Solved! Size of Windows 10 on SSD

[saiketgs6]

Having just installed Windows 10 on my new 240 SSD, I notice that of the total 222GB available, I now have just 186 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 18 GB (17GB on disk) but the Space Available is 186 GB??

Where is the remaining 18 GB going? Should't it have 205 GB available instead? Does Win 10 really take up so much space??

look under disk management at the drive, maybe it's partitioned. there should be at least 10% left un-partitioned so the SSD can do optimization and keep performance high when it fills up. Disk Manager will tell us, post the pics please

also, get a free app called WinDirStat that will map out files on the drive and let you easily see what's on disk. remember updates to windows 10 can save off an entire windows folder to Windows.Old

if you remove the old windows folder, then you can't roll windows back if it broke something.

I hear the new Oct update this yr FIXES the Windows+Nvidia stuttering problems in games and such... hopefully

run this https/windirstat.net/ and see what's eating your system, but first check the root of C: drive for Windows.Old folder, that's usually it.

By the time you do all your updates, add in the basic items you need to surf around, a few add ins to make things run smooth, ad blocker, etc. you are looking at right in the neighborhood of 30GB. It will actually be closer to ~40 unless you go back and delete updates files, Win .old, etc.

If you look in disk manager you will note that parts of your drive are dedicated to recovery and paging files.

Windows 10 can get quite bloated.

My Dell Inspiron 7559 laptop has a 256GB SSD with. I think the C: drive has around 224GB allocated to it and I only have 188GB available. It is basically a clean install of Windows with updates.

The only programs I have installed are:
- Avast! Free
- Adobe Acrobat Reader
- FireFox
- XMedia Recode - A simple video encoder that is less than 50MB.
- Probably at most 15 saved game files for Fallout 3.

Dynamic swap file has to go somewhere. Once you get solid with install put it on large disk if speed is decent. Windows must have a memory area to use while operating. It does not need to be on primary but there will be a loss of processing speed when on second, third or whatever disk. After thinking on it for a moment an SSD is the last place you want to put accessible memory. Judging from PNY I just bought there are nnnn number of writes available. No sense and a future freeze with your SSD if the OS is constantly writing to it. The more hardware you can spread across the smoother and faster it will be. Until such point that windows starts losing track or you run into mobo limits with pointers and hierarchical levels it sees as your hardware. A final issue is how much of SSD has bad index or data areas. Those also get subtracted from drive size as they are found. Hope this helps. And as jaguarskx (mmmmm bebe) says, "Windows 10 can get quite bloated." (sweetest convertible made that cat) Win 10 is MS first effort at IoT which doubles or worse the updates as they attempt to own future connections to all the appliances you have. Will be an interesting process with new lamps or fridges or cappucino machines getting processors and communication methods. Welcome to millenium 2.
