This issue has been fixed with the release of VMware Workstation 10.0.4.  VMware recommends that if you made changes to the config.ini that you remove the entry or change the value to “FALSE”.  The Workstation download can be found here.

When powering on a VM in Workstation 10 after rollup KB2995388 I see the following.

VMware is aware of the issue it would seem and there are three workarounds so far.  VMware official blog has this about it.

1.  Uninstall KB2995388 (This is an optional update).
2.  Edit the config.ini found in C:\ProgramData\VMware\VMware Workstation         and add the line:  vmmon.disableHostParameters = “TRUE”
3.  This is untested by me but it is reported that if you open Workstation in                   administrative mode (with admin rights), that it won’t have the problem.

Reboot your computer and your VMs should work again.

I did notice after making the change that the first time I start my VMs I get:

I chose “No” on both and the VMs now boot without issue.
