屏幕保护程序是系统空闲一段时间后出现在系统屏幕上的移动视觉效果。但是，有时屏幕保护程序可能因各种原因无法启动或停止工作。如果屏幕保护程序在您的Windows系统中(Windows)不起作用(screensaver is not working)，那么本文可能会对您有所帮助。
屏幕保护程序在(Screensaver)Windows 11/10中不起作用
早些时候，CRT 显示器需要屏幕保护程序，因为如果长时间不更换屏幕，显示器背景可能会变色。现代显示器并非如此，但屏幕保护程序对于隐藏信息是必要的。在许多计算机中，默认情况下不会激活屏幕保护程序。在其他情况下，Windows 更新(Windows Updates)可以关闭屏幕保护程序，您需要更改设置。
Windows 11/10中不起作用的问题，请尝试更新 Windows(updating Windows)。如果这没有帮助，请按顺序执行以下解决方案：
- 检查屏幕保护程序设置
- 检查睡眠设置
- 保持鼠标清洁并远离抛光表面
- 拔掉外围设备
- 恢复默认电源设置
- 使用电源疑难解答
- 更新显示或图形驱动程序
- 运行 SFC 扫描。
让我们详细了解它们。
1]检查屏幕保护程序设置
屏幕保护程序很可能已关闭(OFF)。这可能是默认设置，也可能在Windows更新后发生更改。还已知一些第三方程序会更改这些设置。可以按如下方式检查屏幕保护程序设置：
在Windows(Windows)搜索栏中搜索“屏幕保护程序”，然后选择“更改屏幕保护程序(Change screen saver)”选项。这将打开屏幕保护程序设置(Screen Saver Settings)页面。
如果屏幕保护程序设置为<none>，则屏幕保护程序被禁用。在这种情况下，您可以在下拉菜单中将其更改为您选择的任何其他选项。
选择您选择的等待(Wait)时间。
点击应用(Apply)，然后点击确定(OK)以保存设置。
2]检查睡眠设置
如果您的睡眠设置(Sleep settings)设置为在屏幕保护程序激活之前关闭屏幕或睡眠(Sleep)，那么您将永远看不到它。因此，将您的屏幕保护(Screensaver)程序设置为激活，例如 5 分钟，然后将 PC 设置为睡眠(Sleep)（关闭显示时间(Turn off the display time)设置），例如 10 分钟。

3]保持(Keep)鼠标清洁并远离抛光表面
鼠标最轻微的移动也算作系统的移动。如果光学鼠标不干净或放在抛光表面上，它会继续记录动作，因此屏幕保护程序可能不会出现。要隔离这种可能性，请清洁鼠标底部并将其放在白纸上一段时间。如果屏幕保护程序仍未出现，请转到下一个解决方案。
4]拔下外围设备
当连接到系统时，一些外围设备会发送一条消息，指出计算机不需要休息，因为外围设备正在工作。在许多情况下，该指令被编码到驱动程序中。
在这种情况下，您可以尝试拔下所有外围设备并检查屏幕保护程序是否出现。如果是，则将设备一一插回，以确定是哪一个导致了该错误。现在由您决定是否保留外围设备。
5]恢复默认电源(Power)设置
屏幕保护程序由系统的电源设置控制。如果Windows更新或第三方软件弄乱了电源(Power)设置，则屏幕保护程序可能无法正常工作。在这种情况下，您可以将电源设置重置为默认值，如下所示：
Press Win+R打开“运行”(Run)窗口并键入命令powercfg.cpl。按 Enter 打开“电源选项(Power Options)”窗口。
单击与当前电源计划相对应的更改计划设置。(Change plan settings)
选择为此计划恢复默认设置(Restore default settings for this plan)并点击Yes。
这会将电源设置恢复为默认值。检查它是否有助于屏幕保护程序。
6]使用电源故障排除程序
电源疑难解答可以修复与电源(Power)设置相关的问题。运行电源(Power)故障排除程序的过程如下：
在Windows 11中：打开Settings > System > Troubleshoot。
在Windows 10中：转到Settings > Updates和Security > Troubleshoot。
从列表中选择电源疑难解答(Power troubleshooter)并运行它。
重新启动系统并检查它是否可以解决您的屏幕保护程序问题。
7]更新显示(Update Display)或图形(Graphics)驱动程序
更新您的图形驱动程序(Update your Graphics Drivers)，看看它是否有帮助。如果您最近更新了它们，则回滚并查看。否则，您可以下载驱动程序(download the drivers)并重新安装它们。
8]运行SFC扫描
丢失或损坏的系统文件可能会导致讨论中的问题。SFC 扫描有助于检查系统上丢失的文件并在必要时替换它们。

Screensaver not working in Windows 11/10
Screensavers are moving visυals that appear on your system’s screen after the system haѕ been idle for a while. Hоwever, at times the screensаver may not start or may stop working fоr νarious reasonѕ. In case the screensaver is not working in your Windows system, then this article may help you.
Screensaver not working in Windows 11/10
Earlier, screensavers were necessary for CRT monitors since the monitor background could get discolored if the screen wasn’t changed for long. This isn’t the case with modern monitors but screensavers are necessary for hiding information. In many computers, screensavers aren’t activated by default. In other cases, Windows Updates can turn off the screensavers and you need to change the settings.
In case you encounter the issue of screensaver not working in Windows 11/10, try updating Windows. If this doesn’t help, proceed with the following solutions sequentially:
- Check the Screensaver settings
- Check Sleep settings
- Keep your mouse clean and away from polished surfaces
- Unplug the peripherals
- Restore the default Power settings
- Use the Power Troubleshooter
- Update Display or Graphics Drivers
- Run an SFC scan.
Let us see them in detail.
1] Check the Screensaver settings
It is quite possible that the screensaver is turned OFF. This could either be a default setting or could have changed after a Windows update. Some third-party programs are also known to alter these settings. The screensaver settings could be checked as follows:
Search for ‘screen saver’ in the Windows search bar and select the option for Change screen saver. This will open the Screen Saver Settings page.
If the Screen saver is set at <none>, the screen saver is disabled. In this case, you can change it to any other option of your choice in the drop-down menu.
Select the Wait time of your choice.
Hit Apply and then OK to save the settings.
2] Check Sleep settings
If your Sleep settings are set to turn off the screen or Sleep before the screensaver can activate, then you will never see it. So set your Screensaver to activate, say after 5 minutes, and PC to Sleep (Turn off the display time setting) after, say 10 minutes.

3] Keep your mouse clean and away from polished surfaces
The slightest movement of a mouse counts as a movement for the system. If an optical mouse is unclean or kept on a polished surface, it will keep recording movements and thus the screensaver might not appear. To isolate this probability, clean the bottom of the mouse and keep it on white paper for a while. If the screensaver still doesn’t appear, move to the next solution.
4] Unplug the peripherals
When connected to the system, some peripherals send a message that the computer needn’t rest since the peripheral device is at work. In many cases, this instruction is encoded into the drivers.
In this situation, you can try unplugging all the peripherals and check if the screensaver appears. If yes, plug the devices back one by one to figure which one caused the bug. Now it is for you to decide whether or not to keep the peripheral.
5] Restore the default Power settings
The screensaver is governed by the power settings of the system. If a Windows update or third-party software messes up with the Power settings, the screensaver might not work right. In this case, you can reset the Power settings to default as follows:
Press Win+R to open the Run window and type the command powercfg.cpl. Hit Enter to open the Power Options window.
Click on Change plan settings corresponding to your current power plan.
Select Restore default settings for this plan and hit Yes.
This will restore the power settings to default. Check if it helps with the screensaver.
6] Use the Power Troubleshooter
The Power Troubleshooter can fix issues related to the Power settings. The procedure to run the Power troubleshooter is as follows:
In Windows 11: Open Settings > System > Troubleshoot.
In Windows 10: Go to Settings > Updates and Security > Troubleshoot.
Select the Power troubleshooter from the list and run it.
Restart the system and check if it resolves your problem with the screensaver.
7] Update Display or Graphics Drivers
Update your Graphics Drivers and see if it helps. If you recently updated them, then rollback and see. Else you can download the drivers and fresh-install them.
8] Run an SFC scan
Missing or corrupted system files can cause the issue in discussion. The SFC scan help in checking for missing files on the system and replacing them if necessary.
