How to change the colour of the highlight of selected text in
by Phil Jones Computers
A customer asked for the highlight of selected text in Windows 10 to be
a darker shade of blue. The default in Windows 10 is a lighter shade of
blue for the highlight (aka text selection background) and white for
the selected text. The customer said there was not enough contrast
between the two and asked for it to be more like it was in Windows 7.

message in the Header Pane.
How to do it in Windows 10
In Windows 10, the registry keys in My
Computer\HKEY_CURRENT_USER\Control Panel\Colors are disregarded by
system. They are still there, presumably for compatibility with old
programs, but their values are not observed by Windows 10. That is why
the Advanced Appearance dialog has been taken away; these
are now ignored so there is no reason for the
dialog to exist.
Instead, a theme file is read to obtain the necessary settings. The
advantage of a theme file is that it is readily sharable. So a theme
designer can compose new colours for the Windows 10 desktop and the
user can install them via "Get more themes online" without having to
import registry values. The disadvantage is taking away the user's
ability to customise all of their Windows desktop colours.
Therefore... here is a little theme file to bring back
old-Windows-alike white text on blue background selected text.
