Windows clock often goes "out of sync" for a few seconds

    I have a problem with the clock of my Windows: often, during the day, it goes ahead ot 2 hours. E.g., if it's 8:40 AM, the Windows clock goes to 10:40 AM, while the Mac clock remains at 8:40 AM. After a few seconds, the Windows clock returns to the correct time (8:40).
    I'm in the Rome timezone, UTC+2, so maybe the 2 hours shift is related to this.
    This happens several times during the day (every 1-2 hours) and it's quite frustrating because a couple of software that I use have some issues due to this.

    I already have the setting "Sync from MacOS X" in the Parallels options, as explained in this article:
    I've already tried several networking settings (only shared network, only Wifi/ethernet), but nothing changed.
    Actually, also in the previous MacBook that I had up to some months ago, I had the same problem.
    I have all the software updated to the last version (Windows 10, MacOS X, Parallels Desktop).
    Do you what could cause this problem and if there is a solution?

    Hi @smartm1, have you reinstalled Parallels Tools for the virtual machine? If not, please start your virtual machine and go to Action( From Mac menu bar) and select "Reinstall / Update Parallels Tools" to fix the issue.

    Hi Paul, I've tried to reinstall the Parallel Tools, but the problem is still happening.
