Files in the user’s profile (except those in the AppData folder) are preserved, as are any folders<br />
created in the root of the system drive and on other partitions, as well as File History data. All userinstalled<br />
desktop programs and Windows Store apps are removed, and a list of removed programs is<br />
saved on the desktop.<br />
This option boots into Windows RE and gathers user accounts, settings, data, and Windows Store<br />
apps. It then uses the most recent system rollup that is at least 28 days old to create a new, clean instance<br />
of the following folders, including all subfolders:<br />
■ ■<br />
■ ■<br />
■ ■<br />
■ ■<br />

\Windows<br />
\ProgramData<br />
\Program Files<br />
\Program Files (x86)<br />
%UserProfile%\AppData<br />
The reset operation also preserves device drivers, following the same rules as for system files.<br />
Drivers are restored to the most recent version that has been on the PC for at least 28 days. Device<br />
applets that are installed separately from the driver package are not restored as part of the reset<br />
process.<br />
Preinstalled Windows apps are restored to their factory version and state, and will be updated<br />
automatically after the reset is complete. Any apps and settings created as part of the original OEM<br />
image are restored from the customization container for those changes.<br />
After a reboot, the saved settings, data files, and apps are applied to the new operating system. This<br />
process can take several minutes to complete.<br />
Using the Keep My Files option requires a significant amount of free disk space to function—at least<br />
4 GB plus as much as twice the space occupied by any provisioning packages located in C:\Recovery\<br />
Customizations.<br />
The Remove Everything option<br />
This option (called Reset Your PC in Windows 8.1) removes all apps and user data, including user accounts<br />
and personalization settings. Choose the Remove Everything option when you plan to sell or<br />
give away an existing PC or reassign it to a new employee.<br />
Because this process, by design, involves significant data loss, the user must click through multiple<br />
warning screens that clearly describe what’s about to happen. The reset process also includes<br />
an option to scrub data from the drive so that it cannot easily be recovered using disk utilities. As<br />
Figure 9-5 notes, the Remove Files And Clean The Drive option can add hours to the process. Note<br />
that this option, while thorough, is not certified to meet any government or industry standards for<br />
data removal.<br />
