How to fix error error-sharing-buffer-exceeded in Windows 11

Solution Steps

1. 1 First, restart your PC. This clears all memory and resets all shared buffers. It's like clearing the whiteboard so everyone can start fresh. If the error only happens occasionally, a restart might be all you need.
2. 2 Check for memory leaks. Press Ctrl+Shift+Esc to open Task Manager. Go to the 'Processes' tab and click 'Memory' to sort by memory usage. Look for any program that's using an unusually large amount of memory (like 2 GB or more) that you didn't expect. If you find one, right-click it and select 'End task'. This frees up the memory it was using. If the program is essential, consider updating it or reinstalling it.
3. 3 Increase the virtual memory (pagefile). Press Windows key + R, type 'sysdm.cpl', and press Enter. Go to the 'Advanced' tab, click 'Settings' under Performance, then go to the 'Advanced' tab again and click 'Change' under Virtual memory. Uncheck 'Automatically manage paging file size for all drives', select your system drive (C:), choose 'Custom size', and set Initial size to 4096 MB and Maximum size to 8192 MB. Click Set, then OK, and restart. This gives Windows more 'overflow' space for memory, reducing the chance of buffer exhaustion.
4. 4 Run a system file check. Open Command Prompt as administrator (Windows key + R, type 'cmd', press Ctrl+Shift+Enter). Type 'sfc /scannow' and press Enter. This repairs corrupted system files that might be causing memory issues. Wait for it to complete.
5. 5 If the error persists, check for malware. Run a full scan with Windows Defender (Settings → Privacy & Security → Windows Security → Virus & threat protection → Scan options → Full scan). Malware can cause memory leaks and buffer overflows.
