Windows 11:Excessive RAM Usage - Large Pages Consuming 17GB

If you've recently upgraded to Windows 11 and have noticed that your PC is running slower than usual, with tasks like resizing windows taking longer than they should, you're not alone. Many users have reported similar issues, and in this article, we'll explore one possible cause: excessive RAM usage due to large pages consuming 17GB or more.

What are Large Pages?

Large pages are a feature of modern operating systems that allows applications to allocate memory in large, contiguous blocks. This can improve performance by reducing the amount of overhead required to manage memory. However, if not managed properly, large pages can consume a significant amount of system resources, leading to excessive RAM usage and slower performance.

How to Check for Large Pages in Windows 11

To check for large pages in Windows 11, you can use the Task Manager. Here's how:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click on the Details tab.
3. Right-click on any column header and select Select columns.
4. Check the box next to Large Page and click OK.
5. Sort the list by the Large Page column to see which processes are using large pages.

If you find that large pages are consuming a significant amount of RAM in Windows 11, there are a few steps you can take to reduce their usage:

1. Close any applications that are not currently in use.
2. Restart your PC to clear any unnecessary processes and free up RAM.
3. Adjust the size of the large page allocation by modifying the LargePageMinimum and LargePageSize registry keys.
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "LargePageMinimum"=dword:00010000 "LargePageSize"=dword:00200000
