How To Disable Time Synchronization in Virtual PC

We often install trial version of operating system as virtual machine in Microsoft Virtual PC environment. This trial version will expire after 60, 90 or 120 days. To avoid this expiration, you can stop the time synchronization between vm and host machine.

How ?

Edit the virtual machine configuration (.vmc) file using text editor (notepad.exe) then add this element inside element :

<components>
<host_time_sync>
<enabled type="boolean">false</enabled>
</host_time_sync>
</components>


Then restart your vm. Now your vm will maintain separate system date/time from host machine.
