Notes on encrypting the operating system files or program files

Encrypting File System (EFS) in conjunction with the Trusted Platform Module (TPM),
you may not be able to log onto Windows or operate the software applications properly.

folders.
Observe the following when using the EFS.
Do not change the following default settings under Files and Folders on the View
tab in the Folder Options window.
