Windows 10 VM freezes for 5 to 15 seconds regularly since High Sierra - Parallels 13.0.1 (42947)

[VadzimP]

Thanks a lot for sharing this.

Maria,
I would like to add some info for situation. In fact problem was not solved as I described above. In a few weeks it arize once more and freezes became really awfull.
I updated Paralells to ver 15 but it doesn't help. As I see, some process of Windows trying to connect to net about 15-20 sec and during this process Windows stopped. I prepared another Virtual maschine and install only some necessary programs. It works fine. Old VM could be executed with the same problem as earlier. As I see, problem is in some incorrect Windows service.

I've been fighting this problem since late 2019. I have been wondering if it's the SSD going bad on my MBP late 2013 w/ MacOS 10.14.6. I just disabled TRIM support on my drives connected to the VM and am waiting for it to complete "checking the disks after improper shutdown". I couldn't do anything my machine was completely locked up... It's nearly the 10th time I've seen this message... ugh! Anyway, hopefully that will resolve it for me. I beleive TRIM isn't supported on older Apple SSD's (I think it is on newer SSD's but I could be wrong). If this doesn't resolve it, I'm going to look into O&O' Shutup10 which can disable a lot of the network "noise" that comes with Windows 10

It looks like disabling TRIM support on the drives for my Windows VM did the trick! I have Spotlight indexing enabled, ran Windows updates while running VS2019 and Docker Desktop, all without freezing! I ticked it in a previous version of Parallels Desktop and didn't think about it. My guess is now it's attempting to implement it possibly at the H/W level and it's not supported on my my MBP late 2013's SSD.

I have Windows Home (not Pro) and I too am getting the freezes as describe. Further, the Windows Task Bar shuts down until I click on it, including the time and date. I have reinstalled Parallels Tools several times and that does not fix the issue.

I'm also getting freezing with Mac OS 11 + PD 16, random freezes.

Similar issue... MBPro 16Gb, 1TB screamin' Aura Pro X2 SSD, Parallels 16, macOS 11.3. Windows 10 pro and Home VMs freeze-up 5-10 times per day for up to 40 seconds. However, during the freeze-ups, macOS is completely unaffected. I can work completely normally in macOS while the Windoze VMs are frozen solid. Annoyed by the behaviour and perturbed that the issue appears to have been around for years without a clear resolution.

Any soultiuons to the freeze ups?

Hello Michael,
A solution from another thread in this forum: Go to the MacOS Preferences > Spotlight and disable searching the Parallels VM folder below the Privacy tab by adding this location to the list.

Hats off to you! I found this post after noticing the slowdowns coincided with Windows task manager showing 100% disk utilization.

I've been going for two days with no freezes after I disabled TRIM in Windows (it's still active in the VM settings, the effect of this is unclear). I should also mention that, during my freezes, MacOS would have the spinning beachball and become mostly unresponsive.

I'm using Parallels 16.5.0 build 49183

Theo,
Which VM folder in particular should i be disabling in Spotlight? I did find a folder with the windows 10.pvm file in it that i added but i am not sure if this was the correct folder that you mentioned?
