Its happen now and then, Windows will screw up their Windows Update and return with funny error code. This is a very unfortunate event where’s I need my system up and running with latest available update.
Failure to do so will expose machine to vulnerability or maybe features that might useful for daily work.
I bumped one of those error as below.
Some updates were not installed
Spending few minutes on google.com and found out that Windows Support page suggesting to download a tool named “Windows Update Troubleshooter“.
Basically, this tool will fix Windows Update that giving error code 0x80073712, 0x800705B4, 0x80004005, 0x8024402F, 0x80070002, 0x80070643, 0x80070003, 0x8024200B, 0x80070422 and also 0x80070020.
But if you are lazy enough, just download the tool from this link and run it right away.
