Buy OEM if this is a fixed office desktop that will run untouched until it is scrapped. Buy retail if you upgrade hardware, build your own PCs, or want the option to move the licence later. See the OEM version here.

What you receive

  • Your Windows 11 Pro retail product key (25 characters)
  • Step-by-step activation instructions
  • Official Microsoft Windows 11 ISO download link
  • GST invoice as a PDF attachment
  • WhatsApp number for activation support

Delivery time: Instant Email Delivery and Whatsapp.

Will Windows 11 run on your PC?

Check before you buy. Windows 11 requires:

  • TPM 2.0 enabled in BIOS
  • Secure Boot capable
  • A supported processor (Intel 8th generation or newer, AMD Ryzen 2000 or newer)
  • 4 GB RAM and 64 GB storage minimum

To check: press Windows key + R, type tpm.msc and press Enter. If it reports a TPM is ready for use, you are fine. Many PCs have TPM 2.0 switched off in BIOS by default — if it says no TPM found, enable it in BIOS before assuming your hardware is unsupported.

If your PC genuinely cannot run Windows 11, do not buy this key. Windows 10 Pro is the option for older hardware.

How to activate

  1. Open Settings (Windows key + I)
  2. Go to System, then Activation
  3. Expand Change product key and click Change
  4. Enter the 25-character key from your email
  5. Click Next, then Activate

The Activation screen should then read “Windows is activated with a digital licence linked to your Microsoft account.”

Moving the licence to a new PC later

Sign in to Windows with a Microsoft account before you transfer — this links the digital licence to your account and makes reactivation far easier.

  1. On the old PC, open Command Prompt as administrator and run slmgr /upk to remove the key
  2. On the new PC, enter the same key in Settings, System, Activation
  3. If it refuses, run the Activation Troubleshooter and choose “I changed hardware on this device recently”

Message us on WhatsApp if it does not go through — we handle transfers as part of the original purchase, not as a new sale.

If activation fails

Send us a WhatsApp message with a screenshot of the error and your order number.

For business buyers

GST invoice with our GSTIN issued in your company name, so you can claim input tax credit. Enter your business name and GSTIN at checkout. For more than five licences, contact us for volume pricing at WhatsApp : +919311776999.

Frequently asked questions

Is this a genuine Microsoft retail licence?

Yes.

Can I upgrade from Windows 11 Home to Pro with this key?

Yes. Enter the key in Settings, System, Activation, Change product key. Windows upgrades the edition in place and your files and installed programs stay untouched.

Do I need to reinstall Windows to use this key?

No. If Windows 11 is already installed, just enter the key. A clean install is only needed if you are moving from Windows 10 or setting up a new machine.

How many times can I transfer this licence?

Once.

Does it work with a local account, or do I need a Microsoft account?

It activates with either. A Microsoft account is recommended because it links the digital licence to you, which makes future transfers and reinstalls much simpler.

    I was a bit skeptical about glamtechenterprises.com because i never heard about it before and came her because of google search. Had a small chat with customer care executive about my doubts and as per his assurances I went forward and did the transaction. Purchased Windows 11 Pro Retail Key and everything went smoothly – from transaction to upgrading my Window 11 Home to Windows 11 Pro. Thanks a lot for the support and product. Kudos to you guys for providing authentic products at low price.
