Steam 是网络上最受欢迎的游戏和社区平台(Steam is the most popular gaming and community platform)。多年来，它以其令人难以置信的销量、几乎每款游戏的大量成就以及易于使用的好友系统而闻名。
它是大多数 PC 游戏玩家的指挥中心。当它出现故障或拒绝打开时，它会影响您的整个游戏体验。如果Steam没有打开，您可以通过以下几种方法来修复它，从最简单的方法到最激烈的方法。
检查 Steam 是否已关闭
在尝试任何其他修复之前，您应该尝试的第一件事是确定 Steam 是否已关闭。如果服务关闭，其他任何事情都不会起作用。您可以查看网站Is Steam Down? 进行验证，如果Steam(Steam)不工作，该网站还建议其他潜在的娱乐渠道。
您也可以尝试Down Detector，它不仅会显示他们的服务是否可以访问Steam，还会显示其他用户是否遇到类似问题。
以管理员身份运行 Steam
当您以管理员身份运行程序(run a program as the administrator)时，您是在告诉系统它是安全的，无论是否违反安全规定，都应该启动它。如果有任何后台程序或防火墙阻止程序启动，以管理员身份运行它们应该允许程序打开。
在开始(Start)菜单中选择Steam图标并右键单击它，然后选择以管理员身份运行。(Run as administrator.)这将绕过任何试图阻止 Steam 启动的程序。这是一种可能并不总是有效的简单方法，但它是您应该首先尝试的方法之一。
更新视窗
Steam 执行各种安全检查，以确保程序中没有恶意软件运行。桌面客户端还使用Chromium(Chromium)浏览器的内置版本，如果它未在最新版本的Windows上运行，有时会引发错误。
确保(Make)您的操作系统完全是最新的。如果有可用的更新，请继续安装它们。同样，这不是一个有保证的修复，但会消除一个潜在的问题来源。
通过任务管理器结束 Steam
程序(Programs)和服务通常会遇到错误，它们被您的计算机标记为可运行，但实际上不会启动。在这种情况下，请确保任务管理器(Task Manager)中没有运行相同的任务并关闭任何相同的任务。对于 Steam，有两个过程需要寻找。
首先是Steam 客户端 Boostrapper(Steam Client Boostrapper)，这是Steam本身的实际进程。结束此应用程序将关闭Steam。另一个是Steam 客户端 Webhelper(Steam Client Webhelper)，这是一个后台进程，有时会在用户尝试启动Steam时引发问题。
(Shut)在尝试再次打开Steam之前，请(Steam)关闭这两个程序和任何相关程序（在后台与Steam相关的任何进程） 。
清除 Steam 应用缓存
您的计算机将您经常使用的应用程序存储在缓存(apps you frequently use in a cache)中，以便这些程序在您下次使用时能够更快、更轻松地启动。大多数情况下，这很顺利——但有时缓存会存储错误的数据并导致错误。如果您的Steam缓存包含错误，Steam可能无法打开。
打开文件资源管理器(File Explorer)并导航到本地磁盘 (C:)(Local Disk (C:)) >程序文件 (x86( Program Files (x86) ) > Steam > appcache。复制整个 appcache 文件夹并将其粘贴到其他位置以备不时之需。
完成此操作后，删除appcache文件夹并尝试启动Steam。当您这样做时，将创建一个新文件夹，希望没有任何阻止Steam首次打开的错误。
卸载并重新安装 Steam
当所有其他方法都失败时，将其关闭并重新打开 - 从头开始。从您的计算机上完全卸载Steam 。转到Settings > Apps > Apps and features，然后向下滚动，直到找到 Steam。单击该图标，然后单击卸载(Uninstall)按钮以从您的 PC中删除Steam 。
完成后，前往Steam主网站。在屏幕顶部，单击安装 Steam(Install Steam)图标。或者，只需点击此链接(this link)。下载最新版本的Steam，重新安装，然后再次尝试启动。这样做会从您的计算机中清除大部分存储的数据，并消除大多数安装问题。
请记住(Bear)，卸载Steam还会删除您的所有游戏以及未备份到云端的所有保存数据。
执行系统还原
如果所有其他方法都失败并且Steam仍未打开，您可以在知道Steam正常工作时尝试将系统还原到上一个点。(System Restore)各种事情都可能导致其他似乎无法解决的问题，尤其是Windows 更新(Windows Updates)。发生这种情况时，您可以执行系统还原(System Restore)以恢复到系统的先前版本。
Windows 10 使查找系统还原(System Restore)功能变得比必要更困难。有两种主要的访问方式。首先(First)，打开控制面板(Control Panel)>系统和安全。( System and Security. )您将看到两个下拉菜单： Security 和Maintenance。在这两个之下是一个称为恢复的选项。(Recovery.)
选择恢复(Recovery )，然后选择打开系统还原(Open System Restore)。这样做将打开系统还原向导(System Restore Wizard)。按照屏幕上的说明继续。选择Next后，您可以从在系统更新和其他事件之前创建的一系列“还原点”中进行选择。您也可以手动创建还原点。
Steam已经存在了很长时间，在其存在期间出现了各种可能导致Steam无法打开的错误。虽然大多数都很快得到解决，但也有一些问题挥之不去——但好消息是这些步骤将帮助您解决您在使用Steam(Steam)时遇到的几乎所有问题。
解决问题，打开您的图书馆，然后重新开始游戏。
Steam Not Opening? 7 Ways to Fix
Steam is the most popular gaming and community platform on the web. It has built a reputation over the years for its incredible sales, massive number of achievements for almost every game, and easy-to-use friend system.
It’s the command center for most PC gamers. When it goes down or refuses to open, it impacts your entire gaming experience. If Steam is not opening, here are several ways you can fix it ordered from the easiest method to the most drastic.
Check if Steam Is Down
The first thing you should try before attempting any other fix is to find out if Steam is down. If the service is down, nothing else will work. You can check the website Is Steam Down? to verify, and the website also suggests other potential outlets for entertainment if Steam isn’t working.
You can also try Down Detector, which will not only show whether their service can access Steam but also if other users are experiencing similar problems.
Run Steam as Administrator
When you run a program as the administrator, you are telling the system that it’s safe and should be started regardless of security violations. If there are any background programs or firewalls blocking a program from starting, running them as the administrator should allow a program to open anyway.
Choose the Steam icon in your Start menu and right-click it, then select Run as administrator. This will circumvent any programs trying to stop Steam from booting. It’s a simple method that might not always work, but is one of the first things you should try.
Update Windows
Steam performs a variety of security checks to ensure there’s no malware running within the program. The desktop client also uses a built-in version of the Chromium browser, which can sometimes throw an error if it isn’t running on the latest version of Windows.
Make sure your operating system is completely up to date. If there are updates available, go ahead and install them. Again, this is not a guaranteed fix, but will eliminate one potential source of problems.
End Steam Through the Task Manager
Programs and services will often encounter an error where they’re marked as operational by your computer, but will not actually boot. In situations like this, ensure there are no identical tasks running in the Task Manager and shut down any that are. For Steam, there are two processes to look for.
The first is Steam Client Boostrapper, which is the actual process of Steam itself. Ending this application will shut down Steam. The other is the Steam Client Webhelper, a background process that has sometimes caused problems when users tried to boot Steam.
Shut down both of these and any related programs (anything process that is related to Steam in the background) before attempting to open Steam again.
Clear the Steam App Cache
Your computer stores apps you frequently use in a cache that allows those programs to boot more quickly and easily the next time you use them. Most of the time, this works without a hitch–but there are times when the cache stores the wrong data and results in errors. If your Steam cache contains an error, Steam might not open.
Open File Explorer and navigate to Local Disk (C:) > Program Files (x86) > Steam > appcache. Copy the entire appcache folder and paste it somewhere else in case you need it as a backup.
After you have done this, delete the appcache folder and try to launch Steam. A new folder will be created when you do, hopefully free of any errors that prevented Steam from opening the first time around.
Uninstall and Reinstall Steam
When all else fails, turn it off and turn it back on–from the ground up. Fully uninstall Steam from your computer. Go to Settings > Apps > Apps and features and then scroll down until you find Steam. Click the icon and then click the Uninstall button to remove Steam from your PC.
Once this has finished, go to the main Steam website. At the top of the screen, click the Install Steam icon. Alternatively, just follow this link. Download the latest version of Steam, reinstall it, and try to boot it again. Doing this clears the majority of the stored data from your computer and eliminates the majority of installation problems.
Bear in mind that uninstalling Steam will also remove all of your games and any save data that isn’t backed up to the cloud.
Perform a System Restore
If all else fails and Steam is still not opening, you can try a System Restore to a previous point when you know Steam worked. Various things can cause problems that nothing else seems to fix, especially Windows Updates. When this happens, you can perform a System Restore to revert back to a previous version of your system.
Windows 10 makes it a bit more difficult than necessary to find the System Restore function. There are two main ways to access it. First, open Control Panel > System and Security. You’ll see two drop-down menus: Security and Maintenance. Beneath these two is an option called Recovery.
Select Recovery and then select Open System Restore. Doing this will open the System Restore Wizard. Follow the on-screen instructions to proceed. Once you select Next, you can choose from a series of “restore points,” created before system updates and other events. You can also manually create restore points.
Steam has been around for a long time, and during its existence there have been various bugs that crop up that can lead to Steam not opening. While most get resolved quickly, there are a few that linger–but the good news is these steps will help you resolve nearly any issue you encounter with Steam.
Fix the problem, open your library, and get back to gaming.
