Font size suddenly very small

When I was typing an email the font size suddenly became very small within the email and within every aspect of my Windows 10. I have been unable to return it to its normal size. I cannot even respond to an email because the type is so tiny I cannot even
read it. If I try to enlarge the type it only lasts for a few seconds before becoming tiny again. What can I do?

Windows Update suddenly hangs?

Windows Update is suddenly hanging for some reason... I went and downloaded and installed the first bunch of updates, restarted when asked, and now when I go back to windows update I just get the window with a white box forever. Reboot and it still does it. This happens to be on my main machine, running windows 7.

I've also noticed when I reboot it says configuring windows update, step 3 of 3, 47%. Maybe it somehow skipped something and is screwed forever?
