When you say 'update to Windows 10 stalling at 99%' are you referring to upgrade to Windows 10 is stuck or unable to update Windows to different builds?

If you are referring to Windows updates then follow the steps and check.

Run the Update Troubleshooter on the computer.

Windows 10 has a built-in troubleshooter to check and fix issues with Update. I would suggest you to run this troubleshooter to check if the issue is with your Windows update.

Refer these steps:

• Press Windows key +X, select Control panel.
• Change the view by option on the top right to Large icons.
• Click on Troubleshooting and click on the view all option on the left panel.
• Run the Windows Update troubleshooter.
• Restart the system and check if the issue is resolved.

Do let us know the status of the issue to assist you further. Thank you.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
