A number of my users have contacted me
with a surprising complaint about Windows:  “suddenly everything's
too [big][small]!”  They may have icons that are the wrong size,
fonts that are the wrong size, even an entire screen.  I'll share a
few of my suggestions; those who read this blog may add others.
If the fonts are too large, on a
Windows 7 Desktop that's otherwise normal, most technicians will zero
in on Display Properties (which can be quickly accessed by
rightclicking the Desktop and selecting Personalize from the
drop-down menu).  That's absolutely the right place to start; when
the Personalize window comes up, look for the Display link near the
bottom.  That gives you the window with the radio buttons for
different font sizes.  But if that does not give an immediate
satisfactory result, know this: fonts are also very sensitive to
screen resolution. You will want to try a couple of different screen
resolutions.  The Personalize window also has an option to set a
custom text size / DPI.
For icons, there a very quick fix that
you should try if the user has a mouse with a scroll wheel: leftclick
a blank part of the Desktop and hold the left mouse button down;
then, (presumably with your other hand) hold down the Ctrl key, and
use your middle or ring finger to move the scroll wheel.  In Windows
7, that should make the icons larger or smaller.  
Icons, like fonts, don't handle it
well when the screen resolution changes.  And screen resolution can
change for a number of counterintuitive reasons; e.g., when the user
goes to a particularly-uncooperative website that their browser
cannot display automatically, or when a new monitor is introduced. 
So adjusting screen resolution is a good first step for icon-size
complaints.  
Then there's the user who says
something like, “EVERYTHING's too big!  I can only see part of the
screen!”  Odds are, that person has accidentally launched Windows
Magnifier.  Rightclick a blank part of the Desktop, select
Personalize, then click the Display link (when you find it after
crawling down through the enormous Desktop).  There's a link to
Magnifier on that window.  When you click that link, an animated
magnifying glass icon will come up (sometimes VERY slowly).  It will
have a “-” button to zoom out (what your user probably needs),
and a “+” button to zoom in.
Here's one more situation you might
hear about, which isn't a size issue, but is another Altered State of
Windows Consciousness users sometimes experience:  “Windows is
upside- down!”  (or rotated 90°
left or right).  The key combination is Ctrl+Alt+[arrow key for the
direction you want].  So, if the Desktop is upside-down, it's
Ctrl+Alt+^ [up arrow].  The screen will go black momentarily, then
come up flipped rightside-up.  That Ctrl+Alt+ sounds familiar, right?
 That's my theory on how it happens: a user is trying to use
Ctrl+Alt+Del and one of their fingers accidentally hits an arrow key.
 So that's how you fix that.
