March Cumulative Update slowdown

Is the March cumulative update meant to slightly slow down the performance (if the computer never received the January and February updates)?

Microsoft removed or delayed deployment of security updates to some Windows systems running non-compliant antivirus programs for a couple of months early in 2018 because of issues with system crashes.

Systems running Avast were not denied or blocked from receiving cumulative monthly updates.

Mine was. And I wonder if any of the slowdowns that came with the January updates exists in the March update as well.

My system is fully updated and I haven’t noticed any slowdowns.

There were issues with AMD processors. Is that the case here?

Cumulative means roundup or rollup. If a cumulative update is not installed then the entire thing will be installed, otherwise whatever is new will be installed at each month rollup.

I have a Intel processor.

Exactly. Hence my question if the March cumulative update includes anything from the January/February updates that slowed down many people’s systems (though Microsoft subsequently rolled them back).

Microsoft changed embargo policy: https://www.computerworld.com/article/3263743/microsoft-windows/microsoft-lifts-update-embargo-on-windows-10.html

I have Avast which wasn’t affected since they complied with the registry key requirement.

What slowdown ???

Cumulative means if you didn’t get Jan and Feb you’ll now get it in March.
I haven’t noticed any slowdown so don’t know what you’re after ???

Which is why I’m asking if any slowdown from January or February was included in March’s updates for those that didn’t get the former.

Was your system slowed down already after the January Spectre/Meltdown patches?

I’ve already said NO. Not that I’ve noticed.
I certainly didn’t have any instruments connected prior and after the update but,
If there is a difference, it isn’t anything that I can notice.
I’ve also read that the older the system, the greater the chance that there may be some slowdown.
My system is less than 5 years old.

If you are talking about my system slowing down after these required updates, then the answer would be no, not noticeable at all.

Any time software or firmware is changed, the possibility always exists for bugs and performance degradation.

Since Spectre requires predictive prediction corruption to operate, it would seem that software modification of a modern processor’s ability to predict possible outcomes of processing would impact newer processors more than older ones, maybe.

As to whether Spectre is rooted in hardware vulnerabilities, it is, and really the only true fix is to fix the hardware.

The effect is actually greater on older systems. If you have a fairly new system, the impact is minimal.
If your system is 5 years old or older, the impact will probably be noticeable.

Hi guys, it doesn’t make sense to discuss it (slowdowns), imo.
If security updates are available you should install them, that’s it.

Totally agree. There are those who are more concerned with speed than security.
Slowdowns usually aren’t noticed anyway. Who sits in front of their computer with a stopwatch ???

Exactly, the only reason for my question was that I did notice it.

Nothing we can fix for you.

How old is your computer ???
