Microsoft’s “Patch Tuesday” occurs on the second Tuesday of each month. This is the day when, like clockwork, Microsoft releases large update packages for Windows 10, Windows 7, Microsoft Office, and its other software.
What Is Microsoft’s Patch Tuesday?
Once in a while called “Update Tuesday,” Patch Tuesday is an informal term for the day when Microsoft discharges update bundles for the Windows working framework and other Microsoft programming applications, including Microsoft Office.
As Microsoft patches security vulnerabilities, it doesn’t discharge those patches right away. Rather, the organization assembles those fixes into a bigger update, which is discharged on Patch Tuesday.
Microsoft does this to make the update procedure as unsurprising as feasible for administrators. IT experts realize that patches will show up on the second Tuesday of every month, and they can make arrangements to test or introduce them. It ought to be simpler than ceaselessly applying littler patches and more unsurprising than tremendous patches showing up on an irregular day of the month.
When Is Patch Tuesday?
Patch Tuesday occurs on the second Tuesday of each month. More precisely, it occurs on the second Tuesday of each month in North America.
Microsoft doesn’t have a guaranteed time these patches and Microsoft’s information bulletins about them will be released. These updates generally arrive around 10 a.m. Pacific Standard Time, but they may be released later in the day.
Windows 10 checks for updates about once per day. The average Windows PC should automatically download these updates via Windows Update by Wednesday afternoon if it’s powered on and connected to the internet. Of course, administrators may choose to delay and test these updates before deploying them to PCs in their organizations.
Updates Aren’t Only Released on Tuesdays
As you might have noticed, Patch Tuesday isn’t the only date updates arrive. In some cases, Microsoft will issue “out-of-band” updates for particularly critical security flaws, especially ones that are being exploited in the wild.
However, if a security hole isn’t being exploited in the wild and it’s okay to wait a few weeks, Microsoft will wait for Patch Tuesday to issue that update.
Even if you do get one or more smaller patches in a month, there’s always bigger update coming on Patch Tuesday. It contains all the updates that didn’t have to be rushed out.
Patch Tuesday Is For “B” Updates
In Microsoft’s update parlance, Patch Tuesday updates are called “B” updates because they’re released in the second week of each month.
Microsoft also issues optional update packages in the third or fourth weeks of the month. They’re known as the “C” and “D” updates. These include bug fixes and improvements for problems that aren’t security holes. After these updates are tested, their fixes make it into next month’s B update on Patch Tuesday.
These C and D updates now appear as “optional updates” in Windows Update on Windows 10.
Patch Tuesday Isn’t Just For Microsoft
Other companies have chosen to join Patch Tuesday to make things easier for system administrators to update their systems with security patches.
For example, Adobe also releases security updates for its software like the Adobe Flash Player browser plug-in and Acrobat Reader PDF viewer on Microsoft’s Patch Tuesday.
Patch Tuesday Isn’t For Windows 10’s Big Updates
Microsoft now discharges enormous updates to Windows 10 once at regular intervals. For instance, Windows 10’s last enormous update was the May 2019 Update, and it was gone before by the October 2018 Update.
These updates aren’t discharged on Patch Tuesday. They’re discharged on whatever day Microsoft chooses to discharge them.
Considerably after the official arrival of each significant update, the rollout procedure is moderate. Large updates like these may not be naturally introduced on your PC until some other time, as Microsoft now utilizes AI to decide when it’s certain the update is protected to introduce for your blend of equipment and programming. You can at present decide to skirt the pause and introduce them promptly, however Microsoft says you have better chances of a decent encounter on the off chance that you choose to pause.
That is not normal for Patch Tuesday refreshes, which don’t contain new highlights. They contain significant security updates and right now tried bug fixes. Naturally, they’re consequently introduced for all Windows clients as quickly as time permits.
