Time does not always sync in Windows

[Freddy @ LEF]

Hi.
I have a Mac with Parallels on it for my Windows instance. My set up is that my Mac runs with TimeZone Brazil and Windows TimeZone EU.
I have disabled the Time Sync, but the problem arises that Windows gets out of Sync, where I have to click the 'Sync Now' button to get the correct date and time in Windows. This should be automatically.

I'm having a similar problem after a recent Parallels update. I am running Windows 10 and now the Date/Time never syncs automatically. I suspect something didn't install correctly but I am not finding any guidance on how to fix this problem.
