i think  i used “wintousb” to install win 7 on the CZ43 stick, and it is activated.  

but i tried upgrade to win 10 and it stops and exits immediately from the install.   same thing if i try fresh install instead of just upgrade.

the win 10 is to install from another USB stick in a separate port.  

i have not tried installing win 10 on it from a DVD.

Hello, 

i think you are a bit confused, since the Ultra fit is a sandisk product and transcend is another flash memory manufacturer. Also this issue is related to microsoft since the Windows 10 seems to be corrupted and cannot be loaded.
