A page file can significantly impact the way your Windows operating system performs. If you adjust the page file in Windows 10 correctly, you can ensure that you are getting the best performance that your hard drive and other components can deliver.
There are other factors that can affect your computer’s performance, but the page file is also an important contributor to this. It’s something that you cannot ignore.
For most circumstances, the default setting of letting Windows handle it is fine. But when you own some older hardware, or you have a unique hard drive configuration, you want something more specific set up.
How to adjust the paging file size
1. Open Advanced System Settings
Right-click on the ‘This PC’ icon on the desktop and left-click on ‘Properties’. Then left-click on ‘Advanced system settings’.
Alternatively, if you don’t have a ‘This PC’ icon on your desktop, hold down the Windows key on your keyboard and tap the ‘R’ key.
Then type ‘sysdm.cpl’ (without the quotes) into the Run box and click on the ‘OK’ button.
Then type in ‘sysdm.cpl’ (without the quotes) and click on the ‘OK’ button.
2. Open Performance Settings
Left-click on the ‘Advanced’ tab then click on on the ‘Settings’ button in the ‘Performance’ box. Next, click on the ‘Advanced’ tab and on the ‘Change’ button in the ‘Virtual memory’ box.
3. Change the virtual memory settings
In order to change the paging file size, you will have to uncheck the ‘Automatically manage paging file size for all drives’ checkbox.
Select the drive that you want to change the paging size for.
You then have the option for selecting a ‘Custom size’ to enter in your own amount, let the system manage the size, or turn the paging file off completely.
If you are choosing to set a custom amount, you need to take your total RAM amount and multiply it by 1.5 (under initial size). Set the maximum size to 3 times your total RAM amount.
You can see how much RAM you have from your ‘System Properties’ window. (Right-click ‘This PC’ icon and left click ‘Properties’.)
What should I set my paging file size to?
One and a half times the total amount of RAM for ‘initial size (MB)’. And 3 times the amount of RAM for ‘Maximum size (MB)’.
How do I reduce page file size?
Follow the steps above to add a custom amount that you want if the automatic amounts are too high.
Out of all the various reasons you want to change your page file amount, achieving something that works well might involve some trial and error.
But in my experience, the system default has worked fine in most cases. So consider carefully the reason you might have for changing it.
