Hi there and welcome
If you just installed windows 10 then you can still return to windows 7.
To access this, open the Start menu and select Settings. Click the “Update & security” icon and select “Recovery.”
You should see a “Go back to Windows 7” option. Click the Get started button to get rid of your Windows 10 install and restore your previous Windows install. Microsoft will ask you why you want to go back. Fill this in and let the recovery complete.
Once done, you will have windows 7 again on the computer
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else If you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
