If online activation fails for your Windows operating system or Microsoft Office product, you can use the phone activation method. Here’s a step-by-step guide:

Step 1: Access the Activation Window

For Windows:

1. Right-click on the Start button and select “System”

For Office:

1. Open any Office application (like Word or Excel)
2. Go to File > Account
3. Click on the “Change Product Key” button

Step 2: Start the Phone Activation Process

1. In the activation window, look for an option that says “Use the automated phone system” or “Activate by phone”
2. Click on this option to proceed

Step 3: Choose Your Country/Region

1. You’ll see a list of countries/regions
2. Select your location from this list

Step 4: Get the Installation ID

Step 5: Call the Activation Hotline

1. A toll-free number for your region will be displayed
2. Call this number from any phone

Step 6: Provide the Installation ID

1. When prompted, enter or speak the Installation ID you wrote down
2. Follow any additional prompts or instructions given by the automated system

Step 7: Receive the Confirmation ID
