Windows Update Error 0x80240020
Just before we start, let me tell you this straight. You don’t have to run any troubleshooter or delete any file to fix this. Rather you need to enable one option which can automatically login with your account and complete the installation. That said, always make sure to only kickstart the update process when you get an instruction to do so.
The operation did not complete because there is no logged-on interactive user
Go to Settings > Accounts > Sign-in Options > and toggle on the option which says “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart“. Once done, it will make sure the interaction part is removed from the update in progress.
This option isn’t available if your device is joined to a domain, or if work or email policies are applied to your device by your organization. If this doesn’t work, the next option is a registry hack. You not only you should be an admin, but also understand that registry hacks are sensitives. Make sure to take backup of your registry, and create a system restore point. Type regedit in Start search and hit Enter to open the Registry Editor. Locate the registry key: If it doesn’t exist, you can create it. Right-click on the WindowsUpdate Key, and then select New Key, and name it as OSUpgrade Then create a new DWORD (32-bit) Value with Name = “AllowOSUpgrade” (without the quotes), and set the Value = 0x00000001.
Restart your computer and see.
While updating, be around the PC to interact with the prompts to complete the update.
