Everytime I start the Windows 10 VM, I get that message "performance may be affected as windows is installing updates". It is beyond irritating! As I don't care if that VM gets hacked by half of the planet, I would like to know if there is a way to disable updates forever? I don't think it is really installing updates all the time, so I wonder if that message appears even when it is looking for updates, or if an update fails and it tries to install it over and over. Any idea?
The same thing occurs here too. Because it's daily i have the the strong feeling it has to do with Windows defender ( getting it's daily updates)
+1 Instead of stopping the update process, wouldn't it be a better solution to detect that the update is for Windows Defender update vs. other Windows updates? If that's not the case, then possibly a timer if the update is taking up X resouces for Y time, then display the notification?

I have installed build 11.2.0 (32581) of Parallels desktop and I get "Performance may be affected while....." message every time I start and run the Windows 10 VM too. I check the Windows update applet and it is not updating and all updates are installed. Any ideas for a fix?
Hi RobertS15, Windows updates may slow down your Windows virtual machine performance. Go to Actions > Configure > Options > Optimization > disable Free Space: Real-time Virtual Disk Optimization. If the "Real-time Virtual Disk Optimization" option is enabled, it may slow disk performance up to 30% (at the moment of compaction, not constantly). If the host has an SSD disk, the feature will be enabled by default for all virtual machines but will work only if it is compatible with the guest OS. Open virtual machine configuration > switch to Options tab > Optimization tab > Set performance to Faster virtual machine; check Enable adaptive hypervisor and Tune Windows for speed. If you're not running on battery power, you can also turn on the Better performance option.
