Unable to upgrade windows 10 1803/1809 to 1903 0x800711C7 Error
Hi guys,
I can't upgrade windows 10 Enterprise 1803/1809 to 1903. Feel like I've tried everything here.
Tried Windows Update. Doesn't work. [Fails to update during the reboot bit, and simply undoes changes]
Tried Windows Update/Upgrade Assistant. [Gets to about 23% during the reboot bit, and simply gives black screen telling me it's undoing the changes]
Tried Windows In-Place-Upgrade (using the Media Creation Tool). [Same as the Update/Upgrade Assistant above]
Tried disable Device Guard, Secure Boot, Virtualization Based Security [Same as the Update/Upgrade Assistant above]
Tried upgrade in clean boot mode but this doesn't work.
Tried the way:
- sfc /scannow
- Dism /Online /Cleanup-Image /ScanHealth
- Dism /Online /Cleanup-Image /CheckHealth
- Dism /Online /Cleanup-Image /RestoreHealth
- Stop Windows Update service, delete folder SoftwareDistribution from C:/Windows,
- Delete catroot2 folder from C:/Windows/system32
- Clear UEFI variables
- Disable Device Gaurd, VBS with the help of Device Guard Readiness Tools
- run Windows Update Troubleshooter
I have also replaced the device guard policy in audit mode, but result is nothing
Error code is:
0x800711C7 - 0x2000A
The installation failed in the SAFE_OS phase with an error during PREPARE_FIRST_BOOT
0x800711C7 - "This program was blocked by Device Guard because it violates the code integrity policy installed on this system" - but Device Guard is disabled.
The problem is on all personal computers in the domain on which I had enabled device guard (Windows Defender Application Control).
It's my log from C:\$WINDOWS.~BT\Sources\Panther\setuper
2019-11-12 11:55:08, Error MOUPG CDlpActionImpl<class CDlpError - Pastebin.com
Each time the update reaches 23% and changes are rolled back.
Any other ideas for resolve this problem?
