即使 WindowsUpdateService 已启动并正在运行，Windows 更新 UI 仍卡在遇到错误

【中文标题】即使 WindowsUpdateService 已启动并正在运行，Windows 更新 UI 仍卡在遇到错误

【英文标题】：Windows Update UI stuck on Error Encountered even when WindowsUpdateService is up and running

【发布时间】：2022-01-12 22:05:08

【问题描述】：

我需要从 CMD/PowerShell 实现禁用/启用 Windows 更新。 为此，我使用以下命令禁用 WindowsUpdate：

sc config wuauserv start= disabled
sc stop wuauserv

为了启用，我使用以下命令：

sc config wuauserv start=auto
net start wuauserv

问题是在 WindowsUpdate 服务重新启动后，UI 仍然卡住（在重新启动后也是如此）并且 Windows 不会扫描或安装新更新，直到我手动单击“重试”按钮

是否有任何 CMD/PowerShell 可以将 Windows 更新状态恢复正常？ （不点击重试按钮）又名：

【参考方案1】：

我很确定让 Windows 更新代理搜索更新应该可以清除 UI 中的错误。这应该为您做到这一点：

$WUSess = new-object -ComObject Microsoft.Update.Session
$Searcher=$WUSess.CreateUpdateSearcher()
$SearchResults = Try$Searcher.Search("IsInstalled=0 and Type='Software'")Catch[pscustomobject]@'Updates'=@()

这是我用来通过 Windows Update 安装更新的较大脚本的一部分，而无需单击 UI。整个脚本在这里：

#region UACElevation
# Elevate UAC if not already running As Administrator
# Get the ID and security principal of the current user account
$myWindowsID=[System.Security.Principal.WindowsIdentity]::GetCurrent()
$myWindowsPrincipal=new-object System.Security.Principal.WindowsPrincipal($myWindowsID)
 
# Get the security principal for the Administrator role
$adminRole=[System.Security.Principal.WindowsBuiltInRole]::Administrator
 
# Check to see if we are currently running "as Administrator"
if (!$myWindowsPrincipal.IsInRole($adminRole))

    # We are not running "as Administrator" - so relaunch as administrator
    # Create an encoded string to re-launch the script bypassing execution policy
    $Code = ". '$($myInvocation.MyCommand.Definition)'"
    $Encoded = [Convert]::ToBase64String([Text.Encoding]::Unicode.GetBytes($code))
   
    # Indicate that the process should be elevated
    Start-Process PowerShell.exe -Verb RunAs -ArgumentList "-EncodedCommand",$Encoded
   
    # Exit from the current, unelevated, process
    exit
