Is your Windows 10 PC slow or glitchy, needing a fresh start? Formatting can help but risks data loss if done wrong. This guide offers a safe, clear way to reformat Windows 10, with trusted backup methods and post-format tweaks. Avoid sketchy tools and pricey software. Use WPS Office as a free, lightweight alternative to keep your PC fast and productive.
Part 1: How to Format Windows 10 – Step-by-Step Process
Formatting Windows 10 is like hitting the reset button, but it’s not without risks. The safest way is using Microsoft’s Media Creation Tool, which downloads a legit Windows 10 ISO—Reddit’s r/Windows10 users warn against fake ISOs from shady sites that can sneak in malware. You’ve got two options: Reset this PC (Settings > Update & Security > Recovery) keeps some files but may leave bloat, while a full reformat wipes everything for a clean slate, risking all data if you skip backups. Before starting, check your boot mode (UEFI or Legacy) in System Information (msinfo32) and back up drivers with tools like Double Driver, as TenForums tutorials stress, to avoid post-format hardware woes. Here’s how to do it right.
Step-by-Step: Formatting Windows 10
Step 1: Download the Media Creation Tool from microsoft.com, run it, and select Create installation media (USB or ISO).
Step 2: Insert an 8GB+ USB, choose USB flash drive in the tool, and let it prepare a bootable drive (takes 10–30 minutes).
Step 3: Restart your PC, enter BIOS (F2, Del, or similar key at boot), set the USB as the first boot device, and save changes.
Step 4: Boot from the USB, select Custom: Install Windows only, delete the system partition (back up first!), and install Windows 10 on the unallocated space.
Step 5: Follow prompts to complete setup, then reinstall drivers from your backup or manufacturer’s website.
Safety Checks
UEFI Mode: Ensure BIOS matches your system’s boot mode (msinfo32 > System Summary > BIOS Mode) to avoid install errors.
Driver Backup: Use Double Driver to save drivers, as missing ones can break hardware functionality post-format.
Data Risk: Full reformat erases all data—back up first (see Part 2). Reset this PC may keep files but risks residual bloat.
I used the Media Creation Tool for a clean install, and my PC felt brand-new, but forgetting to back up drivers meant a frantic trip to Dell’s site.
Part 2: Backup Before Formatting Windows 10
Backing up is non-negotiable before a reformat Windows 10 to prevent data loss. Free tools like File History (built-in to Windows) or EaseUS Todo Backup are popular on Reddit for their simplicity—File History saves to external drives, while EaseUS offers full disk imaging. Cloud options like Google Drive (15GB free) or OneDrive (5GB free) work, but slow uploads and storage limits can frustrate. Verify backup integrity with checksum tools like MD5 & SHA, as TenForums suggests, to ensure files aren’t corrupted.
Step-by-Step: Backing Up Files
Step 1: Connect an external drive, go to Settings > Update & Security > Backup, and turn on File History to select folders (e.g., Documents, Pictures).
Step 2: Alternatively, download EaseUS Todo Backup Free, launch it, select File Backup, choose folders, and save to your external drive.
Step 3: For cloud, upload critical files to Google Drive or OneDrive via their web interfaces or desktop apps, ensuring you stay under free storage limits.
Step 4: Verify backup integrity with WinMD5—generate a checksum for your backup file and compare it after copying to confirm no corruption.
Step 5: Test restoring a few files to ensure the backup works before formatting.
Backup Tips
File History: Simple but lacks advanced compression; good for basic needs.
EaseUS: Faster, with incremental backups, but free version has limits.
Cloud Limits: Google Drive’s 15GB beats OneDrive’s 5GB, but large backups may need paid tiers.
File History was my go-to for quick backups, but EaseUS’s compression saved space on my external drive. Checking checksums gave me peace of mind.
Part 3: Optimize Windows 10 After Formatting
A fresh Windows 10 install needs lightweight software and tweaks to stay fast. Install Firefox for a lean browser, Malwarebytes for antivirus, and Snappy Driver Installer for driver updates, as recommended on XDA-Developers. Disable startup bloatware via Task Manager (Ctrl+Shift+Esc > Startup tab), and optimize SSDs by enabling Trim (search “Defragment and Optimize Drives”), per YouTube tutorials with 500k+ views. Reddit’s r/Windows10 cautions against heavy suites like Microsoft Office, which slow down fresh systems.
Step-by-Step: Optimizing Windows 10
Step 1: Install Firefox from mozilla.org, Malwarebytes from malwarebytes.com, and Snappy Driver Installer from snappy-driver-installer.org.
Step 2: Open Task Manager (Ctrl + Shift + Esc), go to Startup, and disable non-essential apps (e.g., Skype, Adobe) to speed up boot.
Step 3: For SSDs, open Defragment and Optimize Drives (search in Start), select your SSD, and ensure “Scheduled optimization” is enabled for Trim.
Step 4: Disable bloatware services (Win + R, type “msconfig,” go to Services, check “Hide all Microsoft services,” disable third-party ones like McAfee).
Step 5: Run Windows Update (Settings > Update & Security) to install latest patches, then test performance with apps like Firefox.
Optimization Tips
Lightweight Apps: Firefox uses ~500MB less RAM than Chrome; Malwarebytes skips real-time bloat.
SSD Trim: Essential for SSD longevity and speed; avoid defragging SSDs.
Bloatware: Reddit hates OEM junk like Dell’s tools—uninstall via Settings > Apps.
Ditching McAfee for Malwarebytes and disabling startup apps shaved minutes off my boot time. Snappy Driver Installer was a breeze for driver updates.
Part 4: Cost-Efficient Software Solutions After Reformatting
WPS Office is the ideal post-format office suite for how to format Windows 10, offering AI-driven features and a free tier that outshines Microsoft 365’s $6.99/month cost.

WPS’s built-in PDF tools and smart templates streamline tasks, and it handles DOCX, XLSX, and PPTX files flawlessly. After reformatting, I installed WPS on a 2018 Dell Inspiron, and it tackled heavy spreadsheets without lag, with AI templates speeding up my reports.
