I think a restore would probably be better.
I think this is a wise choice. It will save you a lot of time in the end.

mAL there is no restore point on my home pc either. is this something to do with windows 10, as i havnt used this myware.com browser on my pc
System Restore is disabled by default on a lot of computers using Windows 10, so this is most likely why there is no restore point on your other computer.
one thing i just remembered. We moved home and i no longer can find my old Windows 7 discs or pass code. The windows 10 upgrade was eventually automated by windows 10 because i hadnt chosen an upgrade time, it chose one for me. How would i get windows 10 back on my laptop please
That's not a problem. Fortunately, you don't have to return your computer to Windows 7 in order to reset it.
First step I'd like you to take is to make a backup of your data. Do you have an external hard drive you could use?
Please see the following two links on how to make a backup in Windows 10: Link1 and link2
Let me know if you were able to create a backup or if you encounter any problem. If you were able to create the backup, then we will proceed with the reset.
