Google会频繁发布更新以增强其旗舰Chrome浏览器的性能、稳定性和安全性。主要版本升级还通过新功能和隐藏的实验标志(hidden experimental flags)改善了浏览体验。
Chrome会在发布后的几天内自行更新到最新版本，以确保您不会错过任何内容。但您也可以手动启动更新以加快速度。
但是，如果Windows版本的Chrome无法自行更新、在手动更新期间挂起或抛出错误代码，可能有以下几个原因：
- 网络相关问题
- 兼容性问题
- 错误配置的Google 更新服务(Google Update Service)
- 恶意扩展和浏览器劫持者
- 文件损坏或丢失
在大多数情况下，您可以通过访问关于 Chrome(About Chrome)屏幕（打开更多(More )菜单并选择帮助(Help )>关于 Google Chrome ）来确定(About Google Chrome)Chrome更新失败背后的问题。例如，带有代码3、11、7和12的错误消息表明网络连接的复杂性。
下面的解决方案可以解决Windows版 Google Chrome(Google Chrome)中大部分更新相关的问题。最好在完成每个修复程序时退出并重新启动浏览器。
退出 Chrome 并重新启动计算机
仅重新启动您的 PC 就可以解决许多随机弹出并阻止Chrome更新的小错误和故障。所以现在就这样做并尝试另一个Chrome更新，然后再进行其余的修复。
运行内置网络疑难解答(Built-In Network Troubleshooters)
假设一个失败的Chrome更新点位于有故障的互联网连接或接入点。在这种情况下，在Windows(Windows)中运行内置的网络相关疑难解答可能会帮助您在Chrome未更新时进行诊断和修复。
1. 打开开始(Start )菜单并选择设置(Settings)。
2. 选择更新和安全(Update & Security)。
3. 切换到故障排除(Troubleshoot )选项卡。
4，选择其他疑难解答(Additional Troubleshooters)。
5. 运行Internet 连接(Internet Connections)疑难解答。
6. 执行建议的建议来修复故障排除程序检测到的问题。
7. 向下滚动附加疑难解答(Additional troubleshooters)屏幕并运行传入连接(Incoming Connections)和网络适配器(Network Adapters)疑难解答。
刷新 DNS 缓存
过时的域名系统 (DNS) 缓存(Domain Name System (DNS) cache)会阻止Chrome连接到 Google 的更新服务器。清除它应该有助于解决这个问题。
1. 按Windows + X打开高级用户菜单(Power User Menu)。然后，选择Windows PowerShell (Admin)。
2. 键入以下命令并按Enter：
ipconfig /flushdns
3. 退出 Windows PowerShell。
续订计算机的 IP 租约
如果您在整个Chrome中遇到不稳定的互联网连接，请尝试为您的 PC重置 IP（互联网协议）租约(resetting the IP (Internet Protocol) lease)。
1. 按Windows + X并选择Windows PowerShell (Admin)。
2.依次执行以下命令：
ipconfig /release
ipconfig /renew
3. 退出 Windows PowerShell。
重置路由器和网络设置
如果Chrome在连接到 Google 更新服务器或从 Google 更新服务器下载时继续遇到问题，请尝试重置路由器(resetting the router)。如果失败，您必须在 Windows 中重置网络设置(reset the network settings in Windows)。
禁用或重新配置兼容模式(Compatibility Mode)
如果您已将Chrome配置为在(Chrome)Windows XP或Windows Vista的兼容模式下运行，则无法更新浏览器，因为Google不再支持这两种操作系统。停用兼容模式（或选择 Windows 7 或更高版本）可以帮助解决此问题。
1. 右键单击 Google Chrome桌面快捷方式并选择属性(Properties)。
假设(Suppose)您不使用桌面快捷方式，打开文件资源管理器(File Explorer)并转到Local Disk (C:) > Program Files > Google > Chrome > Application。然后，右键单击chrome.exe并选择Properties。
2.切换到兼容性(Compatibility)选项卡并取消选中以兼容模式运行此程序(Run this program in compatibility mode for)选项。或者，选择Windows 7或更新版本的 Windows。
3. 选择应用(Apply)>确定(OK)以保存更改。
停用 Chrome 扩展程序
扩展程序有助于增强Chrome中的功能，但它们也可能产生冲突并阻止浏览器更新。在尝试其他更新之前尝试禁用它们。
为此，请打开Extensions菜单（位于屏幕右上角）并选择Manage extensions。然后，关闭每个活动分机旁边的开关。
检查有害软件
失败的Chrome更新也可能源于恶意扩展、浏览器劫持者和其他形式的有害软件。
为了帮助您解决这个问题，Chrome自带了一个内置于浏览器本身的恶意软件扫描程序。打开Chrome的更多(More)菜单，然后转到设置(Settings)>重置( Reset) 和清理(and clean up)>清理计算机(Clean up computer)以运行它。
如果Chrome设法检测并删除有害软件，请使用 Windows 安全(using Windows Security)中心或知名的第三方恶意软件删除实用程序(reputed third-party malware removal utility)运行系统范围的恶意软件扫描。
查看防火墙设置
如果您使用带有集成防火墙的第三方反恶意软件实用程序，请打开其配置窗格并确保Google Chrome和Google 安装程序(Google Installer)( GoogleUpdate.exe ) 有权连接到 Internet。
您还必须确保您没有限制访问以下网站：
- 工具.google.com (tools.google.com )
- dl.google.com
或者，在更新期间禁用计算机上运行的任何第三方反恶意软件实用程序也可能会有所帮助。
如果您仅使用 Windows 安全中心，请查看 Windows 防火墙的规则和设置(look around the Windows Firewall’s rules and settings)以确认没有任何问题。
重新配置Google 更新服务(Google Update Service)
Chrome依靠称为Google 更新服务(Google Update Service)的后台服务来自动应用更新。如果它始终无法做到这一点（例如，您只能手动更新浏览器），则必须将服务配置为与操作系统一起启动。
1. 按Windows + R打开运行框。然后，输入services.msc并选择OK以打开 Services 小程序。
2. 找到并双击标有Google 更新服务 (gupdate)(Google Update Service (gupdate))的条目。
3. 将启动类型(Startup type )设置为自动(Automatic)。
4. 选择应用(Apply )>确定(OK )以保存更改。
5. 找到并双击Google 更新服务 (gupdatem)(Google Update Service (gupdatem))并重复步骤3 – 4。
6. 重新启动您的计算机。
重置谷歌浏览器
如果上述修复未能解决Chrome未更新，您必须重置Chrome。这应该可以解决阻止浏览器更新的任何损坏或冲突配置。您不会丢失书签、历史记录或密码等个人数据，但我们建议您将数据同步到 Google 帐户(syncing your data to a Google Account)（如果您还没有）作为预防措施。
要重置 Chrome，请打开 Chrome 的“设置”(Settings )窗格，然后转到“高级(Advanced )” > “重置和清理”(Reset and clean up ) > “将所有设置重置为默认值”(Reset all settings to defaults)。然后，选择重置设置(Reset settings )确认。
重新安装谷歌浏览器
如果重置Chrome没有帮助，您必须从头开始重新安装它。这不仅会安装最新版本的浏览器，而且该过程还应该处理阻止Chrome继续更新的任何损坏或丢失的文件。
由于您会丢失所有数据，因此您必须将书签、密码和设置同步到Google 帐户(Google Account)。然后，转到开始(Start)>设置(Settings)>应用程序和功能(Apps and Features)并选择Google Chrome >卸载(Uninstall)。
然后从以下目录中的(Follow)Chrome安装中删除所有剩余的文件夹：
- 本地磁盘 (C:)(Local Disk (C:)) >程序文件(Program Files)> Google > Chrome
完成后，下载 Chrome 安装程序存根(download the Chrome installer stub)或独立安装程序(standalone installer)并启动它以重新安装Google Chrome。
更新操作系统
更新Windows本身有助于修复阻止(Windows)Chrome正常工作或更新的已知系统相关错误。如果您有一段时间没有这样做，请立即尝试应用最新的操作系统更新。
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)以更新操作系统。
Chrome 完全最新
使Chrome(Chrome)保持最新状态可确保您始终获得最佳版本的浏览器，因此花时间修复任何与更新相关的问题是非常值得的。但是，这并不能阻止浏览器成为资源消耗者。
因此，如果您愿意尝试新的东西（或者如果Chrome继续无法更新），请检查这些轻量级 Chromium 浏览器替代品(lightweight Chromium browser alternatives)。
Chrome Not Updating on Windows? 13 Ways to Fix
Google publishes frequent uрdatеs to enhance the performance, stability, and seсurity of its flagship Chrome browser. Major version upgrades also improve the browsing experiеnce with new fеatures and hidden experimental flags.
Chrome updates itself to the latest version within a few days after release to ensure you don’t miss anything. But you can also initiate an update manually to get up to speed faster.
However, if the Windows version of Chrome fails to update on its own, hangs during a manual update, or throws out an error code, here are several likely reasons:
- Network-related problems
- Compatibility issues
- Incorrectly configured Google Update Service
- Malicious extensions and browser hijackers
- Corrupt or missing files
In most instances, you can identify the problem behind a failed Chrome update by accessing the About Chrome screen (open the More menu and select Help > About Google Chrome). For example, an error message with codes 3, 11, 7, and 12 indicates complications with network connectivity.
The solutions that follow can sort out most update-related issues in Google Chrome on Windows. It’s best to quit and relaunch the browser as you work your way through each fix.
Exit Chrome and Restart Computer
Restarting your PC alone can resolve many minor bugs and glitches that randomly pop up and prevent Chrome from updating. So do that now and attempt another Chrome update before moving onto the rest of the fixes.
Run the Built-In Network Troubleshooters
Suppose a failed Chrome update points at a faulty internet connection or access point. In that case, running the built-in network-related troubleshooters in Windows may help you diagnose and fix when Chrome is not updating.
1. Open the Start menu and select Settings.
2. Select Update & Security.
3. Switch to the Troubleshoot tab.
4, Select Additional Troubleshooters.
5. Run the Internet Connections troubleshooter.
6. Perform the recommended suggestions to fix issues detected by the troubleshooter.
7. Scroll down the Additional troubleshooters screen and run the Incoming Connections and Network Adapters troubleshooters.
Flush the DNS Cache
An obsolete Domain Name System (DNS) cache stops Chrome from connecting to Google’s update servers. Clearing it should help fix that.
1. Press Windows + X to open the Power User Menu. Then, select Windows PowerShell (Admin).
2. Type the following command and press Enter:
ipconfig /flushdns
3. Exit Windows PowerShell.
Renew Your Computer’s IP Lease
If you experience spotty internet connectivity throughout Chrome, try resetting the IP (Internet Protocol) lease for your PC.
1. Press Windows + X and select Windows PowerShell (Admin).
2. Execute the following commands one after the other:
ipconfig /release
ipconfig /renew
3. Exit Windows PowerShell.
Reset Router & Network Settings
If Chrome continues to run into issues connecting to or downloading from Google’s update servers, try resetting the router. If that fails, you must reset the network settings in Windows.
Disable or Reconfigure Compatibility Mode
If you’ve configured Chrome to run in compatibility mode for Windows XP or Windows Vista, you can’t update the browser since Google no longer supports both operating systems. Deactivating compatibility mode (or selecting Windows 7 or later) can help fix that.
1. Right-click the Google Chrome desktop shortcut and select Properties.
Suppose you don’t use a desktop shortcut, open File Explorer and go to Local Disk (C:) > Program Files > Google > Chrome > Application. Then, right-click chrome.exe and select Properties.
2. Switch to the Compatibility tab and uncheck the Run this program in compatibility mode for option. Alternatively, select Windows 7 or a newer version of Windows.
3. Select Apply > OK to save the changes.
Deactivate Chrome Extensions
Extensions help boost the functionality in Chrome, but they can also create conflicts and prevent the browser from updating. Try disabling them before attempting another update.
To do that, open the Extensions menu (located at the screen’s top-right corner) and select Manage extensions. Then, turn off the switches next to each active extension.
Check for Harmful Software
Failed Chrome updates can also stem from malicious extensions, browser hijackers, and other forms of harmful software.
To help you deal with that, Chrome comes with a malware scanner built right into the browser itself. Open Chrome’s More menu and go to Settings > Reset and clean up > Clean up computer to run it.
If Chrome manages to detect and remove harmful software, run a system-wide malware scan using Windows Security or a reputed third-party malware removal utility.
Look Around the Firewall Settings
If you use a third-party anti-malware utility with an integrated firewall, open its configuration pane and ensure that Google Chrome and the Google Installer (GoogleUpdate.exe) have permissions to connect to the internet.
You must also ensure that you haven’t restricted access to the following websites:
- tools.google.com
- dl.google.com
Alternatively, disabling any third-party anti-malware utilities running on your computer for the duration of an update may also help.
If you use Windows Security only, look around the Windows Firewall’s rules and settings to confirm that nothing’s amiss.
Reconfigure the Google Update Service
Chrome relies on a background service called the Google Update Service to apply updates automatically. If it consistently fails to do that (as in, you can only update the browser manually), you must configure the service to start alongside the operating system.
1. Press Windows + R to open the Run box. Then, type services.msc and select OK to bring up the Services applet.
2. Locate and double-click the entry labeled Google Update Service (gupdate).
3. Set Startup type to Automatic.
4. Select Apply > OK to save the changes.
5. Locate and double-click Google Update Service (gupdatem) and repeat steps 3–4.
6. Restart your computer.
Reset Google Chrome
If the fixes above failed to resolve Chrome not updating, you must reset Chrome. That should resolve any corrupt or conflicting configurations preventing the browser from updating. You won’t lose personal data such as bookmarks, history, or passwords, but we recommend syncing your data to a Google Account (if you haven’t already) as a precautionary measure.
To reset Chrome, open Chrome’s Settings pane and go to Advanced > Reset and clean up > Reset all settings to defaults. Then, select Reset settings confirm.
Reinstall Google Chrome
If resetting Chrome didn’t help, you must reinstall it from scratch. Not only does that install the latest version of the browser, but the procedure should also take care of any corrupted or missing files preventing Chrome from updating going forward.
Since you’ll lose all data, you must sync your bookmarks, passwords, and settings to a Google Account. Then, go to Start > Settings > Apps and Features and select Google Chrome > Uninstall.
Follow by deleting all remaining folders from the Chrome installation in the following directory:
- Local Disk (C:) > Program Files > Google > Chrome
Once you’ve done that, download the Chrome installer stub or the standalone installer and launch it to re-install Google Chrome.
Update the Operating System
Updating Windows itself helps fix known system-related bugs preventing Chrome from working or updating normally. If you haven’t done that in a while, try applying the latest operating system updates now.
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 the operating system.
Chrome Fully Up-to-Date
Keeping Chrome up-to-date guarantees you the best version of the browser at all times, so taking the time to fix any update-related problems is well worth the effort. However, that doesn’t stop the browser from being a resource hog.
So if you’re willing to try out something new (or if Chrome continues to fail to update), check these lightweight Chromium browser alternatives instead.
