It seems that more and more developers avoid the fullscreen option. It is a really bad idea because those who use Win7 has probably grown accustomed to having two programs side by side with the Win7 built-in option.
As it sais on the title..
Boot time defrag is better and registry defrag can help a bit too :)
Junk cleaning will dramaticaly reduce defrag time and clean up hard disk too :)
It would be nice to have all these options:
auto defrag on sytem startup
do not open report after analysis/defragmentation
auto-check of updates
other style options
