+ decrypted (as far as Diablo2002 loader) + other bits.
Creates a folder %windir%\$NtUninstallKB494$, which actually sym link (i. e. contains $SYMBOLIC_LINK attribute).
But I noticed a new behavior, it creates key for start with image path - \systemroot\4151568013:1914276872.exe.
Main $DATA-stream in file 4151568013 is empty, but 2-nd stream stores it driver.

Just a note: The name of $NtUninstallKB494$ changes (depending on system volume date and time). The second stream of the above mentioned service contains an EXE. When a process tries to open that stream, it it killed and its EXE is deleted.

I made ​​a mistake when wrote about driver, it's exe file and not the driver.
