I bought a computer from a company going out of business. It came as-is without any discs or manuals. So like an idiot I took it. I turned it on and found that it was on some kind of network and a username and password is needed to start windows. I tried starting it in safe mode but the same prompt for username and password comes up. Is there anyway I can override the login?

Practical, safe options for after buying a company PC with no media.

First decide whether you need to keep data or can wipe and reinstall. Quick check: if the machine was joined to a corporate domain you may be seeing domain authentication rather than a local account. You can force a local account sign-in by prefixing the username with .\ (for example .\username) to tell Windows to use the local SAM. If that succeeds, create a local administrator, back up files, then either remove domain settings or reinstall.

If files must be preserved, boot a live USB and copy them off before attempting resets. Use an Ubuntu live image () and write the USB with Rufus. Be aware that BitLocker or EFS protection will prevent copying without keys; if encryption is possible, locate the recovery key first. Make a full image before changing anything (tool: Clonezilla).

As noted, password-reset tools exist. Two well-known, widely used options are the open-source Offline NT Password & Registry Editor (ntpasswd) or a bootable toolkit like Hiren's BootCD. These let you boot the machine and reset or blank local account passwords. Read each tool’s documentation, image the drive first, and follow steps precisely.

If you prefer a clean start, download a legitimate Windows ISO from Microsoft (Software Download) and reinstall. That removes domain ties and stored credentials but destroys data. If ownership or encryption is uncertain, or if the machine might still be company property, consider professional assistance. Do not attempt to access systems you are not authorized to use.

You can keep fingers crossed and hope that user Administrator (in SAFE Mode) has no password.

Otherwise perhaps try (at your own risk)
