Clean Windows 11 Install Guide: Remove Bloatware & Optimize

Preparation Phase

Before reinstalling Windows, proper preparation prevents critical issues. Based on hands-on experience, these steps are non-negotiable for a smooth process.

Creating Installation Media

Download the official Windows 11 ISO from Microsoft's site. When the download page denies access—a common occurrence—persist until successful. The ISO file averages 7GB. Use Microsoft's Media Creation Tool to properly transfer it to a USB drive. Never drag-drop ISO files directly—this creates unbootable media.

Driver Backup Strategy

Identify your motherboard model via System Information (press Win+R, type msinfo32). For laptops, search "[Your Laptop Model] + motherboard drivers." Download LAN (ethernet), Wi-Fi, and chipset drivers from the manufacturer's official site. Store them on another device or cloud storage since your primary PC will be wiped.

Application Settings Backup

Backup critical app configurations. For PowerToys: Open settings > Backup. For OBS Studio: File > Show Settings Folder. Transfer these backups externally. This preserves hours of customization work.

Installation Process

With preparations complete, proceed to installation.

BIOS Access Methods

Restart and repeatedly press Delete or F2. Alternatively, hold Shift while clicking Restart in Windows > Troubleshoot > UEFI Firmware Settings. Critical insight: If your USB doesn't appear in boot priority, access the Boot Menu (usually F8/F12) where hidden drives appear.

Partition Management

During installation:

Select "I don't have a product key" (activate later)
Delete all existing partitions when prompted
Select the largest unallocated space
Expert tip: New PCs may require driver loading via "Load Driver" if storage isn't detected.

Skipping Microsoft Account

Bypass the forced login:

Unplug internet cable
At network screen, press Shift+F10
Type OOBE\BYPASSNRO and press Enter
After reboot, select "I don't have internet" > "Continue with limited setup"
This leverages an official (but unadvertised) installation workflow.

Post-Install Optimization

A clean Windows is just the beginning. These optimizations remove residual bloat.

Essential System Tweaks

Disable mouse acceleration: Settings > Bluetooth & devices > Mouse > Additional settings > Pointer Options > Uncheck "Enhance pointer precision"
Maximize refresh rate: System > Display > Advanced display > Choose highest refresh rate
Remove animations: Search "Adjust appearance" > Uncheck "Animate windows" and "Fade or slide menus"

Debloating with Chris Titus Tool

Download the utility from chrisitus.com (official site). In Terminal (admin):

Recommended actions:

Apply "Standard" tweaks (removes telemetry, OneDrive)
Disable Bing search in Start Menu
Enable "Ultimate Performance" power plan
Remove Copilot and Widgets
Why this works: It automates registry edits and PowerShell commands that would take hours manually.

Manual Bloatware Removal

Uninstall preloaded apps: Settings > Apps > Installed apps > Remove Clipchamp, Feedback Hub, etc.
Disable widgets: Taskbar settings > Disable "Widgets"
Purge Web Experience Pack: Terminal (admin) > winget uninstall "Windows Web Experience Pack"
