Comment (by dkocher):

 https://docs.microsoft.com/en-us/windows/win32/sysinfo/user-objects

  User interface objects support only one handle per object. Processes
 cannot inherit or duplicate handles to user objects. Processes in one
 session cannot reference a user handle in another session. There is a
 theoretical limit of 65,536 user handles per session. However, the maximum
 number of user handles that can be opened per session is usually lower,
 since it is affected by available memory. There is also a default per-
 process limit of user handles. To change this limit, set the following
 registry value:


 {{{
 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
 NT\CurrentVersion\Windows\USERProcessHandleQuota

 }}}

 This value can be set to a number between 200 and 18,000.
