Troubleshooting Windows 10 Upgrade Issues

Remember: With any new OS release, there’s bound to be issues. If you’ve come across one, have patience. We’ll be covering major issues for upgrading and clean installing Windows 10 here, along with future articles and in the comments below this guide.

Windows 10 Hasn’t Promoted You to Upgrade, Yet

Microsoft is rolling out updates so as not to bog down the servers as everyone flocks to download Windows 10 and upgrade or clean install. If your Windows 10 hasn’t prompted you to upgrade, yet, you can manually install Windows 10 by following our instructions here.

This is a catch-all error that points to an issue with the pre-downloaded Windows 10 installer on your computer.

In order to fix it, navigate to: C:\Windows\SoftwareDistribution\Download.

Delete everything the folder, then reboot your computer.

Open Windows Update and run it to begin the download of the Windows 10 installer again.

This error might point to a hardware driver being incompatible with Windows 10 that wasn’t caught by the Get Windows 10 App. Unfortunately, it won’t point out what driver, so you’ll need to do research on your drivers to find the culprit and see if there’s a workaround.

If that’s not one, yet, there should be in the future either on the driver or Windows 10 end.

If the Windows Update server fails, or goes down, this error usually indicates that during the upgrade process. Don’t use a VPN connection if possible when upgrading to Windows 10; if your Internet connection is spotty, try hardwiring for the process to help. In some cases, the Windows Update server may go down or be bogged down as many are trying to do the same thing you are, if that’s the case, try again later.

This error can also sometimes indicate an issue with your computer’s partition. If you have a recovery or system reserved partition, Windows 10 will need to utilize it during the upgrade process. If there’s not enough room or something is amiss, it may trigger this error. If that’s the case, you’ll need to use third party software to make either of those partitions larger for the upgrade

This error points to an incompatible app on your computer that’s blocking the Windows 10 upgrade process. Again, this won’t point out what app, so you’ll need to do research to find out what’s causing the issue, uninstall the app and try the upgrade again.

Installation Errors: 0xC1900200 – 0x20008 & 0xC1900202 – 0x20008

These errors indicate your computer may not meet the minimum specifications to upgrade to Windows 10. Check with your computer’s manufacturer to ensure you’re able to upgrade to Windows 10.

Installation Errors: 0x80070070 – 0x50011, 0x80070070 – 0x50012 & 0x80070070 – 0x60000

These errors typically mean you don’t have enough hard disk space to upgrade to Windows 10. Clean up your PC, move things to a removable drive or the cloud, and try again.

Error: The update isn’t applicable to your computer

This means you haven’t installed all required Windows Updates before upgrading to Windows 10. Cancel the installer, reboot your PC, and run Windows Update. Install all updates, then try to upgrade again.
