Upgrade repair install asking for non existent password

Ok my friends Gateway laptop had some issues all due to poor maintenence and installation of ever piece of junkware and toolbars known to man. It kept getting blue screens right after getting fully booted and I found and solved that issue....he had never done one single update, no service packs...NOTHING! It ran better after doing a few initial updates but then windows update failed to apply the SP1 update so I manually downloaded it and installed it.

It runs 90% better but till not up to par and I was trying to avoid a total wipe and fresh install so I was doing an upgrade repair and it keeps getting to a point where it asks for a user name and password....he has never set a password on this machine by the way. There is no way to get past this screen because any name entered or not entered gives a error message about not being to contact a domain or something to that effect.

Any ideas on how to get past this? If not how to I go about abondoning the upgrade install because when it boots it does ask which OS to boot the existing 7 install or continue the upgrade...I basically want to remove the new install from this boot menu and maybe talk him into a total wipe.

You would already be signed into Win7 to run the installer from desktop to do a Repair Install
and it would not ask you to sign in again.

Are you referring instead to doing Startup Repair from boot which will prompt for password if run from F8 options or System Repair Disk. You can leave it blank to get past it, Or run it from the booted installer.

I am running an "upgrade" from Win 7 but I just tried it again and there is no password but it keeps asking for it so I am going to tell him he needs to wipe it clean and start over.

How exactly are you running this "Upgrade" when it prompts you for password?

Follow these steps to get a perfect Clean Reinstall - Factory OEM Windows 7

I am running the install from within Windows and selecting the upgrade option in order to repair the load of problems he has. I have done many Win7 installs and have never seen this user/password screen that it is coming to so I have no idea what it is and he has no system password set and never has had one.

I have his current install running oodles better but have an update installation issue which I am trying to resolve right now which is possibly caused by some malware. If I cannot get it to 100% I am going to tell him to back his files up and show him how to use the built in recovery options and be done with it. I mean he has like 7000 pics using like 80 gigs of space and with everything else installed his hard drive is almost full so he has other issues.

Thanks for you reply but I am marking this as solved.

In the time it's already taken he could have backed up to external and gotten the vastly superior Clean Reinstall - Factory OEM Windows 7.

If he'd stick with the tools and methods in the tutorial he will get and keep a perfect reinstall.

A Repair Install should not prompt for any password ever. He has more serious problems. Have you run a Malwarebytes scan yet? I'd go even deeper with a boot scan of Windows Defender Offline

I'd also establish a Clean boot and reboot to see if the prob persists: Troubleshooting Steps for Windows 7
