windows 11 pro update os issue
2 TopicsPC on Insider Preview 26H2 ... Windows Update tries to install 25H2 and fails
My PC is running Windows 11 26H2 build 26300.8935 with an expiration of 8/11/2026. Windows Update keeps trying to install 25H2 but fails with error code 0xc1900101. My BIOS and all drivers are up to date. I worked with Windows support .. case number 7106637314 ... and they were unable to help. Wondering if I need to use the 'Unenroll Device' button in the Windows Insider Program tab in settings. Will I need to install 25H2 via iso file as an in-place repair upgrade?363Views1like5Comments
