Microsoft's own security software appears to be the reason the free media player VLC suddenly started freezing for up to 33 seconds on fast Windows 11 computers, and open-source developers are getting blamed for a problem Windows itself caused.

• Windows Defender, Microsoft's built-in antivirus, started locking away VLC's startup files, forcing the app to grind through security checks every time someone opened a song or video instead of just reading its normal files.
• Proof came when someone opened the exact same VLC file on Linux instead of Windows — it loaded in one second instead of 33, showing the problem was Windows, not VLC's code.
• Other small, independent apps like Paint.NET have hit the same wall, and their volunteer developers had no choice but to build their own workarounds since Microsoft never fixed or even acknowledged the issue.
• A separate mandatory Windows security update around the same time broke video games, caused crashes and restarts, and messed with login PINs — and Microsoft blamed RGB keyboard lighting software instead of its own patch.
• Microsoft's own apps, like its Media Player and Edge browser, get smoother treatment on Windows than outside apps do, and regulation in Europe already proves Microsoft can fix this double standard when legally forced to.

Outlook: expect more friction as Microsoft keeps pushing aggressive security updates, with small independent developers stuck doing the cleanup and taking the public blame while Microsoft faces no real consequences.
