FAQs About KMSAuto Lite
Is KMSAuto Lite legal?
No. It violates Microsoft’s software licensing agreement. Use at your own risk.
Will I still get Windows updates?
In most cases, yes. But major version upgrades or online license verification could cause issues.
Does it provide permanent activation?
It emulates a KMS server, which reactivates Windows every 180 days, so it’s effectively permanent if left running.

Only if downloaded from the right source—and even then, there’s always a risk.

If you’re looking for peace of mind, buying a genuine license is the best way to ensure full functionality, security, and support.
