Hi Nyamsuren Purevsuren

Hello Nyamsuren Purevsuren,

Thank you for reaching out to Microsoft Q&A!

The error 0xC0000005 typically indicates an Access Violation, often caused by system file corruption, hardware conflicts, or interference from security features like BitLocker. Once you successfully update to 22H2, the KDF issue should resolve itself as newer Windows versions use KDFV2.

Solution 1 - Run built-in troubleshooter:

• Open Settings > Update & Security > Troubleshoot > Additional troubleshooters
• Run the Windows Update troubleshooter > Follow the prompts
• Open Command Prompt as Administrator > run:
  • sfc /scannow
  • DISM /Online /Cleanup-Image /RestoreHealth

Solution 2 - Disable BitLocker (if enabled)

• Go to Control Panel > BitLocker Drive Encryption
• Select Turn off BitLocker for the system drive > Restart

Solution 3 - Manual Update:

1. Download the 22H2 update manually from Microsoft's Update Catalog.
2. Use the Media Creation Tool to create installation media following this guide: Reinstall Windows with the installation media - Microsoft Support.

Solution 4 - Temporary disable protection software:

• Turn off all third-party antivirus softwares (if any)
• Temporarily turn off real-time Microsoft Defender antivirus protection in Windows Security.

Disclaimer: Keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once the issue is fixed.

Solution 5 - Reset Windows Update with Command Prompt (Admin), running these one by one:

• net stop wuauserv
• net stop cryptSvc
• net stop bits
• net stop msiserver
• del /s /q %windir%\SoftwareDistribution\*
• del /s /q %windir%\System32\catroot2\*
• net start wuauserv
• net start cryptSvc
• net start bits
• net start msiserver

A few other things to pay attention to:

• Ensure your system meets minimum requirements for Windows 10 22H2
• If the device uses newer Intel CPUs, check for BIOS updates and hardware
