Windows 10: How to install Windows 10 with minimalizing used disc space?

Hi All,
My question is, how can I install Windows 10, that it uses the less disc space, it can?
My problem is, that I have laptop with 64 GB SSD, and after upgrading (from windows 8.1) to Windows 10, the used space is more than 35 GB, so now I have a very little free disc space now.
Thanks!

:)

I do not have a disc to boot windows 10, i am trying to use a USB drive with the installation software and do not get any of those options when using that to attempt the install.

How do i get a disc with windows 10....

 

It would be best to use clean install for that. My 10 + some software take 15GB (no pagefile/hibernation).

 

If you go to an elevated command prompt, and type this command, what does it say:
Code: compact /compactos:query[/quote] Ideally it should say 'The system is in the compact state'

Edit: another thing you can do is use Disk Cleanup to delete the old version of Windows, but I'd perhaps take a backup before doing that, in case you want to get it back somehow.

 

The articles I've read suggest Windows 10 installs in a compressed mode (the replacement for WIMBoot) on disks that are 32GB or less, and this seems to be the case as it installed compressed on a 32GB tablet I have but not compressed on a 64GB one. If the command DavidY mentions does not indicate you are in a compact state you'll need to fool the installer into thinking your disk is smaller than it is. Presumably you could force this on a larger disk by partitioning - delete all existing partitions, then create two equal sized ones that fill the disk (~30GB each), then delete the first one and tell Windows 10 to install in the unpartitioned space. After installation you should be able to delete the second ~30GB partition and expand your main partition to fill the disk. I stress that I have not tested this however!

The compact command also appears to let you change the state without reinstalling, maybe?

 

What exactly is taking up the space? Try Start/Settings/System/Storage and click on your disk drive on the right and find out what is taking up the most space. You can continue to click on the displayed categories to drill down to what is taking up the most room. Could be old windows installation, system restore points, etc. Let us know what you find out so we can zero in on more specific guidance.

 

Remove the Windows Old file and you should be good.

 

Yes I think you can change the state with that command.

 

Run Disk Cleanup, and do the Clean up system files option. Be aware, once you delete the Windows .old, you can't use the Rollback option.

 

Here's an interesting read. I had never heard of the compact command before!

Looks like the command to actually change the state is:
compact /CompactOs:always

To turn it off:
compact /CompactOS:never

 

Thanks for the ideas!
Deleting windows.old directory saves me lot of spaces.
Now the used space is "only" 26,6 GB. It has some temporary files (1,5GB), Office(?) (600MB), Lenovo Photo Master (674 MB), so I could reduce it a little bit.

I have only one question left. Settings-System-Storage says that I have 26,6 GB used space and 57,8GB total space. Where is the missing 6,2 GB (to 64GB disc which I have)?

 

That's normal. Manufacturers have for a long time quoted the unformatted capacity (which is greater than the actual usable space) and/or stated one Gigabyte to be 1000 Megabytes rather than 1024 (and so on). On an SSD you may also have some space reserved for wear leveling I think.

 

Most SSD's have a certain percentage 5 to 10% of their capacity blocked (OP). This empty space is used by the internal system of the SSD to facilitate their internal cleaning process. Unfortunately they sell using the total capacity rather than the usable capacity. I suspect this is what you are seeing.

 

Some more math, following on what xtcrefugee and Snakeyes said:

The manufacturer's "64 GB" equates in Windows GB units, to 64,000,000,000 / 1,024 / 1,024 / 1,024 = 59.6 GB

You'll have a minor amount taken up in hidden partitions (more if there is a factory restore partition, say 5 - 20 GB). The 59.6 - 57.8 = 1.8 other GB is likely over provisioning allowance on your SSD, which would be about 3% in this case minus the small hidden partition amounts.

You may get a better accounting of your 59.6 "true" GB from the Disk Management console display.
