1. 1 Press Windows key + R to open the Run dialog. Type 'msinfo32' and press Enter. In System Information, look at 'System Type' and 'BIOS Mode'. If it says 'UEFI', you can proceed. If it says 'Legacy', you may need to enable UEFI in BIOS. This step helps you understand your firmware setup.
2. 2 Press Windows key + X and select 'Windows Terminal (Admin)' or 'Command Prompt (Admin)'. Run the command 'sfc /scannow' and press Enter. This scans and repairs corrupted system files. Wait for it to complete; it may take 15-20 minutes. If it finds issues, it will fix them automatically.
3. 3 After SFC, run 'DISM /Online /Cleanup-Image /RestoreHealth' in the same admin terminal. This repairs the Windows system image. It may take up to 30 minutes. This is a deeper repair that fixes corruption SFC can't.
4. 4 Press Windows key + R, type 'optionalfeatures' and press Enter. In the Windows Features dialog, uncheck 'Hyper-V', 'Windows Hypervisor Platform', and 'Virtual Machine Platform' if they are enabled. Click OK and restart if prompted. This disables the hypervisor temporarily to see if it resolves the crash.
5. 5 Update your BIOS/UEFI. Visit your PC manufacturer's support website, find your model, and download the latest BIOS update. Follow their instructions carefully. An outdated BIOS can cause hypervisor errors. This step is advanced; if you're not comfortable, consider seeking professional help.
6. 6 If the error persists, boot into Safe Mode by holding Shift while clicking Restart in the Start menu. Then go to Settings → System → Recovery → Advanced startup → Restart now. In Safe Mode, uninstall any recently installed software or drivers that might conflict with virtualization.
