Rules of the Road for Safe Patching

Rules of the road for safe patching

Monthly security patches ship on the second Tuesday of each month (Patch Tuesday).

For all versions of Windows, defer them for at least 15 days. That should give Microsoft time to identify and fix any significant oopses. The exception is the rare urgent threat — in which case, we'll tell you to install an update sooner than later. (Check out our AskWoody.com posts on the days following Patch Tuesday.) Another exception: Security patches may also contain nonsecurity fixes. In some cases, you might want to install a security update sooner when it includes a feature fix you really need.

Microsoft also sends out preview updates, typically on the third Tuesday of each month. They are completely optional, and we recommend skipping them. We will list them in the next Patch Watch column following their release because Microsoft typically doesn't label them as previews (bad dog!).

Updates can be deferred on Window 10 Pro and above. If you're running Win10 Home, we recommend upgrading to Pro.

Ensure that Windows 7's patch-update setting are set to download or check for updates, but don't automatically install them. It's your best defense against problematic patches.

Other rules

Never install hardware drivers -- unless you get them from the computer's manufacturer

Never install an update to a newer version of .NET. Let your applications set the .NET versions they need If you are offered .NET 4.8, skip it.

For business, I recommend being on 1903 at this time and deferring 1909 Version 2004 Sheet updated: 7/14/2020 >>>> Should be installed as of June 30, 2020 for business patchers Known issues page: https://docs.microsoft.com/en-us/windows/release-information/status-windows-
