Microsoft Office Updates
You find Office update information here.
Most home Windows devices will receive the security updates that Microsoft published in October 2022 automatically. Windows Update takes care of that.
The updates are not delivered in realtime though, and some administrators may want to speed up the installation. This can be done by manually checking for updates, or by downloading updates from Microsoft instead.
Do the following to run a manual check for updates:
Below are resource pages with direct download links, if you prefer to download the updates to install them manually.
Windows 7 and Server 2008 R2
Windows 8.1 and Windows Server 2012 R2
Windows 10 (version 21H1)
KB5018410 — 2022-10 Cumulative Update for Windows 10 Version 21H1
Windows 10 (version 21H2)
Windows 11 Release version
Thanks, Martin, for helping me comprehend the 64 vulnerabilities, 9 critical and 5g important so I understand what I was doing when I upgraded to Windows 10 version 21H2 (OS Build 19044.2130). Up to now a smooth fast update.
I could update also to Microsoft Edge Final 106.0.1420.42 version.
So I am also lucky that my (Old) Custom installations did receive the new Microsoft Edge web browser, without the old version being removed.
Why is it taking them so long to resolve the issue with group policy preferences? Microsoft failed to hire a team with a commitment to quality. We won’t be modifying any of our group policies to fix their screw ups. As long as it’s not fixed, we’ll just keep blocking these updates.
Wjy would anyone still be using PPTP? It was compromised a decade ago.
Look at all of those, “Remote Code Execution Vulnerability” entries.
Shame on you, M$.
Fixed my trusty Win7, how niiice
It’s a testimonial to how bad Windows updates have been and remain that I am more afraid of what they might do to our fleet of PCs and servers than whatever threat they are meant to stop or mitigate. Do they actually test any of this? If they do they must have a “Meh, good enough, release it” mentality.
The same everything to get the same nothing. W11 in its pure essence.
Anyone have issues with Windows 2012 R2 KB5018474 (Security Monthly)
Windows update gets stuck when installing it.Had this issue on a few Servers.
We had the same issue with last months Security Monthly.
Always gives me a chuckle when i read one of the known issues is…
(Old) Custom installations may not receive the new Microsoft Edge web browser, while the old version may be removed.
That’s not an issue that’s a feature. 😀
Martin, I noticed that originally that Windows 10 and 11 updates would appear simultaneously, but it looks like Windows 10 22H2 will be here in October 2022 or maybe even later.
I ask this because I updated my Windows 10 o.s. yesterday but not to Windows 10 22H2.
Do you know maybe when the Windows 10 22H2 is coming?
Microsoft has not revealed the release date. Maybe it is coming on next Tuesday, but no one outside of Microsoft knows at this point.
Thanks, Martin, for your best guess.
Oct 2022 cumulative updated should be kb5018410 for Windows 10 (direct download)
Thank you, corrected!
Direct update download links still show:
Windows 10 (version 21H1)
KB5017380 — 2022-10 Cumulative Update for Windows 10 Version 21H1
Windows 10 (version 21H2)
KB5017380 — 2022-10 Cumulative Update for Windows 10 Version 21H2
Should be KB5018410
Just a warning that the October 2022 Patch Tuesday updates for Windows 10 21H1 and/or the subsequent “out-of-band” connectivity-fix update appear to have reset (undone) at least five privacy settings, so this is *not* the month to forget to re-run ShutUp10 (which, incidentally, was itself updated a couple of days ago). Moreover, the updates appear to have overwritten custom external-drive timeout settings in the Registry. [Drive timeouts could be controlled from Windows 7’s Control Panel, but Microsoft apparently felt that ordinary users shouldn’t have that degree of control over their hardware in Windows 10. If you want to change drive timeouts in Windows 10, you have to hack the Registry. Moreover, the default timeout seems to be after 5 to 8 seconds of inactivity, resulting in constant on/off cycles that kill an external hard drive faster than just leaving it running all the time. This is the kind of brain-dead move I’m beginning to expect from a company that now seems to spend more time trying to decide whether to make its OS look more like MacOS or more like Elementary than it does on what’s actually under the hood/bonnet.]
