This script is detected only by Kaspersky; the rest of major vendors didn't flag it as malicious?
Should I use it?

If even one reputable antivirus flags a file as malicious, it's better to err on the side of caution and not use it. It's possible that other vendors haven't updated their database yet.

If you downloaded it from the official site (which I won't link as some might say it's piracy), it's completely safe. I'll recommend you to use PowerShell command from the official site instead of running the script manually. You'll get the latest version and always from official source.

Before anyone starts arguing: script is 100% open source, well documented where it explains how it works and what it does. Microsoft is also well aware of the script and their support agents use it, as it was reported by the media.

It's from the officialy site directly.
It was surprised by K action; it's well-known of being permissive for cracks!

Cracks allowed when they don't harm the system, but this is different... and probably soon that script will be detected by additional antivirus firms...
I'm repeating the check by virustotal daily waiting for that; seems the rest of vendors are still in hibernation.

This isn't even a crack. This is a script that's taking advantage of Microsoft's own activation system and activates Windows using generic keys Microsoft themselves published on their website. It simply fools Microsoft activation servers by using installation ID of genuine key to obtain a digital license, and does everything without any 3rd party component.

If you don't trust the script, they wrote a guide how to do it manually:

The script was first released in 2015, not long since Windows 10 was released. Ever since the first version came out, it is hosted on GitHub (owned by Microsoft), Azure DevOps (owned by Microsoft) and their own, self-hosted git. Heck, even Copilot recommended you to activate Windows this way. 🤣

Antivirus didn't detect it for 10 years, why would they suddenly started detecting it now? It's not like it's very unpopular tool. Pretty much everyone I know is using it.

Don't worry, they aren't hibernating. They simply have no reason to detect clean and safe script. It doesn't do anything your Windows installation doesn't do during and after installation. Though, I'd expect Microsoft to flag it as malicious, but even they don't want to do that. So much... about piracy.

So it can be considered as a false positive by Kaspersky?

If you report it as FP, probably They won't change the verdict, I already found a similar situation not so long with a different risktool, and They did not change the verdict, so probably it's not an FP.

Completely.

Judging by the "threat" name, I'd say Kaspersky is bothered by KMS activation script (no one uses today). Though, activating Windows through KMS is also completely legal. They even created a guide how to create your own KMS (Key Management Service) server.

You could try reporting it to Kaspersky, but I doubt they'll care enough to mark the script safe.
It only hacks Microsoft
It certainly doesn't do that. The way it works is script contacts Microsoft's servers saying "Hey! I have a totally legit key I totally bought in a totally real shop. Can I get a digital license?" and Microsoft's servers reply "I don't care where you got it, and how you got it, here's your permanent digital license you asked for". *boom* your Windows has 100% legit digital license. 🤷‍♂️

Microsoft don't care because it want Windows to be the predominant OS worldwide; revenue comes from corporate sector

Exactly! I mean, they are still earning money on users by including ads, sponsored apps and telemetry. You're paying for Windows by using it. Bleeping Computer asked Microsoft about their support agents using MAS for activating troubled systems and they said it's totally against their policy and won't happen again. They still refuse to take the code down from their servers though. 😂

For home sector, they get their money from your data, just as Google

This must be a rather new signature on this tool by Kaspersky. This one never in its existence as far as I can remember was detected by Kaspersky. Even ESET whose PUA (not PUP) detection is quite aggressive doesn't detect this.
As mentioned by @Marko :) you should use the PowerShell command instead. BTW, I even used this tool to change my Windows edition from Pro to Enterprise because only in editions like Enterprise and Education, the group policy to disable start menu's recommend section works 🤷‍♂️

Stop pirating software.

Someone here once used a similar activation script and it turned out to be ransomware.

Open the script in Notepad, then copy-pasta the code into Co-Pilot and ask it what the script does.
