Windows 10: How can I find and disable hacker's access to my account?

What seems to be happening is someone has gained administrative access to my windows / Xbox email login. They have complete control of every system I run and what they do is promptly dismantle system security in bios and windows. Creating group policy as administrator above me disabling windows defender updates and locking me from access. They then change the folder structure and partitions. I have a new computer I'm trying to get online but stupidly used the same account. I will create another and try again. Any security suggestions would be appreciated. Thanks, mike

Can a hacker access all user accounts?

If you were hacked then it would initially mean the user account you were using at the time had been hacked. Only those areas of the computer that that user account had access to would be accessible to the hacker.
- If the hacked user account was a Standard user account then only that user account's folders would be accessible.
- If the hacked user account was an Admin user account then all other user accounts' folders would also be accessible.

Naturally, having gained a foothold the hacker would attempt to go further and infiltrate all other areas of the computer but that would be a separate task.

Can a hacker access all user accounts?

Hello everyone!

As you know, Windows allows you to set up multiple user accounts on one computer. If I got hacked, can the hacker access all user accounts, or just the one I was using at the time I was hacked?

Thanks!
