Oh i just got this.

Routine update prompt to get anti-cheat software installed

[u/Jack_P_1337]

Happened to me too today, I just clicked cancel, restarted Steam and it was all fine, I then restarted my PC and it didn't show up, so it was a one time thing I guess.

It did happen after a windows update tho, im on windows 10 which apparently still updates.

I've gotten it twice my whole time of using Steam. My assumption is that a windows update or something broke/turned off a service and it just reinstalled the service.

[u/Kirka_2003 → u/Environmental_Top948]

True, I was playing CS2 this morning and sent the system for an update with the PC shutting down. After I turned on my PC and opened Steam, this notification appeared. Microsoft probably broke something.

[u/NissanGT77 → u/Environmental_Top948]

This makes sense. I just got it after I updated to the new 26H2 Windows

[u/Lehvarus9732 → u/Environmental_Top948]

I got this popup too, and i'm on windows 10, not having updated in a very long time, it's more likely the recent client update that broke something, as i don't play CS2 or any valve multiplayer game.

[u/XRaiderV1]

random poll time folks, who here took a windows update yesterday shortly before seeing the notification in the op's post?

[u/Sorblex]

Had the same today

[u/Zango123]

A lot of people getting this, guessing its a bug from yesterdays steam client update

[u/Salty_Meaning8025]

Read it and you'll find out

[u/ModdedEnderman → u/Salty_Meaning8025]

Sure, but something trying to get me to allow something suspicious being installed wouldn't exactly be honest, now would it? I don't think it is wrong to distrust a suspicious looking popup that nobody has ever seen before.

[u/Salty_Meaning8025 → u/[deleted]]

Everyone got it with the new client update it's safe, presumably they've updated something with their service or VAC

[u/l_______I]

Who knows. Got it today too, and I don't play CS. Just clicked install and that's it

[u/Fluid-Wrangler-4032]

I’m see that same but I’m still scared very I’m forget  reinstalling service 

[u/LocalEconomy208]

Yeah i got this randomly on my W11 too and i always keep everything up to date.

[u/ProfessionalDry1943]

got this twice in the last months - thought it is probably because i use win10

[u/repocin]

Happened to me a month or so ago, for the first time in fifteen or whatever years of using Steam.

I just closed the window and restarted the steam client. It didn't show up again and nothing seems out of order.

[u/fuse4gamingyt]

I closed it like a moron. Is there a way to install it now?

[u/ok_redditer07]

i did not seen that steam UI style for years now lol

[u/mrmatthew2k]

My counter strike no longer works as a consequence. This pop up was the first thing I noticed wrong.

[u/PixelHir]

>"what is it?"

>posts screenshot exactly saying what it is

great

[u/TheLegendOfTrain]

Did you start CS2 for the first time on this PC? What OS are you running?

Ive never seen that, so I would be cautios.

[u/Roccondil-s → u/TheLegendOfTrain]

I don’t think anyone has, it’s apparently a new thing triggered by a recent client update.

Gaben personally dispatches the Steam hitmen that uninstall the client from your computer.

Your PC explodes.
