How to disable Time Synchronization under Windows Virtual PC


In some circumstances you need to disable the automatic time synchronization with your host which occurs per default every 15 seconds.

I had tested the described scenario from Ben Armstrong (Virtual PC Guy) and it works as well for Windows Virtual PC under Windows 7.

Find your *.VMC file of your virtual machine and search for the following section :

<host_time_sync>
    <enabled type="boolean">true</enabled>
    <frequency type="integer">15</frequency>
    <threshold type="integer">10</threshold>
</host_time_sync>

If you want to disable time synchronization then change the yellow marked parameter to “false” and reboot your VM.

<host_time_sync>
    <enabled type="boolean">false</enabled>
    <frequency type="integer">15</frequency>
    <threshold type="integer">10</threshold>
</host_time_sync>
