Microsoft Virtual PC Security Options

Ben Armstrong continues to keep us up-to-date and up-to-speed on Microsoft products.  This time, he focuses on Virtual PC security options.  The product has a set of built in security options that allow you to restrict access to various parts of the application for non-Administrative users.  When all options are enabled, a non-Administrator user can only launch preconfigured virtual machines.

Ben continues by saying:

Now the problem is that this setting has to be configured by an Administrator on the computer in question.  If you are doing a large deployment you can avoid this by simply placing the correct value in the registry.  The Virtual PC security options are stored in a hexadecimal DWORD called 'Locks' under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual PC\5.0\Security.  The value of the DWORD determines what is restricted.  The values are as follows:

0x001 = Disable access to the Virtual PC Options
0x002 = Disable access to virtual machine settings
0x008 = Disable access to the new virtual machine wizard
0x020 = Disable access to the virtual disk wizard

If you want to disable multiple items - you just add the values.  So a value of 0x00A would mean that the settings and new virtual machine wizard were not accessible.  And a value of 0x02B would mean that everything possible was disabled.

You might notice that the numbers for these options are not a strict binary progression (4 and 16 are missing).  This is because of security options that were attempted in earlier builds of Virtual PC that did not prove to be useful or reliable.
