Why is Windows Vista 64-bit 15 Gigabytes?

Why is Windows Vista 64-bit 15 gigabytes in size? Windows XP is only about 1.5 gigabytes in size. What takes so much data in this operating system in order to get it to work?
 
When simply right clicking for the properties on the XP Windows folder here with only a few programs besides video and sound installed 2.93gb for size and 2.71gb for size on drive is seen. The newer version after this many years is obvoiusly going to be larger as XP is larger then previous versions of Windows itself.

9x-ME, NT was never anywhere near as large as XP. And what is the main difference between 16, 32, and 64bit? Not simply memory capacity but seeing larger partitions. With the new 1tb drives now seen and larger to come the 64bit structure and of course all the newer features(eye candy) that bloat up the new version.
 
32-bit Vista can manage as large partitions as the 64-bit edition can

No one said it couldn't. 98 being the first 32bit besides NT 3.1 is supposedly able to run on a 2tb partition in theory. MS plans to dump the 32bit architecture entirely following the next version of Windows due out in the 2009-10 time frame.
 
2TB is also limit of the MBR partitioning scheme. If the drive gets bigger, other methods must be used. That goes for 64-bit Oses also
 
MS as well as partitioning software companies will have to address that issue once the available of 2tb+ drives is there or a new type of drive maybe non magnetic will be seen for that. The main problems seen is that hardwares see progress at a faster pace then OSs and softwares do.
 
They have already addressed it. If you combine multiple drives in raid arrays then 2TB is not that much anymore
 
2TeraByte Disk Size barrier -- 32bit FAT http://www.linux-1u.net/Disks/

Recommended minimum volume size is approximately 10 MB.
Recommended practical maximum for volumes is 2 terabytes. Much larger sizes are possible.

Better scalability allows you to use large volumes. The maximum volume size for NTFS is much greater than it is for FAT. Additionally, NTFS performance does not degrade as volume size increases, as it does in FAT systems. http://www.microsoft.com/technet/wi...60b-0433-4ba1-a2f4-9338915fdb4b.mspx?mfr=true

With the revised BSD 48bit method inplace of the MBR's 32bit presently you then see a 247tb upto 272.11tb partitioning scheme there. With each new version of Windows getting larger along with drive capacities eventually you will need the extra space for the OS more then simply storing files. :eek: :P http://homepages.tesco.net/~J.deBoynePollard/FGA/os2-disc-and-volume-size-limits.html
