If space wasn’t an issue, deleting anything from the following registry key should help you pass this error. However, for some reason, if you encounter another error such as below with code 0xC1420127 during the upgrading, check the free space on your C: drive to make sure it has at least 50 GB of free space left. So if you encountered one when updating your Windows 10 to the latest released build, applying this method should be good enough to get you through it. The error could occur on any Windows 10 build. Successfully done either one of the options will get you through this update error and have the new Windows 10 build updated on your computer. If, however, it didn’t allow you to delete the folder due to the permission issue, try to rename it instead. It’s a temporary folder that saves all files downloaded and required for Windows 10 build upgrade.ĭelete the entire folder first and run the update again. Turn on the Hidden items option in View tab,Īnd you will see a hidden folder named $WINDOWS.~BT showing up.

Open File Explorer by either clicking on the file folder icon on the Taskbar or pressing Win+E keyboard shortcut, and navigate to C:\ drive that hosts the Windows system. However, if you are experiencing the same as I did, here is what you can do to fix it to continue on the update process to upgrade your Windows 10 to the next release. Digging into error log entry in Event Viewer doesn’t reveal much useful info either. I have a Windows 10 computer that has been unable to update to the latest released build since 10565 due to an error occurred every time when I was trying to update to any newly released built through Windows Update, see a screenshot below:Īs you can see, there isn’t much information there telling me what went wrong.
