Hi Aidan
I am Dave, an Independent Advisor, I will help you with this . . .
If you have actually reset Windows 10, then that is a one-way operation and there is no way to get your data back, it is not like a system restore
Do you use OneDrive or any other Cloud Service to sync your files, or do you have a backup created somewhere, those would be the best hope to restore your personal files, otherwise, a 3rd party recovery utility, but to be honest, they are very hit and miss, when it comes to recovering data after a reset .. .
All software would need to be completely re-installed after a Windows to Reset . . .
