Hi, Khurshid Tarapore
To change the font size in Windows 8:
- Right-click on the Desktop and select Screen resolution.
- In the window that opens, click on "Make text and other items larger or smaller".
- Choose the text size you want: Smaller (100%), Medium (125%), or Larger (150%).
- Click Apply, and you'll be prompted to sign out and sign back in for the changes to take effect.
That should adjust the font size for most things on your computer.
