Issue: How to fix Windows 11 upgrade error 0xC1900101 – 0x50016?

Hello. I tried to upgrade my computer from Windows 10 to Windows 11 and it failed. It gave me an error code 0xC1900101 – 0x50016. What should I do? 

Solved Answer

As more and more people seem to switch to Windows 11, more reports emerge about various errors that prevent people from upgrading their systems. Some users encountered a Windows 11 upgrade error 0xC1900101 – 0x50016. Changing to a newer version seems to be more complicated than first thought.

Although the error 0xC1900101 – 0x50016 seems to appear because of a driver-related issue, there might be a lot of other things causing it. First, you have to make sure that you completed recommended steps before clicking the “Upgrade” button:

  • Check if your PC meets the minimum requirements to run Windows 11.[1]
  • Enable TPM 2.0 on the BIOS.[2]
  • Enable Secure Boot on the BIOS. This will disable non-Microsoft processes from running and possibly interfering with the upgrading process.
  • Back up important data to minimize the risk of it being lost during the upgrade.
  • Clear up disk space because if you are trying to install Windows on a drive that has low disk space, the installation will fail. You must check the free space on your drive before proceeding. There should a minimum of 30 GB of space.
  • Uninstall conflicting and non-essential apps because they can interfere with the upgrade process.
  • Check and fix system errors. You can do that easily with a repair tool like ReimageMac Washing Machine X9.
  • Disconnect non-essential peripherals, like SD cards, USB flash drives, microphones, etc.
