Hi. I done a recent upgrade to Windows 10 from WIndows 8.1 carrying over nothing via the ugprade process and having done so I lost Acer software including care center etc. I have tried alt f10 at boot but that only brings up the ability to reset Windows 10 and I cannot revert back to Windows 8.1 because that option is not there. I have tried freshly installing Windows 10 again to see if there was a glitch with Acer care center downloading but that problem still persists so still no care center. Disk management still seems to show the factory defaults partitions as shown in the image below. I did not opt for any options to wipe the hard drive or any partitions via upgrades, fresh installs. Is there any way I can boot the recovery partition to restore the machine back to factory defaults?
