The same way you uninstall any other Windows application: in the list of apps in the Settings app.

i just uninstalled, Ldntvdm.dll is still present and open in winlogon.exe, how to remove?

Remove ldntvdm.dll entry from Key AppInit_DLLs in the following 2 locations:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Windows

ALT+ENTER Fullscreen doesn't work anymore since Windows 7. This is due to the change of the display driver model from XPDM to WDDM, which doesn't support 1:1 IO pass-through anymore. On Windows 7 32bit, this can be fixed with a few tricks, but starting with Windows 8, XPDM support was eliminated from the kernel and thus, it's technically impossible. So you have to stick with Windows XP or Windows 7 32bit for true Fullscreen support. NB: Fullscreen support never worked on 64bit Windows versions, because IO-Bitmap cannot be modified on 64bit Windows versions. I'm note aware of CTRL+A, c, v working on cmd, as keys get passed to the running application (which is correct behaviour)
