The [user32:sysparams patterns page](https://test.winehq.org/data/patterns.html#user32:sysparams) shows plenty of failures with Windows 10. Running [a single machine](https://testbot.winehq.org/JobDetails.pl?Key=151682) test did not show such a failure. Therefore the idea is there is some race condition, which shows up when testbot has more load, like in the batch runs. While there was still a batch run active, [I received with a null change](https://testbot.winehq.org/JobDetails.pl?Key=151697) the failures quite reliable. [Adding some Sleeps](https://testbot.winehq.org/JobDetails.pl?Key=151698) seems to improve the situation. This Sleeps would add 4 seconds to each test run. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7522
