Storage Fault

[Bnetq]

Problem is now resolved. I contacted windows support who opened the hidden file path on my behalf as an admin and deleted the non essential folders.

I installed a game on my new HP laptop a few days ago. The laptop is for work, but as it is a new system I fancied seeing what it can do. As the install was taking too long I stopped it midway through, but my disk space did not return.  I restarted the install so that I could fully uninstall the game properly afterwards.

After doing all of this, I am still missing over 50GB of free storage space. A bit of investigation and I've used TreeSize to identify where the 53.8GB file is hiding. It is in the Windows folder, but is a hidden path which I cannot access. The game file seems to have duplicated itself in system files. I don't want to go freely deleting windows files.

I've used disk cleanup and windows storage sense to clear temp and unnecessary files. I've asked on the MS support forum and turned off delivery optimisation (which is what seemed to cause the file to be saved) and cleared unnecessary delivery optimisation files. I tried using a restore point from before the install but it failed due to my anti virus blocking it from accessing files. The restore point I then needed to use was overwritten by the new 'Undo' restore point.

I have exhausted all options it seems. Do I contact MS as the fault was with a download from their Xbox store and with files created via windows software?

Or should I factory reset the computer? I also don't know if I should do this, because I don't have my Windows 10 key as HP set everything up, and will I lose all of the HP software they bundle into the PC?
