I recently bought and repaired a laptop, but it turns out its Windows installation is tied to a corporate system. During setup, I'm prompted to log in with a corporate email. I reached out to the company's IT department, but they don't have any record of this laptop's serial number. I've searched Microsoft forums for solutions but I'm not sure what terms to use or who else to contact to free the device. Any suggestions?

If you're looking for a quick fix, just disconnect the laptop from the internet, buy a new copy of Windows 11 Home, and create a bootable USB from another computer. Boot from that and install your own OS.
You can also install an older version of Windows 11 as an offline machine. Set it up without the internet, and once it’s up and running, reconnect online and you should be good to go.
What you're experiencing is likely due to Windows Autopilot or Azure AD enrollment, not just something local on your laptop. Even a full reinstall won’t remove these settings if the device’s hash is registered with a company's tenant. Only the original organization can remove that link. If they can't find it, try asking them to check using the hardware hash instead of just the serial number.
Check out this Dell-specific guide for removal instructions. If you have a receipt proving you bought the device, there's a way to have it removed from Microsoft Intune. Alternatively, the original organization can also take it off their list if it's stale.
Unfortunately, only the company that registered the device can release it from their system. If you've repaired the laptop, did you change the motherboard? If the motherboard was swapped, that might explain why the IT department can't find your serial number since it ties everything to Mobile Device Management.
Also, Microsoft has occasionally stepped in to help with these situations. If you're able to contact the original company, it might not be successful, but it’s still worth trying to open a support ticket.

True, but keep in mind that using Linux might not be a complete fix either. If the device is enrolled in Azure, there could be some configurations that come down even for Linux as well.
