I am sorry i wasn't able to explane what i actually wanted.
From System icon set I mean something like this: Ubuntu 10 IconPack Installer by ~JokerneB on deviantART
That is what i wanted but sadly its only for x86 Windows and i am on 64x.
And i don't think that the creator have any mood to create a x64 one.
And from File browser I mean 'Explorer' like windows explorer not internet browser.
