Explanation:
Windows device drivers and operating system files have been digitally signed by Microsoft to ensure
their quality. A Microsoft digital signature is your assurance that a particular file has met a certain
level of testing, and that the file has not been altered or overwritten by another program’s
installation process. Depending on how your administrator has configured your computer, Windows

either ignores device drivers that are not digitally signed, displays a warning when it detects device
drivers that are not digitally signed (the default behavior), or prevents you from installing device
drivers without digital signatures. Windows includes the following features to ensure that your
device drivers and system files remain in their original, digitally-signed state: •Windows File
Protection •System File Checker •File Signature Verification Windows XP help. Not A: operating
system files are included. Not C: the setting can be changed in the GUI.
