Two views of Drive C:\ :-
The "internal" view on the right shows MOST files, but not all, only those that Windows Explorer can show you.
MOST files excludes any folder to which you are denied rights, e.g. other users profiles,
and also things that only defragmenters can see, such as MFT zone and Metadata (dont know what that is, I only know that it is),
and also possibly other things I know nothing about, which would make my head hurt worse.
These MOST files have an artificial "size" of 7 GB which would be consumed if they were NOT NTFS compressed,
These MOST files have a genuine "Size on Disk" that shows they consume
6,266,238,039 bytes
The "external" view on the left shows the actual storage consumed as used space,
6,741,970,944 bytes.
6,741,970,944 - 6,266,238,039 = 475,732,905 bytes more than Explorer will show me.
I have a 160 GB drive of which only 15 GB is allocated to C:\, and only 6 GB is used, with 475 MB un-shown files
You live on a much grander scale - perhaps 10 times on everything,
and I would estimate that if everything I had was 10 times larger, I would have a 4.75 GB discrepancy,
so your 8 GB discrepancy seems not unreasonable.
Finally, I use 32 bit XP Home edition with SP3, which I understand on limited hardware can RUN, where Vista can only CRAWL,
so perhaps Vista has given you a lot more semi-visible no-file luggage than XP does.
I am not sure, but I think the MFT zone is proportional to the size of the partition.
