What Is KMSAuto?

KMSAuto is an unauthorized KMS (Key Management Service) activator designed to emulate a Microsoft volume activation server.

🚨 Serious Risks of Using KMSAuto

1. Malware & Spyware

💬 Community Warnings

Reddit users warn about lingering threats and recommend fresh installs:

“Rootkits… your PC may seem fine now, but… starting over with a real copy of Windows is a good idea.”

🔚 Final Take

While KMSAuto may seem like a convenient hack, it comes with significant risks far outweighing any benefits:

1. High chance of malware infection

2. Violation of copyright law and Microsoft’s terms

3. Unstable, unsupported system

4. Ongoing vulnerabilities and potential backdoor access

Instead, invest in a genuine Windows or Office license—or explore safe, legitimate alternatives. It may cost more upfront, but you’ll gain security, legal peace of mind, and reliable access to updates.
