ACTIVATION GUIDE

Step 1: Enter Your Key
Open Settings, go to Update and Security or System, and select Activation. Click Change Product Key to enter your 25-digit license key.

Step 2: In rare cases, if the key does not activate immediately and the system prompts you for offline or phone activation, select that option to proceed. Alternatively, press the Windows Key plus R on your keyboard, type SLUI 04 into the box, and press Enter to open the activation screen. Copy the IID or take a screenshot of it.

Step 3: Get Your Confirmation ID
You have two simple ways to get your Confirmation ID (CID):

Method A: Visit the official Microsoft visual support link at https://visualsupport.microsoft.com/ and enter your 63-digit Installation ID (IID) to generate your CID instantly.

Method B: Copy the 63-digit Installation ID (IID) from your screen and send it directly to us here in the marketplace order chat. We will process it and send your CID straight back to you.

Step 4: Complete Activation
Once you have the Confirmation ID (CID), enter those numbers into blocks A through H on your Windows activation screen, then click Activate to finish the process.
