Change Windows user to an Administrator from Ubuntu

8,728

To get back administrator access - Boot from the Ubuntu disk and install "chntpw". Run it from the command line (as root I imagine) and you can reset the admin permissions and password. (See this guide)

    I had a single account on my Windows 10 laptop which I changed from an administrator to a standard account not knowing the consequences.

    I tried booting Ubuntu (16.04) from a flash drive. But when I'm renaming sethc.exe file I get a popup showing "Error renaming file operation not supported". Please help me out of it and become the administrator user of the system.

      Have you mounted the Windows drive in a mode that allows writing? By default most Linux boot drives will only mount the Windows partition in read-only mode.

      I realize the duplicate has you use WinRE instead of Ubuntu but just because you want to use Ubuntu doesn't mean it's the correct approach to solve your problem. Use a Windows installation ISO instead
