डिजिटल लाइसेंस vs प्रोडक्ट key: Windows असल में कैसे activated रहता है
रीइंस्टॉल के बाद आपका PC बिना key क्यों activate होता है, डिजिटल लाइसेंस कहां रहता है, और कब 25 कैरेक्टर अभी भी चाहिए।
Since Windows 10, activation creates a digital license — a hash of your hardware stored on Microsoft's activation servers. Reinstall the same edition on the same hardware and Windows activates itself, no key needed.
How the two relate
- •Product key → creates the digital license on first activation
- •Digital license → reactivates automatically on the same hardware, forever
- •Microsoft account link → lets a Retail license survive a motherboard swap (Settings → Activation links it)
When you still need the key
- •Fresh PC or new motherboard — new hardware ID, no existing license
- •Changing editions (Home → Pro upgrade needs a Pro key)
- •OEM license on new hardware — OEM licenses never transfer, digital or not
Buyer relevance
When you buy a key, you are buying the right to create a digital license on your hardware. A Retail key creates a license you can carry forward; an OEM key creates one welded to that machine.
Check your current state anytime with slmgr /xpr (expiration — should say permanently activated) and slmgr /dli (edition + channel).
