How to Set Appropriate Virtual Memory Pagefile Size in Windows PC

This guide explains how to optimize virtual memory settings in Windows for improved performance. Contrary to common advice suggesting setting the page file size to 1.5 or 2 times your RAM, letting Windows manage this automatically is generally best. This approach avoids potential performance issues caused by excessively large or small page files.

Why let Windows manage your page file?

1. Overly large page files unnecessarily burden your hard drive, slowing down overall system performance, especially startup and shutdown times.
2. Conversely, a page file that's too small can lead to system instability and crashes.
3. Windows optimally manages the page file on your primary drive. If you frequently use your page file, adding more RAM is a more effective solution than increasing the page file size.

How to configure Windows to manage your page file:

Step 1: Access System Properties:

Press Win R, type control sysdm.cpl, and press Enter.

Alternatively, press Windows Pause Break, click "Advanced system settings" in the left pane of the System window.

Step 2: Open Performance Settings:

In the System Properties window, go to the Advanced tab. Under Performance, click Settings.

Step 3: Access Virtual Memory Settings:

Click the Advanced tab again, then click the Change button in the "Virtual memory" section.

Step 4: Enable Automatic Page File Management:

Uncheck "Automatically manage paging file size for all drives". Select your primary drive (usually C:), choose "System managed size", and click Set. Click OK to save changes.

Step 5: Restart Your Computer:

Restart your computer for the changes to take effect.
