Hi Thomas,
Thanks for posting in the community. We are happy to help you.
Per your description, my understanding is that you failed to use your business account to set up a Windows user profile on the computer.
- If not, please point it out and let us know.
- If so, generally, you can select "Switch user" in the current Windows user profile, select "Other user" and enter the credentials for your business account. I'm wondering if you have tried the above steps to switch to another Windows user profile.
If you have already tried the same steps and failed, I would like to collect more information.
- Is the computer connected to your company's network?
- Have you contacted your company's IT team? Generally, this would be the most efficient way to handle this case for you.
We look forward to your response. Thanks for your cooperation.
Sincerely,
