Windows 7 VPC virtual machine does not automatically synchronize with the host

The virtual opportunity in the Virtual PC is automatically synchronized with the current host time. However, many times, testing virtual opportunities will run after a long time, but you will find that due to time synchronization, some windows will expire, and the testing software will have a validity period, which is very important to solve this problem, on Windows 7, the traditional VPC setting method is invalid because the VPC of Windows 7 is redesigned.

For more information about how to set up VPC, see http://blogs.msdn.com/ B /virtual_pc_guy/archive/2007/11/28/disabling-time-synchronization-under-virtual-pc-2007.aspx.

The key is a vbs script.

   1: 'Title: Script to disable timesync for a VM. 

   2:  

   3: 'Usage: cscript ScriptName <vmname> 

   4: Set objVPC = CreateObject("VirtualPC.Application") 

   5:  

   6: 'Get virtual machine name from command-line parameter 

   7: Set objVM = objVPC.FindVirtualMachine(WScript.Arguments(0)) 

   8:  

   9: 'Disable TimeSync During Boot Time

  10: errReturn  = objVM.SetConfigurationValue("hardware/bios/time_sync_at_boot",false)

  11:  

  12: 'Get object for GuestOS

  13: Set objGuestOS =objVM.GuestOS

  14:  

  15: 'Disable TimeSync During VM Execution

  16: objGuestOS. IsHostTimeSyncEnabled = false

I saved it as vpcdisable. vbs. The command to set Windows XP mode not to be synchronized with the host is as follows:
