 ====== Fixing Troublesome Windows Updates ======
+===== Windows Update Missing from Settings =====
+Edit the Windows Registry:
+**HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> Policies -> Explorer**
+**Delete** the key: ''SettingsPageVisibility''
+===== CLI =====
+The first thing to try if Windows Updates fail is:
+<file>
+sfc /scannow
+</file>
+If it doesn't complete, try something like:
+<file>
+chkdsk /x /f /r
+y
+shutdown now -t 0
+</file>
+then:
+<file>
+dism /online /cleanup-image /restorehealth
+sfc /scannow
+shutdown now -t 0
+</file>
+<note tip>If Windows Update fails to install an update, try downloading the update from the Microsoft Update Catalog and installing it locally.  https://www.catalog.update.microsoft.com</note>
+===== WUReset.bat Script =====
+FIXME This didn't work on Windows Server 2016, but the concepts do.
+Run as an administrator:
+<file>
+@ECHO OFF
+echo Simple Script to Reset / Clear Windows Update
+echo.
+PAUSE
+echo.
+attrib -h -r -s %windir%\system32\catroot2
+attrib -h -r -s %windir%\system32\catroot2\*.*
+net stop wuauserv
+net stop CryptSvc
+net stop BITS
+ren %windir%\system32\catroot2 catroot2.old
+ren %windir%\SoftwareDistribution sold.old
+ren "%ALLUSERSPROFILE%\application data\Microsoft\Network\downloader" downloader.old
+net Start BITS
+net start CryptSvc
+net start wuauserv
+echo.
+echo Task completed successfully...
+echo.
+PAUSE
+</file>
