If you go nuts about something like this I think you're better off with a shrink or something. Yes, the issue is annoying but it is easy to fix as you can disable the winkey from within Windows. I searched for an article explaining the regtweaks you need to make and found the following link at microsoft.com: How to disable the keyboard Windows key
Below is what it says:
To disable the Windows key, do the following steps:
1. Click Start, click Run, type regedt32, and then click OK.
2. On the Windows menu, click HKEY_LOCAL_ MACHINE on Local Machine.
3. Click the System\CurrentControlSet\Control folder, and then double-click the Keyboard Layout folder.
4. On the Edit menu, click Add Value, type in Scancode Map, click REG_BINARY as the Data Type, and then click OK.
5. Type 00000000000000000300000000005BE000005CE000000000 in the Data field, and then click OK.
6. Close the Registry Editor and restart the computer.
Note: before doing this you should follow the warning on that page and make a backup of this regkey by exporting it via regedt32. If you want to undo this change than import the exported .reg file and the winkey should work again.
Again, this is a temporary fix that disables the entire winkey in the Windows vm and should be repeated for each Windows vm you've got. At the end of the day it is VMware who needs to resolve the issue, this is just a workaround!
