Hello,
ExpressCache was not designed to work for Windows 10 natively. Updating to Windows 10 sometime may cause issue with ReadyCache installation. In the event of encountering any issue using ExpressCache software in Win 10, you can request SanDisk support for a CleanUp tool that should clean Uninstall it. Re-installaing should get things going for you.
I hope that answers your query.
Thanks!!!
