    Win10 upgrade or clean install?

    Is there any way to inspect a Win10 installation and be able to tell if a clean install (IOW, the HD was wiped clean prior to the install) was done, or if the current installation was the result of the free upgrade only?
    Thanks in advance

    If it was an upgrade then in Windows C: you should see a Windows10Upgrade file folder.

    However, if it was originally an upgrade and a clean install was done later, then that file may longer be there.

    Another tell-tale sign of a clean install would be in Programs and Features where all of the installed programs would have the same or near same installation date as after a clean install, all programs would need to be reinstalled.

    Law enforcement would use forensics software to examine the disk. If you want to know how it works, there is a free trial of such a program here:-

    If it's a brand machine, look for all the crapware the manufacturer typically installs. If it's there, only an upgrade was done.
