How to fix Hyper-v accelerated timer?

Question

Virtualization

Hello, the thing is, I installed windows 7 x64 on hyper-v running Windows 10 pro 1803. The
trouble is that the second hand in the guest system runs like wild, all animations have accelerated 10 times, double click cannot be done, because speed is needed correspondingly, the time in the system runs well, almost an hour in 5 minutes. Cursors blink like wild when typing.
Can't find where is the problem? Maybe Hyper-V itself with problems in the new system, maybe the outdated win7 is poorly supported by the new hypervisor, maybe the drivers fail.
ps - I found such a thing that initially the guest system works relatively adequately, but then the update center apparently installs guest services and drivers and the system starts to accelerate.
System generation 1, config version 8.3, the rest of the systems are Linux with config version 8.0, and generation 2, did not notice the failure of the timers there.
Maybe there is an adequate set of integration services for win7?
