Windows blue screen error due to smbusdh.sys

If you have initially installed Client Security Software (CSS) 5.41 or previous versions, you may have a SMB Device Hub driver (smbusdh.sys) that can cause a Windows Blue Screen error. If you have over-installed CSS 5.42 or later without first removing CSS 5.41 or previous versions, then the SMB Device Hub will not be updated as well.

Lenovo has addressed a SMB Device Hub issue in Client Security Software (CSS) 5.42 release. If you have initially installed CSS 5.42 or later, this information does not apply to you.

Any system running Microsoft Windows 2000 or XP configured initially with Client Security Software (CSS) 5.41 or previous
