How To Fix Windows 10 Slow Performance

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

  • Now click Set and then hit OK to save the settings.
  • Reboot the computer for the changes to take effect and fix the Windows 10 slow performance.

Leave your feedback in the comments if this showed improvement for you or not.

If you experience worse performance, you can go back into this setting and change it back to System Managed Size

Option 2: How To Fix Windows 10 Slow Performance

This tip is an oldie but goodie. These settings have been around since Windows XP, but you can still apply them to Windows 10. These will help visually speed things up in Windows 10, especially if you have an older video card or a machine with less RAM. You can read the article Tech Tip: Visually Speed Up Windows 8 (7/Vista/XP).


  • Search for your Control Panel
  • Click on System
  • Click on Advanced System Settings in the left column
  • Under the Advanced tab, click on Settings in the Performance box

I always uncheck the following:

  • Animate windows when minimizing and maximizing
  • Animations in the taskbar
  • Enable Peek (sometimes I leave this one on)
  • Fade or slide menus into view
  • Fade or slide ToolTips into view
  • Fade out menu items after click
  • Slide open combo boxes

      How much RAM does your computer have? It could be related to that and the way Windows 10 calculates its needs.

        • Robert Russell September 24, 2015 at 7:49 am - Reply

          Does the shutdown process just hang and get stuck? If so, how long have you waited for it to complete. Sounds like you could have an app or service getting hung at shutdown.

          Try changing value to 5120 that seems to be the sweet spot for most computers worked for me when 2999 and 3500 weren’t working. Just make sure you have atleast 16 gigs of ram and alot of storage space.

    100 % proved…

    Mostly Speed is also Dependable on Video drivers for example if u have ATI Display Adapter or any other card, Windows 7,8 and 10 installs automatically Standard VGA Adapter Driver that defects the speed of Visual Memory and Virtual Memory Also … Re-install using compatible drivers of matching card specification or model number only …

      ..but, he does highlight the recommended size in the image he has. It’s on your virtual memory page – says “recommended.”

    • Robert Russell July 31, 2015 at 10:17 am - Reply

      If you look at the picture above, you’ll see where it shows the Windows recommended value. It varies on every computer based on specs and RAM. Take that value from the bottom section and type that into the box for Initial Size and Maximum Size. Click the Set button, then click OK and restart your computer.

      • Ben October 25, 2016 at 7:19 pm - Reply

        you should make this more clear. I wasn’t sure if recommended should be put in both boxes until I scrolled and read this comment, knowing someone would ask it as I was also not sure.

          Appreciate the tip though, I’ll update you on how it works out. I found your article looking for a solution to file explorer being extremely slow since updating my work computer from Windows 7 to Windows 10. Super frustrating and wastes so much time. Hopefully this works. Do you have any recommendations for this issue?

    • Stephanie August 11, 2015 at 1:20 pm - Reply

      On the very bottom of that box, directly underneath the space where you type it in, it will say something like “current”
      “recommended” . And it shows what it is recommended to be.

        It really works…just take your time and READ the steps.

        Yes but prior before this task is the paging file size is “system managed” so the question is how do users find the right value for their pc

        • Robert Russell August 7, 2015 at 7:49 am - Reply

          Read the instructions and look at the screenshots. You’ll see a recommended size and you need to set that as the min and max.

          • simon August 18, 2015 at 10:51 pm

            Ok, I am obviously blind. I see it now, thanks

        • Robert Russell August 8, 2015 at 7:15 am - Reply

          When it is set to System Managed it will show you the recommended value in the bottom area like the picture above. Write that number down, then change the setting and type that number into the min and max values.

    Ahhh…what is this for??…i did try it…it improves the processing speed and what not but still the lagging part drives me nuts…like the startup…or even clicking the start menu for the first time…thanks

    • Robert Russell August 4, 2015 at 11:56 am - Reply

      This just helps general speed for me. Other factors would be your video card and processor. Another thing to check is how many programs you have starting up when your computer boots. Windows 10 does delayed startup for non-essential apps, which could cause a delay if you’re trying to open the start menu right away and apps are trying to start in the background.

    • Matt August 16, 2015 at 3:41 pm - Reply

      Google Chrome:
      You can just enter chrome://settings/fonts into your browser and hit “Enter." Now you can change all your font settings.

      Internet Explorer:
      Press the small gear on the top right corner of your browser, then click on the “Internet Options" button.
      On the General tab of the dialog window that pops up, look to the bottom of the popup window and select “Fonts."
      Change your webpage and plain text fonts as desired.

        One other trick that works if you only need to enlarge the display for a single web page, and this trick appears to work on all browsers.

        Hold down the ALT key and press the numeric-keypad plus key, and this will increase the display size for everything on this page. ALT- will shrink all text on this web page.

    I have changed performance settings as suggested. I wasn’t having a problem booting up but two websites i access often were very slow so maybe it was their sites not windows 10. One was banking the other a genealogy site. My pc although new not fast, a mid range laptop and download speeds very slow in France so I expect that, but seemed slowere since upgrade to 10. Anything else I can do?
    Satisfied with you advice by the way.

When I into the process the little boxes (custom size) were blank. There was no instruction on where to find the numbers.

    Please help me… or I am going back to windows 8.0!!!! at least that worked for me!!!!
