How to Wipe Windows for a Fresh Install?

To wipe Windows for a fresh install, use Reset This PC or bootable installation media to remove all files, apps, and settings from your main drive. This clean install erases old system problems and gives you a new start with Windows. Back up important files first, then reinstall updates, drivers, and software after setup.

This guide shows you exactly how to wipe Windows and start fresh. You’ll learn the best backup steps, different wiping methods, and how to set up your computer after the install.

Why Wipe Windows for a Fresh Install?

A fresh Windows install fixes most computer problems by removing everything and starting over. Windows professionals call this a “clean install” because it wipes the disk before setting up a new disk layout, and installing a fresh, new copy of the Windows operating system. Microsoft’s official support documentation confirms that clean installations are effective for resolving system problems when other troubleshooting methods fail.

Here are the main reasons to wipe Windows:

Fix slow computer performance
Remove viruses and malware completely
Get rid of bloatware programs
Solve startup and shutdown problems
Prepare computer for selling
Fix corrupted system files
Start fresh after hardware changes

What Gets Deleted During a Windows Wipe?

Everything on your main drive gets deleted during a fresh install. Remember, a clean install will erase everything from the drive that Windows is installed on.

The wipe removes:

All programs and apps
Personal files (photos, documents, music)
User settings and preferences
Browser bookmarks and passwords
Email accounts and messages
Game saves and progress
Custom wallpapers and themes

Important: Only the main system drive (usually C:) gets wiped. Other drives stay safe.

Before You Wipe Windows: Essential Backup Steps

Back Up Your Important Files

Create backups of all files you want to keep before wiping Windows. When reinstalling Windows, it is essential to back up personal data such as IDs, login passwords, settings, and accounting data files.

Files to backup:

Documents folder – Work files, PDFs, text documents
Pictures folder – Photos, screenshots, graphics
Videos folder – Movie files, recordings
Music folder – Songs, playlists, audio files
Desktop files – Important shortcuts and documents
Download folder – Recent downloads you need

Where to save backups:

External USB hard drive (recommended)
Cloud storage (OneDrive, Google Drive)
Network storage device
Second computer

Save Browser Data

Export bookmarks and passwords before wiping Windows. Most browsers store important login information.

Chrome backup steps:

Click three dots menu → Bookmarks → Bookmark Manager
Click three dots → Export bookmarks
Save file to backup location

Firefox backup steps:

Press Ctrl+Shift+O → Import and Backup
Click Export Bookmarks to HTML

Get Software Product Keys

Write down product keys for paid software before wiping. For commercial software you’ve purchased, such as Microsoft Office or Adobe Photoshop, you may be able to retrieve the product keys stored on your computer.

Software to check:

Microsoft Office
Adobe programs
Antivirus software
PC games
Design software

Download Drivers

Save network and graphics drivers to external storage. Windows installation media includes LAN and WiFi drivers that go with your device. However, just in case, save in advance your Wireless or Ethernet (wired) LAN driver.

Network adapter drivers
Graphics card drivers
Audio drivers
Motherboard chipset drivers
