[iinfi]

hi all

i use windows 7 and mostly FF and Chrome n MS Outlook
is there a software which can turn the background of my
desktop
browser
webpages and
outlook

into a dark background. and also give me an option to bring it back to normal.

its not free and am not sure if it works in 7 . But powerstrip can do this. in color profiles look for 'invert gamma option'

For dark background for webpages in Firefox use Stylish extension with one of the many userstyles available at userstyles.org. The one I use is Global dark style - changes everything to DARK.
