    Can I do a clean install now and keep my license ?


    Just as the title says.
    (It's a 'preview' license)

    Have you first upgraded from a legitimate Windows 7 / 8 license? If so, you can. If not, you need to do that first before Microsoft's servers will recognize your PC as being authorized for Windows 10.

    You can Clean Install and when asked for Key - just choose Skip

    If you had an activated preview release 10240 - Your PC has already seen an activated Windows 10 Pro version

    However, the preview key resulted in a license that expired in Jan 2016. Not sure if that was a hard date or a date that was a certain length of time from the date of install.

    Running slmgr /xpr in an elevated command prompt will tell you the license expiration date - or permanently activated.

    Yes, my info is correct, if you have an activated Preview Release 10240. MS gave you the Activation of Windows 10.

    I think so too, but it does no harm to verify with slmgr /xpr

    I run Windows10 since February, and only did updates so far, but in that time I installed and uninstalled a lot of software, as my SSD is small and can't have them all, so I feel like I want to do a clean install. Now my question is how will I keep my activated license ?

    Open command prompt (admin) and use the "slmgr /xpr" as stated by NavyLCDR post below

    If your the Windows script shows the dialog saying your machine is permanently activated then you are good to go. It'll be similar to script shown by Kyhi below:

    [QUOTE=Kyhi;335070]Attachment 30589QUOTE]

    To do the clean install, just follow the instructions in the TenForums tutorial How to Clean Install Windows 10
    . Make sure you do exactly the same way as in the tutorial.

    Yeah, it says that my machine is permanently activated, but I still have another question. Is it safe to delete all volumes during installation (so that I have a clean drive) ?
    Or to clean the hard-drive with diskpart ?
