VMware users who appiled the Windows 7 updates from the barrage of February Patch Tuesday security bulletins were frustrated to learn that the patches also made VMware stop working. Oops.
One of the reasons that there is often such a considerable amount of time between a vulnerability being identified and a patch being developed to remedy it is the extensive testing that goes into making sure that the patch works as advertised, and without breaking anything else. Sometimes, despite these efforts and the best of intentions, things slip past.
Apparently, a couple of the patches for Windows 7 (2482017 and 2467023) contained elements from the upcoming Windows 7 SP1 which adversely impact VMware. The good news is that Microsoft and VMware had already been working together in anticipation of the release of Windows 7 SP1, and VMware was already developing an update to address the problem. So, following the issues from February Patch Tuesday, VMware released an update within 24 hours that resolves the problem and gets VMware working properly on Windows 7 once again.
