5 Reasons to Use a Genuine Windows Key
Many users are tempted by free keys online or YouTube tricks. But using those comes at a big cost. Here’s why a genuine license is non-negotiable:
1. Security That Lasts
Cracked keys usually disable security updates. This puts your files, system, and privacy at risk.
2. No Interruptions
A genuine Windows experience is smoother — no popups, limited features, or warnings.
3. Legal Assurance
Pirated software is illegal and can get you into trouble — especially if you’re running a business or professional use case.
4. Access to Support
MS only supports licensed software. With a genuine key, you get help when needed.
5. Long-Term Value
With the right key (OEM or Retail), you can use it for years without any issues.
