It’s timely that Microsoft has released a massive slew of updates to the Windows 10 Creators Update. With Petya striking overnight, attacking unpatched systems with a nasty bit of ransomware, it’s worth taking this update as it includes a bunch of fixes.
The change log, detailed at MSPowerUser, doesn’t specify any security-specific fixes but a number address flaws in networking and web browser functions. And this makes me suspect potentially exploitable vulnerabilities might have been addressed.
The fixes are available through the unusual Windows Update channels.
