Facing a sluggish PC or setting up a new device, you’re likely eager for a Windows 10 clean install but overwhelmed by contradictory online guides and the fear of losing data. The maze of technical terms and unclear steps can make wiping your system feel risky. You want a straightforward, secure method to restore your PC’s performance without the stress. This guide cuts through the confusion, offering simple, reliable steps tailored to your needs, whether you’re a beginner or a tech-savvy user. Let’s make your fresh start smooth and worry-free.
Part 1: Windows 10 Clean Install with "Reset This PC" Option
The Windows 10 clean install via the "Reset This PC" option is the simplest way to wipe and reinstall Windows using built-in tools. It’s perfect for users who want a fresh OS without external media, unlike more complex methods we’ll explore.
Steps:
Step 1: Back up personal files to an external drive or cloud.
Step 2: Go to Settings > Update & Security > Recovery.
Step 3: Click “Reset this PC” and select “Remove everything.”
Step 4: Choose “Cloud download” or “Local reinstall” for the OS.
Step 5: Follow prompts to reinstall Windows.
Step 6: Complete setup and reinstall drivers.
I used this on my old laptop when it was crawling. The process was a breeze—no USB needed, just a few clicks. Cloud download took longer due to my spotty Wi-Fi, but the local option was snappy. Compared to manual installs, this Windows 10 clean install method is a lifesaver for non-techies.
Part 2: Windows 10 Clean Install via USB Installation Media
Using a bootable USB with Microsoft’s Media Creation Tool for a Windows 10 clean install offers flexibility, especially for non-bootable systems or new SSDs. It’s a step up from Reset This PC but still manageable.
Steps:
Step 1: Back up all files to a safe location.
Step 2: Download the Media Creation Tool and create a bootable USB (8GB+).
Step 3: Boot from the USB, adjusting BIOS boot order if needed.
Step 4: Click “Install Now” and select “Custom: Install Windows only.”
Step 5: Delete old partitions and install on unallocated space.
Step 6: Set up Windows and install updates/drivers.
I did this for a friend’s PC that wouldn’t boot. Creating the USB was quick, but tweaking the BIOS felt tricky until I found the right key. The install was smooth, and the system felt brand-new. This Windows 10 clean install method beats third-party tools for reliability.
Part 3: Clean Install Windows 10 Using CD/DVD Media
A Windows 10 clean install via CD/DVD is a classic option for users without USB ports or those preferring physical media. It’s less common but works well for older PCs.
Steps:
Step 1: Back up important files to an external drive.
Step 2: Download the Windows 10 ISO from Microsoft’s site.
Step 3: Burn the ISO to a DVD using a tool like Rufus or Windows Disc Image Burner.
Step 4: Boot from the DVD, adjusting BIOS if necessary.
Step 5: Choose “Custom install” and delete existing partitions.
Step 6: Install Windows and complete setup.
I helped a client with an old desktop using this method. Burning the DVD was straightforward, but booting from it took some BIOS fiddling. The install was slower than USB but got the job done. This Windows 10 clean install is great for retro setups.
Part 4: Clean Install Windows 10 on SSD + HDD Setup
For performance buffs, a Windows 10 clean install on an SSD with an HDD for storage maximizes speed and capacity. It’s advanced but rewarding for dual-drive systems.
Steps:
Step 1: Back up data from both SSD and HDD.
Step 2: Create a bootable USB or DVD with Media Creation Tool.
Step 3: Optionally disconnect the HDD to avoid formatting errors.
Step 4: Boot from the installer and select “Custom install.”
Step 5: Delete SSD partitions and install Windows on it.
Step 6: Reconnect HDD and set it for storage.
I set this up on my gaming PC, and the speed boost was unreal. Disconnecting the HDD saved me from a formatting scare. It’s not beginner-friendly, but for a fresh OS installation, this method shines for power users.

Part 6: Integrate WPS Office After a Windows 10 Clean Install
After a Windows 10 clean install, you need a lightweight office suite to jump back into work. WPS Office, a free, 200MB suite with 500 million users and a 4.8 Trustpilot score, is my go-to over heavier options like Microsoft Office.
Why It’s Recommended:
Low Resource Use: Runs smoothly on fresh systems.
Microsoft Compatibility: Handles Word, Excel, PowerPoint files perfectly.
Core Tools: Includes Writer, Spreadsheets, and Presentation.
Cloud Sync: Enables collaboration and file backup.
Quick Setup: Installs fast, no bloat.
After a USB clean install, I installed WPS Office to draft a report. It was up and running in minutes, and the cloud sync let me share files with a colleague instantly. Compared to Google Docs, WPS feels snappier offline.
FAQs
1. Do I need to back up my data before a clean install?
Yes, you should back up all important data before a clean install of Windows. A clean install wipes the drive, erasing all files, programs, and settings. Use an external drive, cloud storage, or another backup method to save your documents, photos, and other critical data.
2. Is a product key required for reinstalling Windows 10?
A product key may be needed if installing a different Windows 10 edition (e.g., switching from Home to Pro) or on a new device without a prior digital license. If Windows 10 was previously activated on your device, the digital license is tied to your hardware and stored on Microsoft’s servers, allowing automatic activation for the same edition during reinstallation. Check purchase records or use a tool like ProduKey to retrieve your key before wiping the system.
3. What software should I install after Windows setup?
After a Windows 10 clean install, prioritize installing drivers (from your PC manufacturer’s website for graphics, Wi-Fi, etc.), Windows security updates (via Settings > Update & Security), and a reliable antivirus (e.g., Windows Defender or a third-party option). Next, add essential productivity software like WPS Office for its lightweight, Microsoft-compatible document, spreadsheet, and presentation tools. Finally, install a web browser (e.g., Chrome or Firefox) and cloud backup tools (e.g., OneDrive) to streamline workflows and secure data.
Summary
A Windows 10 clean install is the ultimate reset for sluggish PCs or new setups. Reset This PC is the easiest, no tools required. USB installs offer flexibility for most users, while DVD installs suit older systems. SSD+HDD setups maximize performance for advanced users. Each method delivers a fresh OS installation tailored to your needs. Post-install, WPS Office is a must-have—its free, lightweight design and Microsoft compatibility keep your new system fast and productive, making it the perfect companion for any Windows 10 clean install.
