Resolved trying to undo win 10

i have a gateway all in one computer, zx4970 and most of my programs don't work so i want to go back to 8.1 but its been more than 30 days.
i tried going through gateway restore manager to go back to factory settings, but this win 10 won't let me do anything. any sug.

 

Have you been to the program/s web site to see if they have W10 compatibility?

need to downgrade, over 30 days after upgrade, no back up of win 8

Have a look here and see if you fall into the category. Neil.
Going back to Windows 7 or Windows 8.1

 

I tried everything, even tried to reformat the hard drive with a boot disk. but it won't even let me do that it goes through the motions then just takes me back to the openening page
of win 10.the says reset didn't work you lost nothing.

 

I don't have a copy of win 8.1 it came with the computer, and I don't have backup copy.
and there is no sticker with the number on it.

 

You fall into the category of the 1st link in my previous Post. As I suggested you may have to visit the program sites for help otherwise you will need to purchase a new licence. Neil.

 

ill try it thank you.

 

With no Key Code? They said that they didn't have one in post #5.

 

just wanted to thank you, gotit installed, no problems. but I did find out what was causing all the problems. seems I had a trogan horse called KOOBFACE.

 

Once again a reminder to ensure your comp is TROUBLE-FREE before any Upgrades are attempted. Neil.
