How to fix error error-too-many-names in Windows 11

Solution Steps

1. 1 Press Ctrl + Shift + Esc to open Task Manager. Go to the 'Processes' tab and look for any program that is using a high number of 'Handles' (you may need to add that column by right-clicking the column headers). If you see a program with an unusually high handle count, right-click it and select 'End task'. This frees up the system's name table.
2. 2 Restart your computer. This is the simplest fix — it clears all temporary file handles and resets the system. Save your work and restart.
3. 3 If the error occurs in a specific application, try updating or reinstalling that application. The app may have a memory leak that causes it to hold onto file handles unnecessarily.
4. 4 Check for malware. Run a full system scan with Windows Defender: press Windows key + I, go to Privacy & Security → Windows Security → Virus & threat protection → Scan options → Full scan. Malware can cause handle leaks.
5. 5 If you are a developer, check your code for file handle leaks. Ensure you are closing files and network connections properly. Use tools like Process Explorer to monitor handle usage.
