I have a 2 year old Samsung Series 7 Chronos 700Z5C Notebook - it came with an 8GB SSD with ExpressCache (verison 1.0.94 which Samsung have never updated). When I upgraded to Windows 10, the upgrade did not carry ExpressCache forward - it was not installed in the upgraded system.
Attempts to run the installer failed, rejected by Windows 10.
Samsung support (UK) say "What we can advise you is that we are already aware of this and we'll make sure to provide an update using our website the soonest possible time." Samsung US have a note saying ExpressCache is not supported for Windows 10(!). Some other manufacturers have provided updates.
I removed the registry entry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\UpgradeCompatibility blocking the installation and then the original (Samsung-provided) ExpressCache 1.0.94 for earlier Windows releases installed fine, and works much as before as far as I can tell from the results of the eecmd -info command. At least nothing has obviously gone wrong yet. Your mileage may differ.
I've read some hints suggesting that there is some conflict between MS and Condusiv about compatibility/signing, but I don't know. You can hope for a new release from Samsung, but my experience of Samsung products means I don't hold out much hope - their software and its support seems of a fairly low quality.
