因公司三台Windows主機原本是從Windows Update上下載更新，但最近更改了內部WSUS後就出現80072EE2的錯誤訊息，如下圖
猜測可能原本在微軟的Windows Update上看到的Patch更新，但尚未下載到本機端，就改成內部的WSUS Server，而內部的WSUS Server並沒有這隻Patch，所以導致更新失敗。
解決方式如下：
- Stop BITS(Background Intelligent Transfer Service) 及 wuauserv(Windows Update)
- Remove OR Rename Software Distr (C:\Windows\SoftwareDistribution)
- Remove SUS ID
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientId /f
- Flush DNS/Register
- Start BITS(Background Intelligent Transfer Service) 及 wuauserv(Windows Update)
- wuauclt /resetauthorization /detectnow
