I do have the same issue that has happened to you after installing VMware WS 6.5 inside Windows 7
Its so weird having that weird new USER ( __vmware_user__ ) on the Windows 7 Start Up
i have checked all over the computer & drive C.. there is nothing related to that user.. or any new user in it.. so it is pretty messed up thsi issue that has occured in Windows 7.. by simply installing WMware WorkStation 6.5..
On my computer, it appears VMware did not install fully.. since inside *Program Files in drive C.. it does not have sufficient files to run the program(not even the .exe file and only 1 folder but empty), I had it installed before on WIndows XP and it had allot more files and it ran perfectly the install
Well i hope someone.. finds a solution to the problem that me & z_hn are having on Windows 7, we want to REMOVE that New user.. and Fix & erase what got installed from this *Currupted VMware (I actually dont even think it got installed.. so i'll simply call it currupted - it is not in Start Menu & in program Files the VMware folder is kinda Empty)
I have managed to fix the Erasing that New User "__vmware_user__"
Reboot the computer, Start clicking F8 while computer starting and choose Safe Mode
Once in Safe Mode, go to Control Panel and chose something like Administrative Tools (IF you don't see it click "All Control Panel Items")... then choose Computer Management, then select in the Left Side Panel "Local Users and Groups"... then select the folder "Users" in there you should read that New User "__vmware_user__"... just right-click on it and choose Delete... after that Go Back on to where you see the folder "Users"... but this time choose the folder "Group" in it also look for the New User "__vmware_user__" and do the same Right-Click and Delete
and thats it.. Reboot the Machine.. afterwards you may delete the VMware folder from inside the Program Files since it doesnt work in Win 7... well that was for me according to my issue
I hope it helps... it removes that random user in Start Up Screen
