Error Code error-max-thrds-reached — Windows 11

Postup řešení

1. 1 First, check if the error is from a specific application. Open Task Manager (Ctrl+Shift+Esc) and go to the 'Details' tab. Look for the process that is using a high number of threads (you can add the 'Threads' column by right-clicking the column headers). If you see a process with thousands of threads, it's likely the culprit.
2. 2 If the application is misbehaving, end it and restart it. Right-click the process and select 'End task'. This frees up the threads. If the error persists, the application may have a bug — check for updates or reinstall it.
3. 3 Increase the system's thread limit. Press Win+R, type 'regedit', and press Enter. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems. Find the 'Windows' value, which contains a string like '%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,768 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16'. Increase the 'MaxRequestThreads' value to a higher number, like 32 or 64. Be careful — this is a system-critical setting.
4. 4 Alternatively, you can reduce the number of threads an application uses. Many applications have settings to limit thread usage. For example, in video editing software, look for 'Thread count' or 'Multithreading' options and reduce them.
5. 5 Run a memory diagnostic to check for RAM issues, as memory leaks can cause thread exhaustion. Press Win+R, type 'mdsched.exe', and press Enter. Choose to restart now and check for problems.
