Size of Windows 10 on SSD

[F1demon]

Having just installed Windows 10 on my new SSD, I notice that of the total 240GB available, I now have just 206 GB!? Doing a quick check through >Properties I find that all the data on the drive which is so far, just Win 10 9I haven't stored or added any apps to the drive) is taking up approx 17 GB (15GB on disk) but the Space Available is 206 GB??

Where is the remaining 17 GB going? Should't it have 223 GB available instead? Does Win 10 really take up so much space??

Thanks!

When formatted the 240gb SSD is only about 223GB , there's your other 7gb.

Did you do a clean install or is this an upgrade from older OS?

If you have the option to hibernate then that takes up as much space as you have for memory, there is also the allocated amount for system restore and prefetch cache. This things will easily add up to over 7GB.

I did a clean install. NTFS, 0 partition. I created a bootable usb using Win10 on my existing C drive then used that to install on the Hectron SSD.

Ok, so you don't have any windows.old folders with a clean install.

You have the simple fact that 240 GB is really only 223 GB, so that means your OS is taking 17GB which is very spot on, even more so when you factor in like I said any virtual memory, hibernation, prefetch, and System Restore.

You can lookup how to reduce virtual memory, disable hibernation and reduce or turn off system restore.
Now If you are not backing up the entire computer to another machine (like a full disk image) then I would not recommend turning off system restore.

Run Windirstat.

Look for hidden files:
hiberfile.sys
pagefile.sys
swapfile.sys
Also windows install makes separate partitions for bootloader, recovery environment and reserves some additional space for future needs.
You can check it in Disk Management.

Yes, but where is the extra 17GB going? I have just 206 GB available?

As boosted1g said, disk makers use it so that 1GB is 1,000,000,000 Bytes.
Computers see 1GB as 1,073,741,824
So 240GB disk is seen as 223GB disk.
206GB +17GB=223GB

Edit:
The difference why Computers see 1GB as such, is due to the fact that since ancient times, computers used binary (and still do) which made it a LOT more simple to define that 1k is 1024 and 1M is 1024*1024 and 1G is 1024*1024*1024

In short, if space used is 17GB and free space is 206GB and your disk is 240GB disk, you do not have missing space. same 1024 vs 1000 applies to ALL storage mediums.

Did you run Winderstat.

223gb is the formatted size of a 240 gb SSD
-16 to 20 gb for 64 bit install of OS
= 207

Your fine.

Where do I look in Disk management?

So, what ure saying is that because of 1 KB = 1024 Bytes - the actual size on disk should be more than the absolute value reflected, whereas, when I check disk size thru Properties it states, "Actual size on disk" = 15GB & "Used space" = 17GB which is the opposite? What am I getting wrong here?

https/windirstat.info/
Run Windirstat.

It states 1.4 GB for the hibernation file and 1.6 GB for recovery.
