Windows7 - the First BSOD?

Just reported today? Sorry ... not!

This will happen a lot due to legacy drivers. The same issue comes down from the Vista experience of using old network drivers and is documented in a KB.

The actual driver conflict is with Tdx.sys (both 32-bit and 64-bit versions) which was fixed on Vista via SP1.

Its not only Symantec but also Alwil/Avast and SuperAntiSpyware that have support forums talking as early as last January. Keep going through the forums and it affects a whole lot more vendors.

This is not a new issue apart from the recently reported flaw in SRV2.sys which crashes the SMB2 driver: Crenk and Tom's Hardware

Further user experience of SMB2 complicated by outdated drivers causing issues with their security product is documented in the Microsoft forum.

The solution of course is of course to use compatible and updated drivers. This is a step most users skip and are sorry about later: Windows Compatibility Center
