.\fix_0x80070643-icrease_WinRE_partition_size.ps1

The "2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441)" update often fails with error 0x80070643.

Actually the reason for failure seems to be that the WinRE partition is too small to install an BitLocker fix.

The partition needs to changed in a particular way that is so finicky that Microsoft has provided a script to perform necessary actions over here. Unfortunately this script cannot run without errors and thus fails.
