Win10 KB4523786 – Uninstall It

By

Cumulative update for Autopilot in Windows 10 version 1903: October 22, 2019 was erroneously offered to all 1903 PC’s.
The folks over at AskWoody have been all over this:
First “The Patch Lady” wondered, “On a standalone PC that’s never seen Windows autopilot I am getting KB4523786 pushed out if I click on check for updates. And I have never installed autopilot here. (proving once again NEVER ever click on check for updates).”
Speculation and answers came in the comments on that post.
The following day a Microsoft Employee posted this: “A Windows Autopilot update, which was targeted as part of the out of box experience for new devices, was incorrectly offered to customers running Windows Home edition during regular scheduled Windows update scan. Once we became aware of the issue, we stopped distribution of the update. No action is required on your part.”
That is bullsquat. If you’re on 1903 and you checked for updates on Patch Tuesday then Microsoft installed or altered 90-ish files on your PC. Uninstall it.
Control Panel > Add Remove Programs > View Installed Updates > find KB4523786 and double-click it.
or you can run this from an Admin Command Prompt:
wusa.exe /kb:4523786 /uninstall /quiet /norestart
See: Microsoft pushes, then yanks, rogue kinda-security patch KB 4523786, ostensibly for Autopilot

Bad Win10 1903 Update

By

There are reports around the web that the latest update for Win10 1903 is causing Cortana to have abnormally high CPU usage:
August 30, 2019—KB4512941 (OS Build 18362.329) is the update in question.
Solutions and “workarounds” include registry editing and deleting of files. IMHO this is utter folly. The solution is this:
1 – Uninstall KB4512941.
2 – Pause updates for a month or so.
(Settings > Windows Update > Advanced Options > Pause Updates > Pause until > max time)
3 – Wait for Microsoft to fix it.
If you’ve not installed KB4512941 yet then just do steps 2 & 3.
If you are using Windows 10 Home. I’ve repeatedly said to upgrade to Pro. IT IS CHEAP

Windows lifecycle fact sheet – “The lifecycle begins when a product is released and ends when it’s no longer supported.”

Windows 10 and reserved storage
“Starting with the next major update we’re making a few changes to how Windows 10 manages disk space. Through reserved storage, some disk space will be set aside to be used by updates, apps, temporary files, and system caches. Our goal is to improve the day-to-day function of your PC by ensuring critical OS functions always have access to disk space. Without reserved storage, if a user almost fills up her or his storage, several Windows and application scenarios become unreliable.”
