Reinstall/Update Your Mouse Driver

A device driver is software that informs the operating system and other software how to interact with particular hardware. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers.

If the appropriate driver is not installed, the device might not function properly, if at all. A fault with your mouse driver might cause problems with lag. Try your mouse on another computer to see if you can repeat the problem. If not, then you probably have a faulty driver, and that requires re-installation.

To do so, type "device manager" in Search and click the "Device Manager" result to open it.

reinstall/update your mouse driver step 1

In Device Manager, find "Mice and other pointing devices," expand it, and right-click on your mouse, select "Uninstall" from the drop-down menu to uninstall it. Restart the computer, and Windows will automatically install the missing driver.

You can also try updating your mouse driver. When right-clicked on your mouse in the Device Manager window, repeat the steps and select "Update driver" from the drop-down menu. You will be asked if you want to search for updated driver software automatically or to browse your computer for driver software. If you select the first option, Windows will search your computer and the Internet for the latest driver software for your device.

If you select to browse your computer for driver software, you need to have the correct driver on your computer or USB drive. You can find the driver on your mouse manufacturer's website.

Another way to update or install a new driver for your mouse is by using third-party software such as Snappy Driver Installer. You will need a computer with a working internet connection to download it.

Snappy Driver Installer (SDI) is a powerful free driver updater tool for Windows that can store its entire collection of drivers offline. Having offline drivers gives Snappy Driver Installer the ability to have access to fast driver updates, even if there is no active internet connection. Snappy Driver works with 32-bit and 64-bit versions of Windows 10, Windows 8, Windows 7, Windows Vista, and XP.

Drivers are downloaded through Snappy Driver Installer in driverpacks, which are collections (packs) of drivers for various hardware like sound devices, video cards, network adapters, etc. It can also show duplicate and invalid drivers, and it separates the updates that require you to restart your computer so it would be easier to distinguish them from the rest. You can download Snappy Driver Installer from here.

Disable/Enable Scroll Inactive Windows Feature

One of the native features of Windows 10 is the ability to scroll inactive windows by simply hovering over such a window with the mouse pointer and then using the mouse wheel. The contents of the inactive window will be scrolled.

For example, if you have an inactive Notepad window containing text, that text will be scrolled. The focus will not change and remain in the currently active window. Disabling this feature (and re-enabling, if needed) might help to fix the mouse lag issue.

To disable/enable this feature go to Settings and click "Devices."

In Devices settings, click "Mouse" (or "Mouse & touchpad") on the left pane and then try disabling and enabling the "Scroll inactive windows when I hover them" feature a few times and check if the issue is resolved.

End Realtek Audio Process

Disable Fast Startup

Fast startup is a feature on Windows 10 (and also Windows 8) that provides a faster boot time when starting up your computer. It is a useful feature and one that most people use without knowing.

However, some people disable it immediately when they receive a new computer with the Windows operating system. With the fast startup feature enabled, shutting down your computer might seem like you are completely shutting it down, but this is not entirely true since it moves into a state between hibernation and shutdown. Leaving fast startup enabled should not harm your PC since it is a Windows feature, but this could be why the mouse is lagging.

To fix the problem, you could disable this feature to see if it helps. To disable this feature, go to Search and type "control panel." Click on the "Control Panel" result to open it.

disable fast startup step 1

In Control Panel, set "View by:" to "Small icons," find "Power options," and click it.

disable fast startup step 2

In the Power Options window, click "Choose what the power button does."

disable fast startup step 3

Click on "Change settings that are currently unavailable" and then uncheck the "Turn on fast startup (recommended)" option if it is enabled. Click "Save changes" to save the changes made. Your mouse should start working normally again.

Disconnect Other USB Devices

Another solution that might help is to disconnect any other devices from USB ports. Often, other USB devices can interfere with the mouse and cause a lag issue. Try disconnecting your portable hard drive from the USB port if one is connected (you do not need to disconnect your keyboard).

There are different USB port types. For example, USB 2.0 and USB 1.0 differ in the data transfer rate they are capable of. The maximum speed that USB 1.0 devices can achieve is 12Mbps, while 2.0 devices can theoretically achieve up to 40 times more. If you are using a wireless mouse, try connecting its receiver to the USB 2.0 port.
