That whole “just create a new user account” response is peak support theater

Its unfortunately common when it comes to Windows troubleshooting. "Just create a new user," "Just reinstall the OS," etc. There's an entire suite of tools made by a third party for migrating user profiles between accounts and machines because it is so common.

I spent the first half of my career as a windows admin and I'm glad to be out, working entirely on macOS and Linux now. macOS has its own warts, but I'll take it any day over Windows.
