|Thanks for you help, I found my own solution through googling. |
I installed two softwares Access Manager for Windows and Trust-No-Exe.
I hid all the drives including C: drive and restricted access to all the drives except C: drive. Access was only given to CD drives and Removable drives for the User and disabled Search, run, cmd.exe, explorer.exe, taskmanager, msiexec.exe etc. for the user using Access Manager for Windows.
All exe files are disabled except the permitted ones using Trust-No-Exe, i.e., executables from folders Program Files and Windows are allowed all other exe files are disabled.
Now the User can access only user's Desktop, My Documents, and CD or USB drives and cannot execute an exe file other than the exe files which are permitted.
If there is any other better way than this, your help is most welcome.
