滞后，即行动与相应反应/结果之间的延迟，可能会像感恩节时的岳母一样令人讨厌。也许更多。根据一些用户的说法，最近的Windows更新导致鼠标极度滞后和死机。众所周知，鼠标是用户与个人计算机交互的主要设备。当然，有许多快捷键和技巧可以仅使用键盘绕过计算机，但某些事情（例如游戏）在很大程度上依赖于鼠标的输入。想象一下(Imagine)移动鼠标并在光标实际移动到屏幕上所需位置之前必须等待几秒钟！多么令人气愤，对吧？老鼠(Mouse)滞后会严重破坏一个人的游戏体验，影响他们的工作速度，让人沮丧地拔头发等等。
鼠标滞后的原因有很多。最明显的是损坏或过时的驱动程序文件，可以很容易地用新副本替换。来自鼠标相关功能的干扰，例如非活动滚动或错误配置的设置（手掌检查阈值和触摸板延迟）也可能导致延迟。一些报告表明，Realtek Audio进程和Cortana助手可能是罪魁祸首，禁用它们可以摆脱有线或蓝牙鼠标延迟(bluetooth mouse lag)。下面详细介绍了修复鼠标滞后的所有潜在解决方案，供您参考。
在 Windows 10 上修复鼠标延迟的 6 种方法(6 Ways to Fix Mouse Lag on Windows 10)
我们通过将鼠标驱动程序更新到最新版本，然后确保正确配置鼠标并禁用不必要的功能来开始我们对无延迟世界的追求。希望(Hopefully)这些调整可以解决任何延迟问题，但如果没有，我们可以尝试禁用 NVIDIA 的高清音频(High Definition Audio)处理和Cortana助手。
在继续之前，请尝试简单地将鼠标插入另一个USB端口（最好是USB 2.0端口，因为并非所有鼠标都与USB 3.0端口兼容）并移除任何其他连接的设备，因为它们（外部硬盘驱动器）可能会干扰鼠标。您还可以将鼠标完全连接到另一台计算机，以确保设备本身没有故障。如果您使用的是无线鼠标，请将旧电池换成新电池，并检查有线电池是否有磨损或撕裂。
如果您有无线鼠标，您应该检查的另一件事是它的频率/ DPI值。降低相关应用程序的频率并检查是否可以解决延迟问题。如果硬件方面没有问题，请继续使用以下软件解决方案。
如何修复鼠标在Windows 10上的滞后、冻结和跳跃问题？
您可以使用下面列出的方法来解决和修复Windows 10 鼠标滞后(Mouse Lag)问题。确保在继续之前创建一个还原点。(create a restore point)
方法 1：更新鼠标驱动程序以修复鼠标延迟(Method 1: Update Mouse Drivers to fix Mouse Lag)
除非您一直生活在困境中，否则您一定非常熟悉设备驱动程序文件及其在计算中的重要性。查看什么是设备驱动程序？它是如何工作的？(What is a Device Driver? How Does It Work?)在这个话题上启发自己。使用内置的设备管理器(Device Manager)来更新驱动程序将非常有效，但如果您希望为此目的使用专门的应用程序，请继续安装Driver Booster。
1. 按Windows key + R打开“运行”命令框(Run command box)，然后键入devmgmt.msc 并单击“确定(OK)”打开设备管理器(Device Manager)。
2.展开鼠标和其他指针设备(Expand Mice and other pointing devices )，然后 右键单击(Right-click) 并从随后的选项中选择属性。(Properties )
3. 切换到驱动程序(Driver )选项卡，如果可用，单击回滚驱动程序(Roll Back Driver)按钮。如果没有，请单击卸载设备(Uninstall Device)选项。通过在以下弹出窗口中再次单击“卸载”按钮来确认您的操作。(Uninstall)
4. 现在，单击扫描硬件更改(Scan for the hardware changes)按钮。
5. 要让Windows自动安装最新的鼠标驱动程序，只需重新启动计算机(restart your computer)或单击更新驱动程序(Update Driver)选项。
6. 选择自动搜索驱动程序(Search automatically for drivers)。
更新驱动程序后，检查鼠标是否继续滞后。
方法 2：禁用滚动非活动窗口(Method 2: Disable Scroll Inactive Windows)
在Windows 8上，如果不先突出显示/选择它，就无法滚动应用程序窗口。快(Fast)进到Windows 10时，微软(Microsoft)推出了一项名为“滚动非活动窗口(Scroll Inactive Windows)”的新功能，用户只需将鼠标指针悬停在非活动应用程序窗口上即可滚动浏览它。例如 – 如果您打开了Word文档和Chrome网页以供参考，您只需将鼠标悬停在Chrome窗口上并滚动即可。但是当Chrome 滚动条在 Windows 10 中消失(Chrome Scrollbar Disappears in Windows 10? )时你会怎么做？ 因此，该功能可以避免切换活动Windows的麻烦(Windows)每隔几秒钟。但是，该功能已与多个鼠标问题相关联，禁用它可以阻止所有这些问题。
1. 按Windows key + I 启动Windows 设置( Windows Settings )，然后单击设备(Devices)。
2. 移至Mouse & Touchpad设置页面（或仅Mouse，取决于您的Windows版本）并在我将鼠标悬停在 Scroll inactive Windows 下方时(Scroll inactive Windows when I hover over them.)关闭(toggle off )开关。
如果禁用不能立即解决问题，请尝试启用和禁用该功能几次，并检查它是否修复了滞后的鼠标。

方法 3：更改触摸板延迟和手掌检查阈值(Method 3: Change Touchpad Delay and Palm Check Threshold)
为避免用户在键入时意外移动指针，触摸板会自动禁用。触摸板仅在最后一次按键后稍微延迟后重新启用，这种延迟称为触摸板延迟(Touchpad Delay)（呃！）。将延迟设置为较低的值或完全为零可以帮助您消除任何触摸板滞后。（注意：触摸板(Touchpad)延迟功能是特定于驱动程序的，可能在您的笔记本电脑上使用不同的名称。）
1. 按Windows key + I 启动Windows 设置( Windows Settings )，然后单击设备(Devices)。
2. 展开Touchpad(Touchpad)部分下的下拉列表，然后选择No delay (always on)。
注意： (Note: )如果您使用的是最新的Windows版本，只需将触摸板灵敏度(Touchpad sensitivity)设置为“最敏感(Most sensitive)”。
另一个避免意外触摸板点击的类似功能是手掌检查阈值。将阈值降低到最小值有助于消除鼠标延迟。 (Another similar feature to avoid accidental touchpad taps is Palm Check Threshold. Lowering the threshold value to the minimum can be helpful in getting rid of mouse lag. )
1.再次打开鼠标设置并单击(Mouse Settings)附加鼠标选项(Additional mouse options)。
2. 切换到触摸板(Touchpad)（或点击(Clickpad)板）选项卡并单击属性(Properties)按钮。
3. 手掌检查阈值选项最有可能列在“高级”选项卡( Advanced tab)上。切换到它并将滑块一直拖到左侧。 (Switch to it and drag the slider all the way to the left. )
方法 4：终止并禁用 Realtek 音频 (Method 4: Terminate & Disable Realtek Audio )
似乎适用于多个用户的一个相当奇怪的修复是禁用Realtek HD Audio Manager进程。来自Realtek(Realtek)进程的干扰可能会导致延迟，如果确实如此，只需终止进程即可解决问题。
1. 同时按下Ctrl+Shift+Esc键启动Windows 任务管理器( Windows Task Manager)。如果需要，单击更多详细信息(More Details)以展开应用程序窗口。
2. 在进程选项卡上，找到Realtek HD Audio Manager 进程，( Realtek HD Audio Manager process,) 选择它，然后单击右下角的结束任务(End Task)按钮。
3. 现在，检查鼠标是否继续滞后。如果是，请打开设备管理器(open the Device Manager)（方法 1 的第 1 步）并展开声音、视频和游戏控制器。 ( expand Sound, video and game controllers. )
4.右键单击 Realtek High Definition Audio(Right-click on Realtek High Definition Audio)并选择禁用设备(Disable device)。

方法 5：禁用 Cortana 助手 (Method 5: Disable Cortana Assistant )
与上一个类似，另一个可能会干扰您的鼠标的不相关功能是Cortana 助手(Cortana Assistant)。如果您很少使用Cortana，那么禁用它可以帮助您释放一些系统内存并帮助提高性能并解决任何鼠标滞后问题。
1. 通过在运行命令框中(Run command box )键入regedit打开注册表编辑器(Registry Editor)，然后按 Enter。
2.使用左侧的侧边栏沿着下面的路径前进，或者简单地将路径复制粘贴到顶部的地址栏中：(Head)
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search
注意：有些用户可能在(Note:)Windows文件夹下找不到Windows Search键，只需右键单击 Windows( right-click on Windows)，选择New后跟Key，并将新创建的键命名为Windows Search。
3. 如果AllowCortana值已经存在于右侧面板中，双击以更改其属性并将值数据设置为 0。(double-click to change its properties and set the Value data to 0.)如果该值不存在，右键单击(right-click)任意位置并选择New > DWord (32-bit) Value，将Value 数据(Value data )设置为0以禁用 Cortana。
4. 重新启动计算机(Restart your computer)并检查延迟是否已解决。
方法 6：更改电源管理设置(Method 6: Change Power Management Settings)
另一个经常被忽视的设置是您的计算机尝试节省电量的积极程度。计算机通常会禁用USB端口以试图节省电量，这反过来会导致您在一段时间后移动鼠标时出现轻微的延迟/滞后。禁止计算机禁用与鼠标连接的USB端口可以帮助解决延迟问题。
1.按照方法一的步骤一打开设备管理器应用程序。( Device Manager)
2. 展开Universal Serial Bus controller并(s)双击USB Device打开它的Properties。
3. 切换到电源管理(Power Management)选项卡并取消选中(untick )允许计算机关闭此设备以节省电源(Allow the computer to turn off this device to save power.)旁边的框。
4. 单击确定(OK)保存并退出。
如果有可用更新，您也可以尝试更新Windows （ Windows Settings > Update和安全 > Windows更新(Updates)Security > Windows Update > Check更新）。

How to Fix Mouse Lag on Windows 10 (Increase Mouse Response Time)
Lag, the delay between an action and the corresponding reaction/result, can be as annоyіng as your mother-in-law at thanksgіving. Maybe even more. According to some uѕers, a recent Windоws υpdate is causing extreme mouse lags and freezes. As evеryone already knows, a mouse is a primary dеvicе via which users interact with their personal computers. Of course, there are a number of key shortcuts and tricks to get around the computer using only thе kеyboard but some things such as gaming heavily depend on inputs from the mouse. Imagine movіng the mouѕe and having to wait a couple of seconds before the cursor actually travels to the required position on the screen! How infuriating, right? Mouse lags cаn severely ruin one’s gaming exрerience, take a toll on their working speed, make one pull theіr hair out in frustration, etc.
There are a plethora of reasons why your mouse may be lagging. The most obvious being corrupt or outdated driver files which can easily be replaced with a fresh copy. Interference from mouse-related features such as inactive scrolling or misconfigured settings (palm check threshold and touchpad delay) can also cause lag. Some reports suggest that the Realtek Audio process and Cortana assistant may be the culprits and disabling them can get rid of the wired or bluetooth mouse lag. All the potential solutions to fix a laggy mouse are detailed below for you to follow.
6 Ways to Fix Mouse Lag on Windows 10
We start our quest to a lag-free world by updating the mouse drivers to the latest version followed by ensuring the mouse is properly configured and unnecessary features are disabled. Hopefully, these tweaks will fix any lag but if they don’t, we can try disabling NVIDIA’s High Definition Audio process and Cortana assistant.
Before moving ahead, try simply plugging the mouse into another USB port (preferably a USB 2.0 port since not all mice are compatible with USB 3.0 ports) and removing any other connected devices as they (external hard drive) may interfere with the mouse. You can also connect the mouse to another computer altogether to ensure the device itself isn’t at fault. If you are using a wireless mouse, switch the old batteries for a new pair and check for any frays or tears in wired ones.
Another thing you should check if you have a wireless mouse is its frequency/DPI value. Lower down the frequency from the associated application and check if that resolves the lag. If nothing is wrong with the hardware side of things, move on to the below software solutions.
How do I fix my mouse from lagging, freezing, and jumping on Windows 10?
You can use the below-listed methods to troubleshoot and fix Windows 10 Mouse Lag issues. Make sure to create a restore point before you continue.
Method 1: Update Mouse Drivers to fix Mouse Lag
Unless you have been living under a rock, you must be all too familiar with device driver files and their importance in computing. Check out What is a Device Driver? How Does It Work? to enlighten yourself on the topic. Using the built-in Device Manager to update drivers will very well do the trick but if you wish to use a specialized application for this purpose, go ahead and install Driver Booster.
1. Press Windows key + R to open the Run command box then type devmgmt.msc and click on OK to open the Device Manager.
2. Expand Mice and other pointing devices then Right-click and select Properties from the ensuing options.
3. Switch to the Driver tab and click on the Roll Back Driver button if available. If not, then click on Uninstall Device option. Confirm your action by clicking on the Uninstall button again in the following pop-up.
4. Now, Click on the Scan for the hardware changes button.
5. To have Windows automatically install the latest mouse drivers, simply restart your computer or click on the Update Driver option.
6. Select Search automatically for drivers.
Once the drivers have been updated, check if your mouse continues to lag.
Method 2: Disable Scroll Inactive Windows
On Windows 8, one could not scroll through an application window without first highlighting/selecting it. Fast forward to Windows 10, Microsoft introduced a new feature called ‘Scroll Inactive Windows’ which lets users scroll through an inactive application window by simply hovering the mouse pointer over it. For example – If you have a Word document and a Chrome webpage open for reference, you can simply hover the mouse over the Chrome window and scroll. But what do you do when Chrome Scrollbar Disappears in Windows 10? Thus, the feature prevents the hassle of switching active Windows every few seconds. However, the feature has been linked to multiple mouse issues, and disabling it can put a stop to all of them.
1. Press the Windows key + I to launch Windows Settings then click on Devices.
2. Move to the Mouse & Touchpad settings page (or only Mouse, depending on your Windows version) and toggle off the switch under Scroll inactive Windows when I hover over them.
If disabling doesn’t fix the issue instantly, try enabling and disabling the feature a couple of times and check if it fixes the laggy mouse.

Method 3: Change Touchpad Delay and Palm Check Threshold
To avoid users from accidentally moving the pointer while they type, the touchpad is automatically disabled. The touchpad only gets re-enabled after the last keypress with a slight delay and this delay is known as Touchpad Delay (duh!). Setting the delay to a lower value or to zero altogether can help you negate any touchpad lags. (Note: The Touchpad delay feature is driver-specific and may bear a different name on your laptop.)
1. Press the Windows key + I to launch Windows Settings then click on Devices.
2. Expand the drop-down list under the Touchpad section and select No delay (always on).
Note: If you are on the latest Windows build, simply set the Touchpad sensitivity to ‘Most sensitive’.
Another similar feature to avoid accidental touchpad taps is Palm Check Threshold. Lowering the threshold value to the minimum can be helpful in getting rid of mouse lag.
1. Open Mouse Settings once again and click on Additional mouse options.
2. Switch to Touchpad (or Clickpad) tab and click on the Properties button.
3. The palm check threshold option is most likely to be listed on the Advanced tab. Switch to it and drag the slider all the way to the left.
Method 4: Terminate & Disable Realtek Audio
A rather odd fix that seems to be working for multiple users is disabling the Realtek HD Audio Manager process. Interference from the Realtek process may be causing the lag and if that is indeed the case, simply terminating the process should resolve the issue.
1. Press the Ctrl+Shift+Esc keys simultaneously to launch the Windows Task Manager. If required, click on More Details to expand the application window.
2. On the Processes tab, locate the Realtek HD Audio Manager process, select it and then click on the End Task button at the bottom right.
3. Now, check if the mouse continues to lag. If yes, open the Device Manager (Step 1 of Method 1) and expand Sound, video and game controllers.
4. Right-click on Realtek High Definition Audio and select Disable device.

Method 5: Disable Cortana Assistant
Similar to the last one, yet another unrelated feature that may be interfering with your mouse is the Cortana Assistant. If you seldom use Cortana then disabling it can help you free up some system memory and help boost performance along with solving any mouse lags.
1. Open the Registry Editor by typing regedit in the Run command box and press enter.
2. Head down the below path using the sidebar on the left or simply copy-paste the path in the address bar on the top:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search
Note: Some users may not find the Windows Search key under the Windows folder, simply right-click on Windows, select New followed by Key, and name the newly created key as Windows Search.
3. If an AllowCortana value is already present on the right-panel, double-click to change its properties and set the Value data to 0. If the value isn’t present, right-click anywhere and select New > DWord (32-bit) Value, set the Value data to 0 to disable Cortana.
4. Restart your computer and check if the lag has been resolved.
Method 6: Change Power Management Settings
Another setting that is often overlooked is how aggressively your computer is trying to save power. Computers often disable USB ports in an attempt to save power which in turn results in a slight delay/lag when you move the mouse after a little while. Prohibiting the computer from disabling the USB port to which the mouse is connected can help with the lag.
1. Open the Device Manager application by following step 1 of method 1.
2. Expand Universal Serial Bus controllers and double-click on the USB Device to open its Properties.
3. Switch to the Power Management tab and untick the box next to Allow the computer to turn off this device to save power.
4. Click on OK to save and exit.
You can also try updating Windows if there is an update available (Windows Settings > Update & Security > Windows Update > Check for Updates).
