如果您发现您的 PC 有任何异常，您可能要做的第一件事就是打开Windows 任务管理器(Windows Task Manager)。然后，您可以快速关闭 CPU 密集型应用程序或卡住的进程，让事情再次正常运行。但是，如果你达不到呢？
如果您尝试打开任务管理器(Task Manager)，但它没有显示、崩溃，或者您看到“任务管理器(Task Manager)没有响应”或“任务管理器(Task Manager)已被管理员禁用”消息，您可能遇到了严重的问题需要修复。我们将向您展示如何在Windows 10和 11 中执行此操作。
尝试其他方式打开任务管理器
您有多种方法可以在 Windows 中打开任务管理器(multiple ways to open the Task Manager in Windows)。假设(Suppose)您无法通过高级用户(Power User)菜单或任务栏显示它。在这种情况下，您可能希望通过Ctrl + Alt + Delete屏幕（按Ctrl + Alt + Delete并选择Task Manager）或使用专用的任务管理器(Task Manager)快捷方式（按Ctrl + Shift + Esc）打开它。如果问题仍然存在，是时候开始排除故障了。
提示(Tip)：您是否尝试过重新启动计算机？这听起来很简单，但它确实有助于解决Windows的意外问题。打开开始菜单(Start menu )并选择电源(Power)>重新启动(Restart)以执行系统重新启动。
1.扫描恶意活动
鉴于任务管理器对用户的重要性，计算机病毒经常攻击并禁用它以阻止您与其交互。因此，最好通过扫描您的计算机中的恶意软件来开始。
我们建议您使用Malwarebytes。它在删除恶意软件方面非常有效，而且免费版本足以完成手头的任务。
1. 下载、安装并打开 Malwarebytes。
2. 选择扫描仪(Scanner)。
3. 选择高级扫描仪(Advanced scanners)。
4. 选择配置扫描(Configure scan)。
5. 选择您计算机上的主分区— C。然后，保留其余默认选择并选择Scan。
有时，恶意软件感染可能很普遍，并阻止您安装或使用防病毒实用程序。在这种情况下，请查看我们的从您的 PC 中删除顽固恶意软件(removing stubborn malware from your PC)的指南。
2.检查注册表编辑器
如果您在扫描您的计算机以查找恶意软件的情况下仍看到“任务管理器(Task Manager)已被管理员禁用”错误，请通过下面的注册表(Registry)编辑器相关修复程序运行。
1. 按Windows + R打开运行框。
2.输入regedit并按Enter。
3. 将以下路径复制并粘贴到Windows 注册表编辑器(Windows Registry Editor)窗口的顶部，然后按Enter：
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
4. 选择左侧导航窗格中的系统文件夹。(System)
5. 双击标有 DisableTaskmgr(DisableTaskmgr)的注册表项。
5. 输入值0并选择OK。
如果您在第 5 步中没有看到该注册表项，请尝试自己创建它。右键单击注册表编辑器(Registry Editor)窗口右侧的空白区域，然后选择New > DWORD (32-BIT) Value。然后，将其命名为DisableTaskMgr，并将其设置为值0。
3.检查组策略编辑器
如果任务管理器(Task Manager)的问题仍然存在，您必须检查计算机上的组策略编辑器(Group Policy Editor)并重新配置特定策略。如果您使用Windows 10或 11的家庭(Home)版，请跳过此修复。
1. 打开运行(Run )框。
2.输入gpedit.msc并按Enter。
2. 导航到左侧边栏的以下位置：
用户配置(User Configuration)>管理模板(Administrative Templates)>系统(System)> Ctrl + Alt + Del 选项(Del Options)
3. 右键单击删除任务管理器(Remove Task Manager)策略并选择编辑(Edit)。
4. 选择未配置(Not configured )或禁用(Disabled)。
5. 选择应用( Apply)>确定(OK )以保存您的更改。

4.等待(Wait)系统文件检查器(System File Checker)扫描并解决Windows中的任何完整性违规。
5. 通过运行DISM工具来执行此操作：
DISM.exe /Online /Cleanup-image /Restorehealth
或者，您可以通过命令提示符(Command Prompt)控制台运行这两个命令行工具。在开始菜单(Start menu )中输入cmd并选择以管理员身份运行( Run as administrator)以打开它。
6. 创建新的 Windows 帐户
损坏的Windows用户配置文件还可能导致各种与系统相关的应用程序和服务出现问题。在您的计算机上创建一个新帐户，登录它，然后检查任务管理器(Task Manager)是否照常打开。
1. 打开开始菜单(Start menu)并选择设置(Settings)。
2. 选择账户(Accounts)。
3.选择家庭和其他用户(Family & other users)。
4. 在其他用户(Other users)下，选择添加帐户(Add account)。

6. 选择添加没有 Microsoft 帐户的用户(Add a user without a Microsoft account)。
7. 插入用户名并创建本地帐户。
8. 打开开始菜单(Start menu)，选择您的头像，然后登录新帐户。
9.尝试打开任务管理器(Task Manager)。如果可以，您可以执行以下操作将数据迁移到新用户帐户(migrate your data into the new user account)中。
7.更新操作系统
更新Windows是另一个可以提供帮助的修复程序，特别是如果任务管理器(Task Manager)在启动时冻结或您遇到“任务管理器(Task Manager)没有响应”错误消息。
1. 打开设置(Settings )应用程序。
2. 选择Windows 更新(Windows Update)。
3. 选择检查更新(Check for updates)>下载并安装(Download & install)。
如果您在安装任务管理器(Task Manager)后立即出现问题，您也可以卸载任何最近的 Windows 更新(uninstall any recent Windows updates)。
8. 恢复窗口
如果上述修复都没有帮助，您可以选择将Windows还原到较早的状态。但是，这只有在您已经设置了系统还原的情况下才有可能。(System Restore)
1. 打开开始菜单(Start menu)，在搜索框中输入系统保护，然后( System Protection)回车(Enter)。
2. 在系统保护(System Protection)选项卡下，选择系统还原(System Restore)。
3. 选择下一步(Next)。
4.从您打开任务管理器(Task Manager)没有问题的时候选择一个还原点。
5. 选择完成(Finish)。
9.恢复出厂设置窗口
如果您的计算机上未启用系统还原，请考虑(System Restore)将 Windows 重置为出厂默认设置(resetting Windows to factory defaults)。尽管可以在不丢失个人文件的情况下做到这一点，但在继续之前创建数据备份仍然是个好主意。(create a backup of your data)

如果您在Windows(Windows)中启动出厂重置时遇到问题，您可以选择在启动时启动到 Windows 恢复环境(booting into the Windows Recovery Environment)后执行此操作。
10.安装任务管理器替代品(Task Manager Alternative)
如果您不想将Windows重置为出厂默认设置，您始终可以使用任务管理器(Task Manager) 替代品，例如 Process Monitor 和 Process Explorer(alternatives such as Process Monitor and Process Explorer)。这些第三方程序同样好，甚至更好。
但是，无法打开任务管理器(Task Manager)可能表明存在更大的问题（例如可能使您的数据面临风险的严重恶意软件感染），因此您可能仍希望尽快重置或重新安装 Windows(reinstall Windows)。
Windows Task Manager Won’t Open? 10 Fixes to Try
If you notice anything unusual with your PC, the first thing you probably do is open the Windows Task Manager. You can then quickly shut down CPU-intensive apps or stuck processes and get things working correctly again. But what if you can’t get to it?
If you attempt to open the Task Manager, but it doesn’t show up, crashes, or you see a “Task Manager not responding” or “Task Manager has been disabled by the Administrator” message, you’ve got a potentially severe problem that needs fixing. We will show you how to do that in Windows 10 and 11.
Try Other Ways to Open Task Manager
You’ve got multiple ways to open the Task Manager in Windows. Suppose you have trouble getting it to show up via the Power User menu or taskbar. In that case, you may want to open it via the Ctrl + Alt + Delete screen (press Ctrl + Alt + Delete and select Task Manager) or use the dedicated Task Manager shortcut (press Ctrl + Shift + Esc) instead. If the problem persists, it’s time to start troubleshooting.
Tip: Have you tried restarting your computer? It sounds like a simple thing to do, but it does help resolve unexpected issues with Windows. Open the Start menu and select Power > Restart to perform a system reboot.
1. Scan for Malicious Activity
Given the Task Manager’s importance to the user, computer viruses often attack and disable it to stop you from interacting with it. So, it’s best to kick things off by scanning your computer for malware.
We recommend that you use Malwarebytes. It’s incredibly effective at malware removal, and the free version is more than enough for the task at hand.
1. Download, install, and open Malwarebytes.
2. Select Scanner.
3. Select Advanced scanners.
4. Select Configure scan.
5. Select the primary partition on your computer—C. Then, leave the rest of the default selections in place and select Scan.
Sometimes, malware infections can be widespread and prevent you from installing or using an antivirus utility. In that case, check out our guide to removing stubborn malware from your PC.
2. Check the Registry Editor
If you see a “Task Manager has been disabled by the Administrator” error despite scanning your computer for malware, run through the Registry Editor-related fix below.
1. Press Windows + R to open the Run box.
2. Type regedit and press Enter.
3. Copy and paste the following path into the top of the Windows Registry Editor window and press Enter:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
4. Select the System folder on the left navigation pane.
5. Double-click the registry entry labeled DisableTaskmgr.
5. Enter a value of 0 and select OK.
If you don’t see the registry entry in step 5, try creating it yourself. Right-click a vacant area on the right side of the Registry Editor window and select New > DWORD (32-BIT) Value. Then, name it as DisableTaskMgr, and set it up with a value of 0.
3. Check Group Policy Editor
If the issue with the Task Manager persists, you must check the Group Policy Editor on your computer and reconfigure a specific policy. Skip this fix if you use the Home edition of Windows 10 or 11.
1. Open the Run box.
2. Type gpedit.msc and press Enter.
2. Navigate to the following location on the left sidebar:
User Configuration > Administrative Templates > System > Ctrl+Alt+Del Options
3. Right-click the Remove Task Manager policy and select Edit.
4. Select Not configured or Disabled.
5. Select Apply > OK to save your changes.
4. Re-Enable Task Manager
Re-Enable is a third-party applet that can quickly re-activate system-related apps after a malware attack. Here’s how to use it.
1. Download, install, and open Re-Enable.
2. Select the radio button next to Task Manager and select Re-Enable.
3. Select Yes to reboot your computer.
5. Run System File Checker and DISM Tool
Next up, run the System File Checker (SFC) and the DISM (Deployment Image Servicing and Management) tool to fix stability issues with the operating system. To do that:
1. Right-click the Start button and select Windows PowerShell (Admin) or Windows Terminal (Admin).
2. Select Yes on the User Account Control (UAC) pop-up.
3. Type the following command and press Enter:
sfc /scannow
4. Wait until the System File Checker scans for and resolves any integrity violations in Windows.
5. Follow that by running the DISM tool:
DISM.exe /Online /Cleanup-image /Restorehealth
Alternatively, you can run both command-line tools via the Command Prompt console. Type cmd into the Start menu and select Run as administrator to open it.
6. Create New Windows Account
A corrupt Windows user profile can also create issues with various system-related apps and services. Create a new account on your computer, sign into it, and check if the Task Manager opens as usual.
1. Open the Start menu and select Settings.
2. Select Accounts.
3. Select Family & other users.
4. Under Other users, select Add account.
5. Select I don’t have this person’s sign-in information.
6. Select Add a user without a Microsoft account.
7. Insert a username and create a local account.
8. Open the Start menu, select your profile portrait, and sign into the new account.
9. Try opening the Task Manager. If you can, here’s what you can then do to migrate your data into the new user account.
7. Update the Operating System
Updating Windows is another fix that can help, especially if the Task Manager freezes at launch or you run into the “Task Manager not responding” error message.
1. Open the Settings app.
2. Select Windows Update.
3. Select Check for updates > Download & install.
You can also uninstall any recent Windows updates if your problems with the Task Manager occurred right after installing them.
8. Restore Windows
If none of the fixes above help, you can choose to restore Windows to an earlier state. However, that’s only possible if you already have System Restore set up.
1. Open the Start menu, type System Protection into the Search box, and press Enter.
2. Under the System Protection tab, select System Restore.
3. Select Next.
4. Pick a restore point from a time when you didn’t have issues opening the Task Manager.
5. Select Finish.
9. Factory-Reset Windows
If System Restore is not active on your computer, consider resetting Windows to factory defaults. Although it’s possible to do that without losing personal files, it’s still a good idea to create a backup of your data before proceeding.
1. Open the Settings app on your PC.
2. Select Update & Security.
3. Select Recovery.
4. Select Reset this PC.
5. Select Keep my files.
If you have trouble initiating a factory reset from within Windows, you can choose to do that after booting into the Windows Recovery Environment at startup.
10. Install a Task Manager Alternative
If you don’t want to reset Windows to factory defaults, you can always use Task Manager alternatives such as Process Monitor and Process Explorer. These third-party programs are just as good, if not better.
However, not being able to open the Task Manager can indicate a much larger problem (such as a serious malware infestation that could put your data at risk), so you may still want to reset or reinstall Windows as soon as possible.
