Restore Microsoft Store application in Windows 10

After multiple attempts, I managed to get Store open by enabling Developer mode (as suggested by one of the posters here) and running the command "Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}" in Powershell. Not sure if is exactly the solution since I've tried different steps suggested by different users in different forums (including uninstalling Store separately) but hey, I am not complaining!

 

Windows.old automatically deleted the day after installing Windows 10

A simple websearch would have given you info quicker than complaining about someone suggesting to upgrade to Windows 10 and something causing the Windows.old to be deleted, which I doubt was caused by Microsoft.
Rebuild System Partition

The second way here we can put forward is to rebuild the system partition. If you don't want to pay a penny to do the lost partition recovery, try this method. Note that this requires you have the Windows installation disk. Now follow the instructions to begin.
Preparatory work:
Boot the computer using the Windows installation media for your running OS. Then on the first installation screen, press SHIFT+F10 to bring up the command prompt.
Now run the following commands at the command prompt.
Step 1:
bootrec /fixmbr
Step 2:
diskpart
select disk 0
list partition
select partition n (n is the Windows OS partition)
active
exit (exit diskpart)
Step 3:
bootrec /fixboot
Step 4:
bootrec /rebuildbcd

 

complain

You will be much better off complaining directly to
the game developer than complaining here, where no one can help you.
