Security Notice

Your antivirus may flag KMSPico during download because it modifies system files during activation - this is normal behavior for activation tools. We verify all downloads are 100% clean with VirusTotal. For activation to succeed, you'll need to temporarily disable your antivirus or add KMSPico to its exclusions list.

"After wasting money on shady key sellers, KMSPico worked perfectly on my Windows 11 laptop. Activated Office 2021 too. The whole process took less than a minute. Just remember to disable antivirus temporarily!"

Frequently Asked Questions

Everything you need to know about KMSPico

Is KMSPico safe to use?

Yes, when downloaded from our official site, KMSPico is completely safe. The false positives from antivirus programs occur because KMSPico modifies system files during activation - the same behavior some viruses exhibit, hence the detection. We scan all files with VirusTotal before release.

How is KMSPico different from buying a license?

KMSPico doesn't use product keys. Instead, it emulates Microsoft's enterprise activation servers locally. While retail keys activate directly with Microsoft, KMSPico makes your system think it's activated through a corporate KMS server. The end result is similar - full access to all features without paying for a license.

Will Microsoft ban me for using KMSPico?

In our decade of experience, Microsoft doesn't ban personal accounts for activation methods. They primarily target businesses using unlicensed software. However, we always recommend purchasing genuine licenses if you can afford them, especially for business use.

Why does activation sometimes fail?

Common causes include: (1) Not running as administrator, (2) Antivirus blocking the process, (3) Corrupted system files, (4) Trying to activate pirated Windows/Office copies. Our troubleshooting guide above covers solutions for all these scenarios.

Can I update Windows/Office after activation?

Yes! KMSPico activations persist through updates. Major version upgrades (like Windows 11 22H2 to 23H2) might require reactivation, but regular monthly updates won't affect your activation status.

Is there a mobile version for Android?

No, KMSPico only works on Windows PCs. Android activation tools with similar names are fakes that often contain malware. Only download KMSPico from trusted sources like this website.
