Date-Time synchronization won't turn off

This issue was listed a year ago, and I didn't see any responses. I too have unchecked the "enable" in Parallels Time Synchronization but the date and time are still synched. I am using build 5608. I have also made sure that Windows internet time synchronization is also off. I reinstalled the Parallels tools and that didn't change the behavior. Any ideas?

 

regedit in Windows and set
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PrlTime\Start value to 4

 

Thanks John. The setting for this file was 2, and I changed it to 4 -- I assume (and please confirm) that this is supposed to be hexadecimal. With this change, will Parallels tools now toggle the date-time synchronization function as expected?

 

It is no difference up to value 10
You need to restart VM also

 

I made the suggested change (the, shut down Windows, quit Parallels, restarted, confirmed that the change had been made with RegEdit, and the problem persists. Any other things I can check or do?

 

The ImagePath for PRLTime is currently "\??\C:\WINDOWS\system32\drivers\PrlTime.sys". Is that correct?

 

Yes, it is correct, I will try to check problem, but I need some information, if you create ticket in support I will be able to establish test case, and submit case.
