修复无法在任务管理器中更改进程优先级： ^{(Fix Unable to change process priority in Task Manager: )}如果您尝试在任务管理器中更改进程的优先^{(Task Manager)}级并收到以下错误消息“无法更改优先级^{(Change Priority)}。此操作无法完成。访问^(Access)被拒绝”那么您来对地方了，因为今天我们将讨论如何解决此问题。即使您拥有正确的管理员安全权限并且以管理员身份运行程序，您仍然会面临同样的错误。一些用户在尝试将进程优先级更改为实时或高时也会遇到以下错误：

Unable to set Realtime priority. The priority was set to High instead

用户通常只有在无法正确访问该程序时才需要更改进程优先级，因为他们需要系统提供大量资源。例如，如果您无法访问高图形密集型游戏，或者如果游戏在中间崩溃，那么您可能需要打开任务管理器^{(Task Manager)}并为进程分配实时或高优先级才能玩游戏而不会崩溃或滞后问题。

但是，由于访问被拒绝错误消息，您将无法为任何进程分配高优先级。您能想到的唯一解决方案是启动到安全模式并尝试分配所需的优先级，那么您将能够在安全模式下成功更改优先级，但是当您正常启动到Windows并再次尝试更改优先级时将再次面临相同的错误消息。

修复^(Fix)无法在任务管理器中更改进程优先级^{(Task Manager)}

确保 创建一个还原点^{(create a restore point)} 以防万一出现问题。

方法一：显示所有用户的进程^{(Method 1: Show processes from all users)}

注意：^(Note:)这仅适用于Windows 7、Vista和 XP。

1.确保您使用的是管理员帐户^{(administrator account)}，然后右键单击任务栏^(Taskbar)并选择任务管理器。^{(Task Manager.)}

2.运行您想要更改优先级的程序或应用程序。

3.在任务管理器中勾选“显示所有用户的进程^{(Show processes from all users)}”以确保它以管理员^{(Administrator)}身份运行。

4.再次尝试^(Try)更改优先级，看看您是否能够 修复无法更改任务管理器中的进程优先级问题。^{(Fix Unable to change process priority in Task Manager issue.)}

方法二：给管理员完全权限^{(Method 2: Give full permission to the Administrator)}

1.右键单击任务栏^(Taskbar)，然后选择任务管理器。^{(Task Manager.)}

2.搜索要更改优先级的程序，然后右键单击它并选择属性。^{( Properties.)}

3.切换到安全选项卡^{(Security tab)}并单击编辑。^(Edit.)

4.确保为管理员选中完全控制。^{(Full control)}

5.单击应用，然后单击确定。

6.重新启动您的 PC 并再次尝试更改进程的优先级。

方法 3：打开或关闭 UAC^{(Method 3: Turn ON or OFF UAC)}

1.按 Windows 键 + R 然后输入“ control nusrmgr.cpl ”（不带引号）并按 Enter。

2.在下一个窗口中单击更改用户帐户控制设置。^{(Change User Account Control settings.)}

3.首先，将滑块一直拖到下方^{(drag the slider to all the way to down)}，然后单击“确定”。

4.重新启动您的PC并再次尝试更改程序的优先级，如果您仍然遇到拒绝访问错误^{(access denied error)}，请继续。

5.再次打开用户帐户控制^{(User Account Control)}设置窗口并将滑块一直向上拖动^{(drag the slider all the way to up)}并单击确定。

6.重新启动您的PC，看看您是否能够修复无法更改任务管理器中的进程优先级问题。^{(Fix Unable to change process priority in Task Manager issue.)}

方法四：开机进入安全模式^{(Method 4: Boot into safe mode)}

使用此处列出的任何方法^{(method listed here)}启动到安全模式，然后尝试更改程序的优先级并查看它是否有效。

方法 5：尝试进程资源管理器^{(Method 5: Try Process Explorer)}

从这里下载 Process Explorer^{(Download Process Explorer)}程序，然后确保以管理员^{(Administrator)}身份运行它并更改优先级。

这对于无法将进程优先级更改为实时并面临此错误“无法设置实时优先级”的用户也将有所帮助。相反，优先级设置为高。^{(Unable to set Realtime priority. The priority was set to High instead.)}“

注意：^(Note:)将进程优先级设置为实时是非常危险的，因为关键系统进程以较低的优先级运行，如果它们缺乏CPU资源，那么结果将根本不会令人愉快。所有互联网文章都在误导用户相信将进程优先级更改为实时将使它们运行得更快，这并非都是真的，在极少数情况下或例外情况下这是真的。

方法6：修复安装Windows 10^{(Method 6: Repair Install Windows 10)}

这种方法是最后的手段，因为如果没有任何效果，那么这种方法肯定会修复您 PC 的所有问题。修复^{(Repair Install)}仅使用就地升级来修复系统问题而不删除系统上存在的用户数据进行安装。因此，为了修复无法在^{(Fix Unable)}任务管理器^{(Task Manager)}中更改进程优先级，请按照本文查看如何轻松修复安装 Windows 10。^{(How to Repair Install Windows 10 Easily.)}

Fix Unable to change process priority in Task Manager

Fix Unable to change process priority in Task Manager: If you are trying to change the priority of a process in Task Manager and received the following error message “Unable to Change Priority. This operation could not be completed. Access is denied” then you are at the right place as today we are going to discuss on how to fix this issue.

Users usually need to change the process priority only when they are not able to access that program properly as they demand high resources from the system. For example, if you are not able to access a high graphics intensive game or if the game crashes in the middle then probably you need to open Task Manager and assign real-time or high priority to the processes in order to play the game without crashing or lagging issues.

But again you will not be able to assign high priority to any process because of the access denied error message. The only solution which you can think of is to boot into safe mode and try to assign the desired priority, well you will be able to successfully change the priority in Safe mode but when you normally boot into Windows and again try to change the priority you will again face the same error message.
