1. Windows 10 ‘Defer Upgrades’ (May not work on newer versions of Windows).

If you have problems upgrading to Windows 10 Pro, you may be able to defer the upgrade. This allows you to defer the upgrade without stopping your ability to download other updates.

  1. By selecting the gear icon from the Start menu or by searching in the search bar, you can access the Windows Settings app. 
  2. The ‘Advanced options’ submenu can be found under the ‘Update and Security’ section.
  3. Following that, there will be an option called ‘Choose how updates need to be installed’ and below that, ‘Defer feature updates’.
  4. The change may take effect after restarting your computer.

2. Use the Windows 10 Update Assistant

One of the ways that we’ve learned to use, is using the Windows 10 Update assistant. We should mention that this only works when you are going from one major version (1607,1709,1803,1809 etc.) to the latest. To use this, head over to the Windows 10 download page. This will then show you at the top if you’re able to update with the latest and will give you an option for ‘Update Now’. If you go here and then follow through the steps, you will be on the newer version which can fix many issues, including the update issues.
