I wonder if Windows 8 OS file size is smaller footprint when freshly installed? My hard disk needs a bit of cleaning? Does it work?

By smaller footprint, do you mean files on a Windows 8 system take less space? Could be a different file system cluster size, though your question isn't very clear. – Adambean Feb 22 '13 at 21:28
No, I don't mean the hard disk cluster size. I mean Windows-8 OS takes small size footprint? – Betterdev Feb 22 '13 at 21:33
Do you mean whether Windows 8 will take up less disk space right after a fresh installation, compared to when it's been used for some time? If so, then yes. That's true for any operating system, in fact. – Indrek Feb 23 '13 at 13:12

Windows 8 uses the same default cluster sizes as Windoes 7 in every offically supported filesystem.

If you are asking if Windows 8 requires less disk space to install than Windows 7, no. It's larger. For home edition it's about 25% larger.

..and larger as patches are added. – mdpc Feb 22 '13 at 21:36

Windows 8 includes a new option to delete replaced Windows Updates to reduce the size of the WinSxS folder. Run the disk cleanup wizzard and select the option "Windows Update cleanup":

After the reboot the files are deleted from the WinSxS folder.

After doing this, you can save a lot of HDD space and a reinstall is not necessary.
