One here: http://www.tenforums.com/tutorials/3175-apps-re...."

I tried that before doing an in-place reinstall of Windows 10 1903.

Trying to reregister for an individual user failed because the Windows folder is missing a bunch of subfolders, including the subfolder needed for Microsoft Store.  The Program Files folder does have appropriate subfolders with appxmanifest.xml files but reregistering for all users doesn't work either.

"You're overdue for a Clean Install."

And I'm overdue for spending 2 weeks to reinstall all my applications and settings?  There is a reason why I did an in-place upgrade and kept all files and applications.  I hoped it would install the missing Windows applications while also keeping my other applications intace, but as originally mentioned, it did not.

And think about it.  Why do Windows installers have upgrade options instead of always forcing clean installs?

"Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key here:"

That doesn't give an option to keep existing applications.  Though I guess you already knew that, since you want me to spend 2 weeks reinstalling them.

Hi Norman. I'm Greg, an installation specialist and 10 year Windows MVP here to help you.

If you want to try to repair the mess then re-register all Store apps from Option One here: http://www.tenforums.com/tutorials/3175-apps-re.... Use the Command Prompt at boot if necessary: https://www.tenforums.com/tutorials/2294-advanc...

You're overdue for a Clean Install. Most tech enthusiast wouldn't even run a Factory or Upgrade install because they'd expect endless issues like you're facing with a corrupted install - and this is even more important in Windows 10 where the quality of the install means everything.

Do this gold standard Clean Install following the illustrated steps in this link which compile the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki...

To create Windows 10 Installation Media (if necessary on another PC) install the Media Creation Tool and follow the directions here: http://windows.microsoft.com/en-us/windows-10/m.... Uncheck the box for Recommended Settings to choose the exact version and bit rate for the target PC only.

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key here: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, skip the Product Key screen and choose your licensed version only if offered. On second screen choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof.

You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the linked tutorial. It's a better install than any amount of money could buy and a great learning experience that will make you the master of your PC because you will learn everything that works best and how to apply it with your own hands.

If you have files that aren't backed up you can use the same bootable media to try to rescue your files using this method: http://answers.microsoft.com/en-us/windows/wiki...

I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
