Download, Install, and Activation Guide

Getting started is straightforward—follow these steps to download, install, and activate your Windows 8.1 Professional OEM.

1. Download:
   • Visit the official Microsoft website (microsoft.com) or your licensed OEM provider’s portal.
   • Sign in with your Microsoft Account and enter your 25-character product key to access the download.
   • Choose the 32-bit or 64-bit ISO file based on your hardware. Save it to a USB drive or DVD for installation (use tools like Rufus for USB creation).
2. Install:
   • Boot from your installation media: Restart your PC, enter BIOS/UEFI settings (usually F2, Del, or Esc), and set the USB/DVD as the first boot device.
   • Follow the on-screen setup wizard: Select language, enter your product key (or skip for later), choose “Custom: Install Windows only” for a clean install.
   • Partition your drive as needed, then let the installer copy files and restart (this takes 20-60 minutes).
   • After reboot, complete initial setup: Create a user account, connect to Wi-Fi, and customize privacy settings.
3. File > Account > Activate Product:
   • Once installed, open the Settings charm (hover over top-right corner or press Windows + I).
   • Go to Change PC Settings > Update & Security > Activation (or search for “Activate Windows” in the Start Screen).
   • Select Activate and enter your product key if not already done during install.
   • If prompted, sign in with your Microsoft Account to link the license—this enables automatic updates and recovery options.
   • Troubleshoot via slmgr /ato in an elevated Command Prompt if activation fails (e.g., due to hardware changes). For OEM keys, activation is tied to the motherboard—contact Microsoft Support if issues persist.

Your Windows 8.1 Pro will be fully activated and ready for updates via Windows Update. Enjoy a secure, efficient OS that powers your professional workflow! For support, visit support.microsoft.com.
