The method for changing your mouse DPI in Windows 10 depends on whether your mouse has dedicated DPI buttons or not.

If your mouse has dedicated DPI buttons:

  1. Locate the DPI buttons on your mouse. These are typically found on the top or sides of the mouse.
  2. Press one of the DPI buttons to change the DPI setting. The DPI setting will typically cycle through a few different options, such as 800, 1600, and 3200 DPI.

If your mouse does not have dedicated DPI buttons:

  1. Open the Settings app. You can do this by clicking the Start menu and then selecting the Settings icon.
  2. Select Devices.
  3. Select Mouse.
  4. Under “Related settings,” click Additional mouse options.
  5. In the Mouse Properties window, click the Pointer Options tab.
  6. Under “Pointer speed,” move the slider to the desired setting. A higher DPI setting will make your mouse cursor move faster, while a lower DPI setting will make it move slower.
  7. Click OK to apply the changes.
