You were absolutely correct in stating that this problem may be due to the 'vmappsdk' and 'vmdbcom' registry keys.
In fact, to fix the problem, you would need to grant 'Read Only' access to 'Users' group to the following keys (and subkeys): -
Additionally, for file type association: -
Thus, there are approximately over 320 registry keys that need their ACL (permissions) reset. I suggest assigning the following only: -
Administrators (group) - Full Access
System - Full Access
Users (group) - Read Only
This is clearly a huge overlook on the part of VMWare, which I'm fairly angry about as it took me a couple of days to trawl through regmon logs and to find all the keys as well as to write a script to reset the permissions.
Note however, that the above stated keys are only for the Workstation edition, so there may be many hundreds more for the Server edition.

Windows Vista Performance in VMware Workstation 6.0
One of the great new features in VMware Workstation 6.0 is its Windows Vista support. Vista can be used as the host operating system (HOS) and the guest operating system (GOS) for VMware Virtual Machines (VM). The question to us is how well Vista performs in VMware Workstation 6.0. This actually contains two sub-questions. (1) What is the performance of Vista as the HOS? (2) What is the performance of Vista as the GOS? To answer these two questions, we did a comparison of Windows Vista and Windows XP performance.
To answer Question (1), we ran experiments using the same virtual machine on the two different HOS's (Vista and XP) and compared the results. We ran a set of workloads to measure the CPU, memory, disk and network performance of the VM. Vista host performance is on par with XP, except that Vista itself consumes more memory than XP. This means that Vista leaves less memory for the use of VM's than XP.
To answer Question (2), we compared a Vista VM against an XP VM both on an XP host. We ran the same set of workloads as for the Vista host experiments described above. While Vista guest performance is on par with XP in most of our workloads, we did find a few cases that perform worse on the Vista VM than on the XP VM. To understand why Vista was slower in those particular cases, we conducted the same measurements on native physical systems, rather than on virtual machines. We found that Vista is slower than XP on native hardware almost to the same degree as on virtual hardware. This made it clear that VMware Workstation 6.0 wasn't introducing any Vista-specific overheads, and that the relative performance on Vista is as good as on XP.
The chart below shows some representative results from our experiments. The bars represent the ratio of Vista to XP performance when comparing the Host OS, the Guest OS and native. The benchmarks shown are: gzip from the SPEC CPU2000 suite, PassMark PerformanceTest, Iometer disk workloads, Netperf networking send/receive, and boot/halt (time taken to boot and immediately halt the OS). The workloads had minimal variations from run to run, e.g. around 3% in performance.
In conclusion, Windows Vista works great with VMware Workstation 6.0! Go ahead and have fun with our cool virtualization technology!
VMware Workstation 6.0 supports both 32-bit and 64-bit Vista. Our conclusion here holds for both 32-bit and 64-bit.
Please refer to "Performance Tuning and Benchmarking Guidelines for VMware Workstation 6" for more information about Workstation 6.0 performance.
