Hi Ernest.
It depends on where you are experiencing the reading problems in Windows, there are a few avaialble options..
1
If this problem is in an app like a web browser or Outlook, in the app, press Ctrl and press the plus key on your keyboard to zoom in, does that increase the size of the text...etc. in the app?
2
If not, open the Settings App.
Go to Accessibility - Test Size.
Try using the slider on that settings window to increase the test size, this should increase the test size in all apps.
3
Or, right click your Desktop and select 'Display Settings'.
On that window is a Scale setting, try adding to the Scale percentage, that should increase the size of everything on oyur screen.
