Hi Mikee. I'm Greg, an installation specialist and 10 year Windows MVP here to help you.
That's badly corrupt Windows behavior so I would 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...
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.

Some apps can be reinstalled by doing a search in the Store app once you get it restored. I'll give you everything possible to repair the store. Even if you've tried a step please do it over in this sequence:
See if the fixes here help: https://www.pcworld.com/article/3053099/windows...
Try running the Windows Store apps Troubleshooter at Settings > Update & Security > Troubleshoot.
Try resetting the Store cache: http://www.thewindowsclub.com/reset-windows-sto...
If that fails go to Settings>Apps and highlight Microsoft Store, choose Advanced Settings, then Reset. After it resets, restart PC.
If that fails then reinstall Store. Type CMD in Start Search, right click Command Prompt result to Run as Administrator, copy the following code and paste it into the box using the Edit tools from Box's top left dropdown menu, press Enter:
PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage *WindowsStore*).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"
If these all fail 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...
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 because of the serious and persistent problem with corrupted accounts. Then continue with the other steps to go over your install most thoroughly.
If nothing else works then do a Repair Install, by installing Media Creation Tool and then choosing to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance to the latest version. http://windows.microsoft.com/en-us/windows-10/m...
If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1903 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m....
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
