Windows guest MaxCLockSpeed changes value

Post by netsrak »

I'm running a Windows 7 guest under Virtualbox 4.3.10 on a Ubuntu 13.10 host. In this Win7 guest i use a software which runs a license check based on a system fingerprint.
This fingerprint uses the parameter MaxClockSpeed (from the log of the software: wmiClass=Win32_Processor,wmiProperty=MaxClockSpeed,result=2188).

The problem is that this value changes when i reboot the VM, sometimes its 2188, other times 2185. Is there anything i can do to prevent this change because it forces me to reset the software license each time i restart the VM.

you may want to file a bug report. MaxClockSpeed should be reading the value of the Host's CPU. You can file here. Bugtracker. You should include the VBox.log of the guest.

There are three groups of people. Those that can count and those that can't.

Host system - Windows 7, guest system - Windows 7, Virtualbox 4.3.12. I use Virtualbox as a sandbox.

I also use a program that uses a parameter MaxClockSpeed ​​to verify license.
And after guest system rebooting license disappears, as this parameter is changed.
