windows 10 slow

If you’ve been running the Windows 10 on your computer, even with the newest hardware, you might notice that the operating system seems to slow down or lag at times where menus open slowly or sporadic mouse and keyboard movement. The fixes below have had good reports of fixing Windows 10 slow performance.

While searching around for some tweaks, I came across a thread on the Microsoft Community forums and one suggestion was to change the settings for the Paging File to fix Windows 10 slow performance. By default, in all versions of Windows, it is set to allow the system to manage it.

How To Fix Windows 10 Slow Performance

If you’re noticing slow performance in Windows 10, try changing the Initial Size and Maximum Size to the Recommended File Size for both.

  • Click on Start and type “Performance” and click on “Adjust the appearance and performance of Windows” (as seen in the image above)
  • Go to the Advanced tab and click on Change in the Virtual Memory section.

  • Now uncheck the option Automatically manage paging file size for all drives.
  • Select the C: drive where Windows 10 is installed and then choose Custom Size. If you have a 2nd hard drive, then disable the Page File on your C: drive and enable it on your 2nd drive and set that one to Custom Size. Then change Initial Size and Maximum Size to the Recommended Values by Windows which is in the Total Paging File Size For All Drives section.
  • NOTE: Your recommended value will be different than the image below, use whatever your’s shows
