启动Windows PC 会激活数十亿行代码，这些代码编译成各种可执行文件(executable files)和支持Windows操作系统的系统进程。其中一些进程比其他进程更重要，从顶部的Windows 系统内核到底部的(Windows system kernel)YourPhone 智能手机控制应用程序(YourPhone smartphone control app)。
然而， Windows 10(Windows 10) PC上鲜为人知的系统进程之一是slui.exe。此过程负责激活Windows 10许可证，包括(Windows 10)检查您的许可证是否为正版(checking if your license is genuine)。如果您想了解有关 slui.exe 的更多信息，以下是您需要了解的内容。
什么是 Slui.exe，它安全吗？(What Is Slui.exe and Is It Safe?)
slui.exe进程(slui.exe)（也称为Windows 激活客户端(Windows Activation Client)）是一个重要的Windows系统进程，它在(Windows)Windows 10许可证的激活中发挥作用。每台Windows 10 PC 都需要一个许可证，该许可证授予用户访问所有 Window 功能的权限。
虽然Windows 10在没有许可证的情况下可以在短时间内运行，但如果没有激活许可证，对功能的访问将开始下降。未能激活Windows 10（或使用正版许可证密钥）最终将导致Windows不再工作，直到您解决问题为止。
这是微软(Microsoft)用来保护其收入的最先进的功能之一。由于Windows许可证需要花钱，任何没有许可证的 PC 都会导致Microsoft的收入损失。这同样适用于任何试图使用激活破解或在线许可证密钥绕过这些许可限制的Windows PC用户。(Windows PC)
这就是 slui.exe 发挥作用的地方。当您尝试更改Windows 10 产品密钥或尝试激活Windows时，将运行此过程。Windows还可以随时自动运行此过程，以检查您的许可证是否真实、有效并且可以使用。
作为一个正版系统进程，slui.exe是完全可以安全运行的。但是，唯一的例外是，如果您尝试使用在线激活工具修补或修改该过程。这些有时可能与恶意软件打包在一起(packaged with malware)，使用它们可能会让您别无选择，只能重置或重新安装 Windows 10(reset or reinstall Windows 10)。
如何从 Windows 10 禁用或删除 Slui.exe(How to Disable or Remove Slui.exe from Windows 10)
如果您正在考虑尝试删除、禁用或以其他方式干扰Windows 10上的 slui.exe 系统进程，我们的建议很简单：不要(don’t)。
参与Windows 10激活和许可的进程（包括 slui.exe）通常受到保护，被认为是必不可少的，不应受到干扰。
这样做可能会导致Windows吊销您的许可并限制您对功能的访问。未激活的Windows PC不是很有用。虽然有在线工具可以帮助绕过正版激活，但不推荐使用(aren’t recommended)这些工具，因为它们违反了Windows使用条款，并且可能损坏您的Windows安装文件。
没有办法绕过它 - slui.exe 和其他涉及Windows许可和激活的进程将继续存在。虽然您可以尝试绕过或禁用它，但这样做会使您的 PC 处于危险之中，并且在任何情况下都不应尝试。
在任务管理器中识别 Slui.exe 进程(Identifying the Slui.exe Process in Task Manager)
如果您看到 slui.exe（或Windows 激活客户端(Windows Activation Client)）在任务管理器(Task Manager)中运行，您可以放心，继续运行是安全的。试图结束进程（或完全删除可执行文件）可能会适得其反，并迫使您将 PC 恢复为出厂设置(restore your PC to factory settings)。
但是，如果您想确保正在运行的进程是真实的，您可以在任务管理器(Task Manager)本身中执行此操作。如果您之前曾尝试使用在线激活工具绕过Windows正版许可系统，您可能希望这样做，但您也可以随时这样做，以使自己安心。
- 为此，您首先需要通过右键单击开始(Start)菜单或任务栏并选择任务管理器来打开一个新的(Task Manager)任务管理器(Task Manager)窗口。
- 在任务管理器(Task Manager)窗口中，在进程(Processes)选项卡中找到Windows 激活(Windows Activation )或Windows 激活客户端。(Windows Activation Client )或者，在详细信息选项卡中找到(Details)slui.exe。右键单击(Right-click)该条目，然后选择打开文件位置以在新的(Open file location)文件资源管理器(File Explorer)窗口中打开包含 slui.exe 的文件夹。
合法的 slui.exe 系统进程位于C:\Windows\System32 文件夹中。如果运行的 slui.exe 进程是正版的，文件资源管理器(File Explorer)将打开此文件夹并选择slui.exe文件。如果没有，或者您仍然不确定，则需要使用Microsoft Defender或其他第三方应用程序安排防病毒扫描。(schedule an antivirus scan)
如何使用 SLUI.exe 激活或更改 Windows 10 许可证(How to Use SLUI.exe to Activate or Change a Windows 10 License)
作为Windows PC(Windows PCs)许可系统的一部分，您可以使用SLUI.exe进程来激活您的Windows 10许可证或更改您当前的许可证密钥。您可以使用Run(Run)手动运行该进程，但在Windows 10 设置(Settings)菜单中选择更改您的许可证也将启动 slui.exe 进程。
使用 Run 手动启动 Slui.exe(Launching Slui.exe Manually Using Run)
- 要手动运行SLUI.exe，请右键单击“开始(Start)”菜单并选择“运行”(Run)选项。或者，按键盘上的Windows + R 键。
- 在“运行”对话框中，键入slui（或slui.exe）并选择“确定(OK)”运行它。这将在Windows 设置(Windows Settings)中打开相关菜单。如果您在在线激活Windows时遇到问题并需要电话支持来帮助您激活它，请改为键入slui 4。
- 您接下来看到的内容将取决于您的 PC 是否具有当前许可证。如果您的 PC 缺少当前许可证，则需要在此处提供一个。如果它有许可证，您可以通过在提供的框中输入新的许可证密钥来替换它，然后选择下一步(Next)并按照屏幕上的其他说明进行操作。
使用 Windows 设置启动 Slui.exe(Launching Slui.exe Using Windows Settings)
- 要使用Windows 设置(Windows Settings)启动 slui.exe 进程并访问各种选项以激活或更改您的许可证，请右键单击开始(Start)菜单并选择设置(Settings)。
- 在设置(Settings)菜单中，选择更新和安全(Update & Security )>激活(Activation)。激活(Activation)菜单的外观会发生变化，具体取决于您是否安装并激活了正版许可证。例如，要更改您的密钥（并运行 slui.exe 进程），请选择更改产品密钥(Change product key)选项。
- 在“输入产品密钥(Enter a product key)”框中，键入新的Windows 10许可证密钥并选择“下一步”(Next)继续，然后按照屏幕上的任何其他说明完成该过程。
使用许可的 Windows 10 电脑(Using a Licensed Windows 10 PC)
正如本指南所述，slui.exe 进程是Windows 10中的重要组件。作为负责系统许可的进程之一，slui.exe 是最受保护的进程之一。slui.exe 极不可能存在安全风险，但如果您使用过在线激活工具，您可能需要扫描您的 PC 以查找恶意软件(scan your PC for malware)。
您还可以将您的 Windows 产品密钥链接到您的帐户，这样您就可以在重置或(link your Windows product key to your account)升级 PC(upgrade your PC)时转移您的密钥。但是，如果这不起作用，您始终可以使用 slui.exe 和原始产品密钥(original product key)传输您的 Windows 10 许可证(transfer your Windows 10 license)。但是，您可能需要检查该密钥是否支持您的Windows版本。
What is slui.exe in Windows and Is It Safe?
Booting up a Windows РC activates the billions of lines of code compiled into various executable files and system processes that underpin the Windows operating system. Some of these processes are more important than others, from the Windows system kernel at the top to the YourPhone smartphone control app at the bottom.
One of the lesser known system processes on a Windows 10 PC, however, is slui.exe. This process is responsible for Windows 10 license activation, including checking if your license is genuine. If you want to know more about slui.exe, here’s what you need to know.
What Is Slui.exe and Is It Safe?
The slui.exe process (also known as the Windows Activation Client) is an important Windows system process that plays a part in the activation of Windows 10 licenses. Each Windows 10 PC requires a license that grants the user access to all of Window’s features.
While Windows 10 will work without a license for a short period of time, access to features will begin to degrade if a license isn’t activated. Failure to activate Windows 10 (or use a genuine license key) will eventually result in Windows no longer working until you resolve the situation.
This is one of the most advanced features that Microsoft uses to protect its revenue. Since a Windows license costs money, any PC without a license results in lost earnings for Microsoft. The same applies to any Windows PC user that tries to bypass these licensing restrictions using activation cracks or online license keys.
That’s where slui.exe comes in. This process will run when you try to change your Windows 10 product key or if you attempt to activate Windows. Windows may also run this process automatically at any point to check that your license is genuine, active, and ready to use.
As a genuine system process, slui.exe is completely safe to run. The only exception to this, however, is if you’ve tried to patch or modify the process using online activation tools. These can sometimes be packaged with malware, and using them may leave you with no option but to reset or reinstall Windows 10.
How to Disable or Remove Slui.exe from Windows 10
If you’re thinking about trying to remove, disable, or otherwise interfere with the slui.exe system process on Windows 10, our advice is simple: don’t.
Processes involved in the activation and licensing of Windows 10 (including slui.exe) are generally protected, considered essential, and shouldn’t be interfered with.
Doing so could cause Windows to revoke your licensing and restrict your access to features. A non-activated Windows PC isn’t very useful. While there are online tools to help bypass genuine activation, these aren’t recommended as they breach the Windows terms of use and can damage your Windows installation files.
There’s no way around it—slui.exe and other processes involved in Windows licensing and activation are here to stay. While you can try to bypass or disable it, doing so puts your PC at risk and shouldn’t be attempted under any circumstances.
Identifying the Slui.exe Process in Task Manager
If you see slui.exe (or the Windows Activation Client) running in Task Manager, you can rest assured that it’s safe to leave running. Trying to end the process (or remove the executable file entirely) is likely to backfire and force you to restore your PC to factory settings.
If you want to make sure that the running process is genuine, however, you can do so from within Task Manager itself. You may wish to do this if you’ve previously tried to circumvent the Windows genuine licensing system using online activation tools, but you can also do it for your own peace of mind at any point.
- To do this, you’ll need to first open a new Task Manager window by right-clicking the Start menu or the taskbar and selecting Task Manager.
- In the Task Manager window, locate Windows Activation or Windows Activation Client in the Processes tab. Alternatively, locate slui.exe in the Details tab. Right-click the entry, then select Open file location to open the folder containing slui.exe in a new File Explorer window.
The legitimate slui.exe system process is found in the C:\Windows\System32 folder. If the running slui.exe process is genuine, File Explorer will open this folder and select the slui.exe file. If it doesn’t, or you’re still unsure, you’ll need to schedule an antivirus scan using Microsoft Defender or another third-party app.
How to Use SLUI.exe to Activate or Change a Windows 10 License
As part of the licensing system for Windows PCs, you can use the SLUI.exe process to activate your Windows 10 license or change your current license key. You can run the process manually using Run, but selecting to change your license in the Windows 10 Settings menu will also launch the slui.exe process.
Launching Slui.exe Manually Using Run
- To run SLUI.exe manually, right-click the Start menu and select the Run option. Alternatively, press the Windows + R keys on your keyboard.
- In the Run dialog box, type slui (or slui.exe) and select OK to run it. This will open the relevant menu in Windows Settings. If you’re having trouble activating Windows online and require telephone support to help you activate it, type slui 4 instead.
- What you see next will depend on if your PC has a current license or not. If your PC lacks a current license, you’ll need to provide one here. If it has a license, you’ll be able to replace it by typing in a new license key in the box provided, then selecting Next and following the additional on-screen instructions.
Launching Slui.exe Using Windows Settings
- To launch the slui.exe process using Windows Settings and access the various options to activate or change your license, right-click the Start menu and select Settings.
- In the Settings menu, select Update & Security > Activation. The Activation menu will change in appearance, depending on whether you have a genuine license installed and activated or not. For instance, to change your key (and run the slui.exe process), select the Change product key option.
- In the Enter a product key box, type a new Windows 10 license key and select Next to continue, then follow any additional on-screen instructions to complete the process.
Using a Licensed Windows 10 PC
As this guide explains, the slui.exe process is a vital component in Windows 10. As one of the processes responsible for system licensing, slui.exe is one of the most protected. It is extremely unlikely that slui.exe is a security risk, but if you’ve used online activation tools, you may want to scan your PC for malware.
You can also link your Windows product key to your account, allowing you to transfer your key when you reset or upgrade your PC. If that doesn’t work, however, you can always transfer your Windows 10 license using slui.exe and the original product key. You may need to check that the key supports your version of Windows, however.
