    It is not necessary to edit the registry to turn off disk compression in Windows 7. In Computer, right-click on Local Disk (C:) drive and click on Properties. On the Properties dialog box you will see a check box that you can uncheck of disk compression is on. If it is not checked, then it is not on. Obviously, if it is unchecked, you can check it to turn it on, but it will use system resources, so you need to weigh whether you need power or space.

    Um no… the checkbox found via Properties on the hardrive is to compress the entire drive in one shot. If you check this off, it will compress the entire drive when you click OK.

    The above article shows how to disable compression entirely so it can’t be invoked at all.

    NtfsDisableCompression in Windows 7 64-bit Registry does not seem to work properly.

    Any better suggestion?

    My own windows-theme picture that are png-compressed, are strongly jpg-compressed like before and some of them looks like – well – trash.

    Open a command prompt using the right click “run as administrator”. Then run “fsutil behavior set disableCompression 1” and reboot. This will disable NTFS compression for all volumes. Existin compressed files will stay compressed and can still be read. You will not be able to enable compression on any new files.
