Windows Login with RFID (Differentiating users)

Projects General Guidance
1

I just completed a very easy and short project to lock/unlock my Windows PC with an RFID card using an Arduino Pro Micro and the RFID-RC522 module.

However, one problem presents when the computer has multiple user accounts, specially in Windows 7.

Since the Pro Micro only sends a few keypresses (enter, then types the password, then enter), when you have multiple user accounts and no one is selected, it becomes useless. Same happens when the incorrect user is selected, it will just try to login with a passwords that's not correct.

So my question is, is there a way to differentiate users (chose one or the other)?

Thanks.

More of a question for a Windows forum but...

Cannot remember what or where the registry keys that need changing are or if this works on windows 10 but you can/could set the PC up so you always had to press CTRL-ALT-DEL to get login prompt and you always had to enter the full username and password.
