That's a Dell or OEM variation or feature. Windows 10 factory reset is new, different.
Here's what I use today: https://www.cnet.com/how-to/clean-install-windows-10/
There have been a few that want Dell to re-implement the F8 key but it's uncalled for Windows 10 as the reset is now built in. (It wasn't in prior Windows.)
Hey there. For some reason my dell studio laptop will not let me enter into recovery pressing the F8 key. in file explorer it still shows the recovery partition. i would like to do this to use some of the good software i still have that can not be installed on win 10. I believe it was win 7 before. Any suggestions?
