Steam 的Windows 10客户端应用程序依赖名为Steam 客户端服务(Steam Client Service)的后台服务来有效运行。它处理从安装视频游戏、更新下载内容到激活受支持游戏的反作弊检测功能等关键任务。
但是，假设您在尝试打开Steam时不断遇到“ Steam服务错误” 。在这种情况下，您可能会遇到权限不足、服务配置错误或Steam安装损坏的问题。
通过以下修复列表工作，您应该能够修复 Windows 10 PC 上的“Steam 服务错误”。
重新安装 Steam 服务
“Steam 服务错误”消息包含一个安装服务(Install Service)选项，您可以使用该选项重新安装Steam 客户端服务(Steam Client Service)。如果您还没有，只需选择它，看看是否有帮助。
但是，如果下次启动Steam时（可能在重新启动 PC 后）再次出现相同的错误，请继续进行其余的修复。
以管理员身份运行 Steam
“ Steam服务错误”主要是Steam权限不足造成的。要排除这种情况，您必须以管理权限运行 Steam(run Steam with administrative privileges)。
如果您的桌面上有Steam图标，只需右键单击它并选择Run as administrator。如果您使用开始(Start)菜单打开应用程序，找到并右键单击Steam，指向更多(More)，然后选择以管理员身份运行(Run as administrator)。
如果您以管理员身份运行 Steam 时没有再次出现“ Steam服务错误”，以下是始终以管理员身份运行Steam的方法：(Steam)
1. 打开文件资源管理器并转到此 PC(This PC) >本地磁盘 (C:)(Local Disk (C:)) >程序文件 (86)(Program Files (86)) > Steam。
2. 找到并右键单击标有 steam.exe(steam.exe)的文件。然后，选择属性(Properties)。
3. 切换到兼容性(Compatibility )选项卡。
4. 在设置部分下，选中(Settings )以管理员(Run this program as an administrator)身份运行此程序旁边的框。
5. 选择应用(Apply )>确定(OK)。
重新配置 Steam 客户端服务
默认情况下，Steam客户端应用程序仅在需要时调用Steam 客户端服务(Steam Client Service)。如果无法启动并运行服务，您最终会出现“ Steam服务错误”。您可以通过将Steam 客户端服务(Steam Client Service)配置为与操作系统一起自动启动来解决此问题。
1. 按Windows + R打开运行框。然后，键入services.msc并选择OK。
2. 找到标有Steam 客户端服务的服务(Steam Client Service)。然后，双击它打开Steam 客户端服务属性(Steam Client Service Properties)对话框。
3. 在常规(General )选项卡下，将启动类型(Startup type )设置为自动(Automatic)。
4. 选择应用(Apply)，然后选择确定(OK)。
5. 重新启动计算机并尝试重新打开Steam。
修复 Steam 客户端服务
如果“Steam 服务错误”继续出现在您的计算机上，您必须修复Steam 客户端服务(Steam Client Service)。这是一个相对简单的过程，涉及通过命令提示符(Command Prompt)控制台执行命令。
1. 按Windows + S打开Windows 搜索(Windows Search)。然后，键入cmd并选择以管理员身份运行(Run as administrator)以打开具有管理权限的命令提示符(Command Prompt)控制台。
2. 复制并粘贴以下命令：
“C:\Program Files (x86)\Steam\bin\SteamService.exe” /repair
3. 按回车(Enter)。
将 Steam 添加到 Windows 防火墙
如果Steam(Steam)缺少正确连接互联网所需的权限，“ Steam客户端服务”也可能会出现。因此(Hence)，最好检查Windows 防火墙(Windows Firewall)以确保一切设置正确。
1. 选择系统托盘上的Windows 安全(Windows Security )图标。
2. 转到防火墙和网络保护(Firewall & network protection )>允许应用程序通过防火墙(Allow an app through firewall)。
3. 选择更改设置(Change settings)。
4. 激活Steam(Steam )和Steam Web Helper旁边的两个框。
如果您在Windows 防火墙(Windows Firewall)中没有看到Steam或Steam Web Helper，请选择允许其他应用程序(Allow another app)并在以下目录中添加以下文件：
- Steam： C：程序文件（x86）SteamSteam.exe
- Steam 网络助手：(Steam Web Helper:) C:Program Files (x86)Steam incefcef.win7x64steamwebhelper.exe
5. 选择确定(OK)。
如果您使用带有专用防火墙的第三方防病毒解决方案，请打开其配置窗格并确保将Steam添加为例外。
修复损坏的系统文件
Windows 10 附带一个命令行工具（称为系统文件检查器(System File Checker)） ，可帮助您扫描和修复损坏的系统文件。如果“Steam 服务错误”是由操作系统问题引起的，运行它应该有助于解决这个问题。
1. 打开具有管理权限的命令提示符控制台。(Command Prompt)
2. 键入以下命令：
sfc /scannow
3. 按回车(Enter)。
更新 Windows 10
如果您运行的是过时版本的Windows 10（或者如果您继续推迟操作系统更新(defer operating system updates)），Steam 等程序可能无法正常运行。更新操作系统，看看是否有助于解决问题。
1. 打开开始(Start )菜单并转到设置(Settings)>更新和安全(Update & Security)> Windows 更新(Windows Update)。
2. 选择检查更新(Check for updates)。
3. 选择下载并安装(Download and install)以更新 Windows 10。
回滚 Windows 10
如果您之前在 Windows 10 中设置了系统还原(set up System Restore in Windows 10)，请尝试将Windows 10恢复到Steam在您的 PC 上正常工作的时间。
1. 按Windows + R打开运行框。
2.输入sysdm.cpl并选择OK。
3. 切换到系统保护(System Protection)选项卡并选择系统还原(System Restore)。
4. 选择推荐还原(Recommended restore)以撤消对操作系统的最新更改。或者，选择选择不同的还原点(Choose a different restore point)以选择另一个还原点。
5. 选择下一步(Next )并通过系统还原(System Restore)向导来回滚操作系统。
卸载并重新安装 Steam
如果上述修复都没有帮助，您必须卸载并重新安装Steam。这应该有助于修复由Steam安装损坏导致的“ Steam服务错误”。(Steam)您可以选择通过将相关文件夹复制到其他位置来保持游戏数据的完整性。
1. 打开文件资源管理器(File Explorer)并导航到此 PC(This PC) >本地磁盘 (C:)(Local Disk (C:)) >程序文件 (x86)(Program Files (x86)) > Steam。
2. 将标有 steamapps(steamapps )的文件夹（其中包含您的游戏数据）复制并粘贴到您 PC 上的不同位置。
3. 打开开始(Start )菜单并转到设置(Settings )>应用程序(Apps )>应用程序和功能(Apps & features)。
4. 选择Steam >卸载(Uninstall )以从您的计算机中删除 Steam。
5.下载 Steam 安装程序(Download the Steam installer)并运行它以重新安装Steam。之后将steamapps文件夹复制到Steam目录。
您已修复Steam(Fixed)服务错误(Steam Service Error)
大多数情况下，以管理员身份启动Steam客户端或重新配置Steam 客户端服务(Steam Client Service)以自动运行应该可以帮助您解决Windows 10中的“ (Windows 10)Steam服务错误” 。如果没有，尝试上面的一些高级修复肯定会帮助您解决问题。
How To Fix a Steam Service Error
Steam’s Windows 10 clіent аpplication relies on a background service called the Steam Client Service to run effectively. It hаndles critiсal tаsks ranging frоm installіng video games, updating downloaded content, to activating antі-cheat detection capabilities in supported titles.
However, suppose you keep coming across a “Steam Service Error” as you attempt to open Steam. In that case, you’re likely dealing with insufficient permissions, an incorrectly configured service, or a corrupt Steam installation.
Work your way through the list of fixes that follow, and you should be able to fix the “Steam Service Error” on your Windows 10 PC.
Reinstall Steam Service
The “Steam Service Error” message includes an Install Service option that you can use to re-install the Steam Client Service. If you haven’t already, just select it and see if that helps.
But if the same error shows up again the next time you launch Steam (perhaps after rebooting your PC), move on with the rest of the fixes.
Run Steam as Administrator
The “Steam Service Error” is mainly the result of insufficient Steam permissions. To rule that out, you must run Steam with administrative privileges.
If you have a Steam icon on your desktop, simply right-click it and select Run as administrator. If you use the Start menu to open apps, locate and right-click Steam, point to More, and select Run as administrator.
If the “Steam Service Error” doesn’t re-appear when you run it as administrator, here’s how to run Steam as an administrator always:
1. Open File Explorer and go to This PC > Local Disk (C:) > Program Files (86) > Steam.
2. Locate and right-click the file labeled steam.exe. Then, select Properties.
3. Switch to the Compatibility tab.
4. Under the Settings section, check the box next to Run this program as an administrator.
5. Select Apply > OK.
Re-Configure Steam Client Service
By default, the Steam client application only invokes the Steam Client Service as and when needed. If it fails to get the service up and running, you end up with the “Steam Service Error.” You can fix that by configuring the Steam Client Service to launch automatically alongside the operating system.
1. Press Windows + R to open the Run box. Then, type services.msc and select OK.
2. Locate the service labeled Steam Client Service. Then, double-click it to open the Steam Client Service Properties dialog.
3. Under the General tab, set Startup type to Automatic.
4. Select Apply, then OK.
5. Restart your computer and try re-opening Steam.
Repair Steam Client Service
If the “Steam Service Error” continues to show up on your computer, you must repair the Steam Client Service. It’s a relatively simple procedure that involves executing a command via the Command Prompt console.
1. Press Windows + S to open Windows Search. Then, type cmd and select Run as administrator to open a Command Prompt console with administrative privileges.
2. Copy and paste the following command:
“C:\Program Files (x86)\Steam\bin\SteamService.exe” /repair
3. Press Enter.
Add Steam to Windows Firewall
The “Steam Client Service” could also show up if Steam lacks the required permissions to connect to the internet properly. Hence, it’s best to check the Windows Firewall to ensure that everything’s set up correctly.
1. Select the Windows Security icon on the system tray.
2. Go to Firewall & network protection > Allow an app through firewall.
3. Select Change settings.
4. Activate both boxes next to Steam and Steam Web Helper.
If you don’t see Steam or Steam Web Helper within the Windows Firewall, select Allow another app and add the following files within the directories below:
- Steam: C:\Program Files (x86)\Steam\Steam.exe
- Steam Web Helper: C:\Program Files (x86)\Steam\bin\cef\cef.win7x64\steamwebhelper.exe
5. Select OK.
If you use a third-party antivirus solution with a dedicated firewall, open its configuration pane and make sure to add Steam as an exception.
Repair Corrupted System Files
Windows 10 comes with a command-line tool—dubbed the System File Checker—that helps you scan and repair corrupted system files. If the “Steam Service Error” results from issues with the operating system, running it should help fix that.
1. Open a Command Prompt console with administrative privileges.
2. Type the following command:
sfc /scannow
3. Press Enter.
Update Windows 10
If you run an outdated version of Windows 10 (or if you’ve continued to defer operating system updates), programs such as Steam may have trouble running correctly. Update the operating system and see if that helps resolve the issue.
1. Open the Start menu and go to Settings > Update & Security > Windows Update.
2. Select Check for updates.
3. Select Download and install to update Windows 10.
Roll Back Windows 10
Provided that you’ve set up System Restore in Windows 10 previously, try reverting Windows 10 to a time when Steam worked without issues on your PC.
1. Press Windows + R to open the Run box.
2. Type sysdm.cpl and select OK.
3. Switch to the System Protection tab and select System Restore.
4. Select Recommended restore to undo the most recent changes to the operating system. Or, select Choose a different restore point to pick another restore point.
5. Select Next and work your way through the System Restore wizard to roll back the operating system.
Uninstall and Reinstall Steam
If none of the fixes above helped, you must uninstall and reinstall Steam. That should help fix a “Steam Service Error” caused by a broken Steam installation. You can choose to keep your game data intact by copying the relevant folder to a different location.
1. Open File Explorer and navigate to This PC > Local Disk (C:) > Program Files (x86) > Steam.
2. Copy and paste the folder labeled steamapps (which contains your game data) to a different location on your PC.
3. Open the Start menu and go to Settings > Apps > Apps & features.
4. Select Steam > Uninstall to remove Steam from your computer.
5. Download the Steam installer and run it to re-install Steam. Copy the steamapps folder to the Steam directory after that.
You’ve Fixed the Steam Service Error
Most of the time, launching the Steam client as an administrator or re-configuring the Steam Client Service to run automatically should help you resolve the “Steam Service Error” in Windows 10. If not, trying some of the advanced fixes above will surely help you sort things out.
