Managing virtual memory in Windows 11 can help optimize system performance or free up disk space. This guide explains how to enable, adjust, or disable virtual memory step by step.
What is Virtual Memory?
Virtual memory, also known as a paging file, allows Windows 11 to use part of your storage drive (SSD or HDD) as additional RAM. When physical memory is full, virtual memory ensures programs continue running. However, because storage drives are slower than RAM, performance may be affected. Adjusting virtual memory can improve stability in certain cases, while disabling it may save disk space but risks performance issues during memory‑intensive tasks.
How to Enable or Adjust Virtual Memory
- Press Windows Key + I to open Settings.
- Navigate to System → About.
- Under Related settings, click Advanced system settings.
- In the System Properties window, go to the Advanced tab.
- Under Performance, click Settings.
- Switch to the Advanced tab in Performance Options and click Change under Virtual memory.
- Uncheck Automatically manage paging file size for all drives.
- Select the drive where you want to enable virtual memory.
- Choose Custom size and enter the Initial size and Maximum size (in MB).
Tip: A common recommendation is 1.5x your RAM for the initial size and 3x for the maximum size. - Click Set and then OK.
- Restart your computer to apply the changes.
How to Disable Virtual Memory
- Follow the same steps above to access Virtual Memory settings.
- Select the drive and choose No paging file.
- Click Set and then OK.
- Restart your PC to apply the changes.
Virtual memory management in Windows 11 gives you control over system performance and storage usage. Adjust settings carefully to balance speed and stability for your specific needs.
