User's Manual

TuneUp Registry Defrag cannot rewrite the registry when it is running, but only immediately after
Windows has started up. Now choose whether you would like to restart the computer now or
whether you would prefer to allow the optimization to run automatically next time Windows starts
up. Please note that optimization can take several minutes.
If you immediately decide against the optimization or were only interested in the analysis results from
the outset, you can exit the program by clicking Cancel.
