Windows 11 KB5072033 issues: Microsoft confirms a bug affecting WSL and more

Microsoft's Windows 11 KB5072033 update is the final one for 2025, addressing stability issues but causing errors during installation for some users. The update resolves white flashes in File Explorer but still shows flashes when opening new tabs. However, it introduces a bug affecting Windows Subsystem for Linux (WSL) networking when using certain VPN apps, leading to connection issues. Microsoft is investigating the WSL problem, with a fix expected in January 2026.
