About the factory reset and Windows upgrade. Mind you this goes back some but may help.
Bought a new ASUS desktop PC with OEM Windows 8 . Run about a month, then preinstalled programs quit working including Solitaire and other MS games. NO Virus or Malware detected. Then came a free upgrade to Windows 8.1.
10%, 20%, 30%, hang up. Hours upon hours. Just did not happen. This was my first PC I had received no CD, DVD, or USB stick with it.
Now it is a norm. ASUS (Taiwan) dis not help at all only suggested to ship it to Canadian factory to reinstall.
It came back in 3 weeks (Had to Ship it from BC to Ontario factory). Have not realized that the original product key was missing (Factory of course did not have the same OEM installation disk) so came with different Product serial#.
I was able to install Windows 8.1 and subsequently Windows 10.
This Windows upgrade did the same thing on brand nes HDD - 10%, 20% and even all the way up to %92%.
Every time it screwed up a sector, then multiple sectors and in the end it was over 1,500 sectors gone from new HDD. by this nonsence retrials. HDD was crap, and UEFI/Bios crap.
Pro computer shop did declared the MOBO was caput.
Thanks Microsoft.
Later I was able to start from scratch and ended up with Windows 10 Home on my home built computer with new MOBO and HDD.
But because the product key was missing and I had only OEM #, to this day my Windows stay not activated.
No product key, no MTC/Media creation, no back up, no restore, no presonalization, but sure a lots of adds.
My personal advise is avoid factory resets, and unreliable vendors (bought ASUS PC from Staples), and have a bakup OS (LInux Mint) on separate drive (not dual boot).
Best regards to everyone, stay safe
