Hello
I noticed that chntpw say Not Tested when installing chntpw.tcz
I have now tested on my windows 7 and windows 10
I got error on windows 10 because I could not mount it as write and I needed to log into windows and run cmd as admin then type chkdsk /F and reboot and then reboot into corepure64 and mount sudo ntfs-3g /dev/mmcblk0p4 /mnt/mmcblk0p4
then cd to /mnt/mmcblk0p4/Windows/System32/config and run chntpw -i SAM
This works PERFECT
