My Win10 Pro x64 Ru was updated during restart at 2023-08-09.
Yesterday I realized that my tests have a big number of leaked handles :)
After researching, I found out that the problem in tests whose are using MS DTC.
Even one test have for about 100 leaked handles.
This problem in 32bit and in 64bit processes.
Memory does not leak.
I ran this test on outdated Windows 7 - it works OK.
I have the logs those confirm that there were not problems before restart at 2023-08-09.
Is it a known problem?
Here is the properties of my x64 msdtxprx.dll
