Non win7-sys apps open only tiny window & text

JamesEJ,
If I might offer some steps that have nothing to do with your issue...
...but might make things easier for us to help you:

open MS Paint
scroll to the bottom of the white area
scroll to the right of the white area
shrink that white area by dragging the bottom right corner of the white area up to the top left corner.

Leave an area that is about one inch square.



Close MS Paint. When prompted to save your changes, select Don't Save.



The next time that you open MS Paint, the white area should be small.

The next screenshot that you paste in should have no white areas around it.

It will look much better in forum posts

Ok, checked what was going on with TeamViewer. As suspected there was nothing wrong with the text and windows but they were too small for the OP due to personal reasons.

DPI was set to 150% already so I decreased the resolution to 1440x900 (worked best for the OP in terms of readability).
For future reference:
Screen resolution - Screen Resolution - Display Settings
DPI settings - DPI Display Size Settings - Change

In case if you ever need - Magnifier - Magnifier Starts at Startup - Enable or Disable

I concur with GokAy in principle, who was very professional, courteous and helpful on TeamViewer. The results were much more than just great for the local PC resolution subject of this thread. It does feel very good to have someone on your computer that is obviously honest (YOU ALL KNOW>rather than just trying to sell something with scare tactics). GokAy is a substantive positive contributor to this forum and Windows 7.

GokAy I personally thank you publicly for your unsupervised outstanding performance!!
