A clean-slate reinstall for Windows 8
By Fred Langa
Windows
8's built-in, automated 'Remove everything and reinstall' option
provides a fast way to give systems a totally fresh start.
Used properly, it can
clear up even the worst types of software trouble and malware infections
— it can even help improve your privacy and data security.
Win8's
repairing, restoring, and rebuilding tools go beyond those found in
previous versions of Windows. For example, Win 8's built-in Refresh option lets you run a fast, no-reformat, nondestructive reinstall of the operating system.
The Refresh
option restores Win8's core system files to their original condition but
doesn't alter user accounts, passwords, or data. However, it might
remove or alter some of your installed programs. (For more on Refresh,
see the Aug. 15 Top Story, "A 'no-reformat reinstall' for Windows 8.")
When system problems are too much for the Refresh option, Win8 also offers a second option: Remove everything and reinstall Windows
— a highly automated, built-in tool that completely removes your
existing setup and reinstalls Win8 from scratch. It even includes a
data-overwriting option that's useful when you're recycling a PC.
(Although Windows 8 initially refers to this function as Remove everything and reinstall Windows, it's more succinctly called Reset — which I'll use from here on out — throughout the remove/reinstall process.)
Reset is primarily useful for two circumstances:
- Securing personal data when the system is out of your hands: Reset can substantially improve privacy when you sell a PC, give it away, send it in for repair, or otherwise place the system in the hands of others. Not only will it wipe out all your user accounts, data, passwords, and installed programs, selecting the optional disk-wiping function helps ensure that no easily recoverable data is left on the hard drive.
- Recovering a severely compromised or malfunctioning PC: When other recovery methods prove futile, Win8's Reset will eliminate all traces of the bad setup and give you a simplified and properly functioning Win8 system. You can then reinstall any additional software you need (being careful to not re-create the previous problem) and then restore your user data from File History or whatever other backup medium you used.
In the rest of
this article, I'll walk you through a basic Reset operation to show how
it works and what options you'll encounter. In future installments, I'll
cover the rest of what's new and different about Win8's enhanced
backup/recovery systems.
A few clicks give Win8 a completely new start
You'll find
Win8's Reset function on the operating system's PC Settings/General
page. To get there, open the Charms bar and click Settings (the gear icon). Select Change PC settings (at the bottom of the Settings bar) and then click the General heading. Scroll down to Remove everything and reinstall Windows (circled in yellow in Figure 1).
Figure 1. Win8's Remove everything and reinstall Windows function is found on the PC settings/General page.
A full Windows 8 reset is serious business; it'll begin by deleting everything
on your hard drive. Before starting the process, Win8 warns you of
what's in store, as shown in Figure 2. (Note that Win8 now refers to the
process as Reset.)
Figure 2. Before making any changes, Win8 states what the Reset operation will do.
When you click Next,
Win8 then looks in common locations for all system files it'll need for
a successful reinstall. Those files might be in a system image or
recovery partition; on an attached or network-accessible hard drive; or
on Win8 installation media such as a setup DVD, flash drive, .iso file, etc.
If Reset can't find all needed files, it pauses and requests that you insert recovery/installation media, as shown in Figure 3.
Figure 3. Some needed restoration files might be on other media.
Once it has
access to all needed files, the Reset operation examines the PC's
hardware configuration. If it finds more than one local drive, you'll
see the dialog box shown in Figure 4, which lets you determine whether
the pending remove/reinstall process is applied only to the main Windows
drive (typically C:) — or to all drives.
Figure 4. Reset lets you leave nonsystem hard drives untouched.
Clicking the Show me the list of drives that will be affected lets you verify that only the drives you want cleaned will be included in the Reset process.
Once you've
selected which drive(s) to include, you can choose how thoroughly Reset
should clean them. As shown in Figure 5, the two choices are:
- Just remove my files is an ordinary, quick, file-delete operation. Keep in mind that a simple file deletion typically doesn't actually remove the file from the hard drive.
- Fully clean the drive performs a data wipe — a full overwrite operation that fills the entire hard drive with zeros, making recovery of the original data very difficult. (Technical aside: According to an MSDN blog, the Fully clean the drive option is analogous to the old-school DOS command format.exe C:\ /P:0.)
Figure 5. Select Fully clean the drive to completely remove all personal information.
Use the Just remove my files option if you're going to immediately restore Windows for your personal use. Use the safer (but slower) Fully clean the drive option if you're sending your PC in for repair, selling it, giving it away, or otherwise handing it over to third parties.
When you've made
your disk-cleaning choice, Win8 is ready to start the actual process of
removing your current setup and installing a virgin Win8 configuration.
A final confirmation dialog box, shown in Figure 6, reminds you of what
will happen and nags you to make sure you have current backups before
you proceed.
Figure 6. Reset displays a final warning — and a chance to cancel the reinstall process.
Once you click
Reset, there's no further input or intervention required. Note that your
PC will reboot several times during the Reset process. If you're using a
Win8 setup DVD (or other bootable medium) to provide required system
files, the reboots might prompt you to Press any key to boot from CD or DVD. Ignore the prompts; during Reset, Win8 should boot only from the C: drive.
Throughout the
process, Reset's progress is displayed by a series of minimally
informative screens, like those shown in Figures 7 and 8.

Figure 8: Some of the progress-status screens offer no specific information at all, beyond vague reassurance that something's happening.
A complete Reset
operation can be quite fast, though the time required depends on all
the normal system variables: raw system speed, amount of installed RAM,
hard-drive and other storage-device speed, and other such variables.
On my test
system (64-bit, 8GB of RAM, 20GB hard drive), a complete Reset took
about 20 minutes with the simple file-deletion option selected — and
about 30 minutes using the data-wipe option.
Larger hard drives take longer to wipe, of course. For example, on a Lenovo support page,
the hardware maker estimates that a data wipe–enabled Reset operation
will take about seven hours on its 2TB systems — and 10 hours on 3TB
PCs.
Final step: Restarting Windows 8 from scratch
You'll know the
Reset process is complete when your PC launches the standard initial
setup screens for an unconfigured Windows 8 installation. That includes
dialog boxes for entering your product key (see Figure 9), accepting the
product-licensing terms, setting up and personalizing user accounts,
and so on.
Figure 9. Near the end of the Reset process, Win8 will ask you to re-enter your product key.
You can use the Skip
option (see Figure 9) to defer entering the product Key to a later
time. That can give you time to ensure the new installation is solid and
stable before going through the subsequent Windows Activation process.
With the initial Win8 setup done, your system will revert back to the default Start screen, as shown in Figure 10.

Don't forget the updates!
As you continue to set up and customize your new Win8 system, allow
Windows Update to download and install whatever patches and updates the
operating system requires. You can let this happen in the background,
but it might take days to complete. If you'd rather get updating over
with as soon as possible, run Windows Update (Control Panel/System and Security/Windows Update) manually. Click Check for updates to get all patches more or less at once.
From this point
onward, you can configure your newly reinstalled Windows 8 setup in any
way you wish. For some expert guidance, see Woody Leonhard's Dec 20,
2012, article, "Eight simple steps for setting up Windows 8," and his Nov. 1, 2012, Top Story, "Win8 boot guide: Your first hour with the new OS."
Enjoy your factory-fresh, squeaky-clean, like-new Win8 installation!
