The KIR may not apply if your system has an integrated display adapter. But it appears to consistently apply with a hybrid or discrete display adapter.

I'm afraid this is not correct. My laptop has a single integrated Intel® HD Graphics 620 and KIR was applied a few days after installing KB5001330.

KB5001330 is a security Update, meaning KIR doesn't apply.

Right on Ed!!! That's what I thought. But KIR was applied on my system a few days after KB5001330 got installed....Go figure!!!!

I don't think it's the entire CU that the KIR reverses, just the part causing the issue. Being a CU 1330 would also contain non security changes.

I've encountered systems where KIR does and doesn't get applied. That's why I say it "may" not apply for integrated display adapters. I just booted a laptop a few minutes ago with an Intel® HD Graphics adapter and the KIR was applied. I'm not sure what criteria must be met for the KIR to be applied. When you figure it all out, let us know.

So, is it safe to install KB5001330 update now? Since I primarily use my Desktop for gaming.

No. Your system will completely explode and you'll just be sitting there with powder burns and ragged hair (...just kidding, of course you can install it). But your graphics performance may go from 144FPS to 44FPS until the KIR is applied. So you must decide if you want to risk that.

I think MS explained it in the "Known Issues" section of this thread's first page with the workaround.

I believe you're absolutely right Keith.

KIR definitely doesn't reverse the entire KB and as you said, KB5001330 also contains non-security changes, regardless if it is issued on a patch Tuesday!

Exactly!! "may" is the key word here!

It definitely does explain it!
The issue is though that I have never played any game on this PC, neither in normal mode nor in full screen or borderless windowed modes!!! But I got it....just in case I decide in the future to play...

How thoughtful of them....

Well, you can be sure that it will apply in MAY
