A Hypervisor Error in Windows 11 after an update usually occurs because the update re-enables Hyper-V or changes virtualization settings, causing conflicts.
To fix it:
First, disable Hyper-V and related features. Go to Turn Windows features on or off and uncheck Hyper-V, Virtual Machine Platform, and Windows Hypervisor Platform, then restart your PC.
If the problem continues, open Command Prompt as Administrator and run:
bcdedit /set hypervisorlaunchtype off
Then restart again.
Also check Windows Security → Device Security → Core Isolation and turn off Memory Integrity if it is enabled.
Make sure your system drivers (especially chipset and graphics) are updated, and run system repair commands like SFC and DISM if needed.
In most cases, disabling Hyper-V after the update permanently fixes the hypervisor error.
