Does anyone have recommendations of good magnifying glass app for a Windows PC ?
I do a lot of screen share work and getting a bit tired of squinting at the fine print by the time I see things on my PC. I am checking things out in Google but am leery of downloading something without some recommendations.
It comes with Windows. Just push Start and type Magnifier.
Or just use the zoom on your phones camera, works for me at restaurants. 
In my Windows 7, just hold down the Windows logo key and press + , a magnifier will automatically open, which will follow your pointer around the page and can be zoomed in or out using the WKey with + or -.
Cool. Works with Windows 10 too!
You can also enlarge or shrink many applications by holding down the Ctl key and rotating the knurl knob on the mouse.
