Whenever I try to update my computer from build 14316 to a later build (in this case, 14361), it detects the update and seems to download regularly until the "Preparing to install updates" step reaches 100%, at which the "Insider Preview Build 14361" text disappears and Windows Update appears to do nothing.
I have left my computer on while this step is happening for over 8 hours and nothing happens once the update process reaches "Preparing to install updates 100%".
Event Viewer shows that WindowsUpdateClient fails with the error code 0x80240020. Whenever I run the Windows Update Troubleshooter, the update simply redownloads and the error occurs again.
If it makes any difference, I recently switched from a Microsoft account to a Local account, although Insider Builds are still linked with my Microsoft account.
Thanks in advance!
