WSUS reduce disk space

Reference:
How To Clean Up WSUS

我的 WSUS server C:\ 被塞滿了，檢查發現 WsusContent 目錄有 120GB。
先用 WSUS 的 Server Cleanup Wizard，跑完後完全沒有縮小！
找到上面那一篇的方法重抓 WSUS 資料後只用了 17GB。

步驟：
1. 將 Automatic Approvals 停掉
2. 刪除 C:\WSUS\WsusContent 目錄下所有的檔案
3. 執行下面這一段 batch file，重設 WSUS database

net stop wsusservice
cd "C:\Program Files\Update Services\Tools"
wsusutil.exe reset
echo Delete WSUS Folder Content
pause
net start wsusservice

4. 在 WSUS 執行 Synchrozine Now
5. Open PowerShell ISE as Administrator and run the script

#Change server name and port number and $True if it is on SSL

$Computer = $env:COMPUTERNAME
$Domain = $env:USERDNSDOMAIN
$FQDN = "$Computer" + "." + "$Domain"
[String]$updateServer1 = $FQDN
[Boolean]$useSecureConnection = $False
[Int32]$portNumber = 8530

# Load .NET assembly

[void][reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")

$count = 0

# Connect to WSUS Server

$updateServer = [Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer($updateServer1,$useSecureConnection,$portNumber)

write-host "<<<Connected sucessfully >>>" -foregroundcolor "yellow"

$updatescope = New-Object Microsoft.UpdateServices.Administration.UpdateScope

$u=$updateServer.GetUpdates($updatescope )

foreach ($u1 in $u )

{

if ($u1.IsSuperseded -eq 'True')

{

write-host Decline Update : $u1.Title

$u1.Decline()

$count=$count + 1

}

}

write-host Total Declined Updates: $count

trap

{

write-host "Error Occurred"

write-host "Exception Message: "

write-host $_.Exception.Message

write-host $_.Exception.StackTrace

exit

}
