    Windows 10 takes less disk space than 7?

    I installed Windows 10 and despite there being a 5 GB windows.old folder, the C: drive has about 10 GB free that it didn't before the installation (accounting for the installation files which otherwise would have made it 15 GB). What is Windows 10 doing so differently that saves all that space?

    Microsoft wrote a blog post about the reduced footprint last year, which should give you more info.

    You can have a read through it here:

    Thanks. I guess they cleaned up some other stuff as well.

    Windows 8.1, 10

    I upgraded a Windows 7 laptop the other day. Before the upgrade, windows 7 had a folder with all the installed updates since whenever it was installed, which took more than 10GB. This was deleted from Windows.old and Windows 10 took less space when installed. So overall I saved disk space.

    Going forward, because Windows 10 is doing a full OS install every 6 month or so with its update, it shouldn't build up the huge stack of updates which Windows 7 had.

    I noticed this as well. My 1TB HDD was nearly full so I moved my music collection to a portable HD freeing up 350GB leaving my HDD with ~650GB used. I then did a clean install of Win10 64B and MS Office to a new SSD and transferred all my documents and files to a new 2TB HDD. Interestingly I am only using a little less than 200GB for my docs and files. Win10 on SSD is considerably faster than Win7 was on HDD which makes me wonder is I didn't have a bunch of corrupted system files or something taking up all the space. Anti malware Bytes and SFC never reported issues in Win7. No clue?
