Microsoft apps crashing on startup

[Bastet]

If installing the Store app from the link given didn’t work then you’re looking at a clean install.
A clean install is done by creating installation media on a USB then booting the PC from this USB media & deleting all partitions on the drive (unless you have a data partition then you should leave this). The media will create the partitions it requires.
You will lose all files & programs so you should have a backup of your files & all the installer .exe or installations CDs of your programs.

You can always create a disk image beforehand in case it still doesn’t work.

One question before I do the clean install
Is there a way I can reactivate the Windows product key (I don’t have the code anymore, if there is some way to find it or something?)

[de_Patrick]

After clean install everything works just fine!
Thank you so much for your time and patience during this one
So much time wasted but that doesn’t matter
Love you all and thanks again!
