I'm having a boat load of glitches, I think mostly coming from Cortana (works maybe 3 out of 10 times correctly and sometimes not at all and locks up the windows menu until I kill her in task manager). I spoke to Microsoft who said to do an upgrade that will re-install windows 10 from their website. Second he said I could do a clean install by downloading to a usb but needed a product key. So I called Toshiba and they said to just reset the pc that would reinstall the windows on the partition "clean" (hahahaha, if bloatware is clean) and back to factory specs. The guy at Microsoft said if the problem is with the windows 10 itself it wouldn't help b/c it is the same software. Toshiba says my product key is embedded into the firmware and will only work with the software of windows 10 on my partition. Can anyone here tell me what is what, I don't trust any of these people. The way I see it I have these options and not sure what to do:
1. Try the "reset this pc" option that puts the computer back to when it was new with software on the partition (no product key issue)
2. Try to "upgrade" to the latest windows 10 software (not sure what that means b/c I am up to date?) from microsoft.com.
3. Do a clean install by downloading windows 10 to usb (was told there would be a product key issue from Toshiba and they won't give me mine, said it was proprietary OEM yada yada, whatever).
Please any help/advice/clarification would be helpful.
