Bulk Crap Uninstaller: The Complete Guide to Cleaner Windows PCs

How to Remove Bloatware Quickly Using Bulk Crap Uninstaller

Bloatware—preinstalled apps and trial software—can slow your PC, consume storage, and clutter menus. Bulk Crap Uninstaller (BCUninstaller) is a free, powerful tool that automates deep uninstalls, removes leftovers, and helps you reclaim space quickly. This guide gives a fast, safe workflow to remove bloatware using BCUninstaller.

Before you start

• Backup point: Create a System Restore point (Windows) or a full backup if you’re concerned about losing settings.
• Close apps: Save work and close running programs.
• Run as admin: Launch BCUninstaller with Administrator privileges for full removal capability.

Step 1 — Download and install BCUninstaller

1. Visit the official BCUninstaller site and download the latest stable release.
2. Run the installer (or use the portable zip) and extract/install to a folder you control.

Step 2 — Initial scan and list cleanup

1. Open BCUninstaller (Run as administrator).
2. Let it populate the installed programs list; this may take a minute.
3. Use the search box to filter known manufacturers or app names (e.g., vendor bloatware).
4. Sort by Install Date or Size to spot large or recent unwanted items quickly.

Step 3 — Select items safely

1. For common bloatware (trial antivirus, OEM utilities, manufacturer toolbars), tick the checkboxes.
2. Leave Microsoft system components and drivers unchecked unless you’re certain. Tip: Use the “Hide Microsoft Apps” option to avoid accidental removal.
3. When in doubt, keep one copy of each major utility (e.g., keep factory recovery software if you rely on it).

Step 4 — Uninstall with automated checks

1. Click “Uninstall” after selecting items.
2. Choose the recommended automatic mode so BCUninstaller runs each program’s uninstaller first.
3. Allow BCUninstaller to run uninstallers and accept prompts shown by each app’s uninstaller.
4. When uninstallers finish, BCUninstaller will scan for leftover files, folders, and registry entries.

Step 5 — Remove leftovers (safe cleanup)

1. Review discovered leftovers; BCUninstaller categorizes items by files, folders, and registry keys.
2. Keep the defaults for ease: accept safe leftovers removal.
3. If you see unknown registry keys, skip them unless you can verify they belong to the removed app.

Step 6 — Automated forced uninstall (for stubborn apps)

1. If an app resists standard removal, use the “Forced Uninstall” option.
2. BCUninstaller will run more aggressive cleanup and registry removal.
3. Use forced mode sparingly; reserve for apps that have no working uninstaller.

Step 7 — Post-cleanup checks

1. Reboot the PC to complete removal of locked files and services.
2. Open Settings → Apps (or Control Panel) to confirm removed items are gone.
3. Check startup entries (Task Manager → Startup) and browser extensions to ensure nothing unwanted remains.

Tips for speed and safety

• Batch small groups: Uninstall related bloatware in batches (5–10) to avoid many restart prompts and to catch any problematic removal quickly.
• Portable version: Use BCUninstaller portable on new machines to remove OEM bloat without installing another program.
• Export list: Use BCUninstaller’s export feature to create a list of removed apps for auditing or reinstallation later.
• Whitelist/Blacklist: Create a whitelist of essential apps and a blacklist for known bloatware to speed future cleanups.
• Run periodically: Clean newly installed systems immediately and repeat every few months.

When not to remove something

• Leave drivers, recovery tools (unless you have alternate recovery media), and system-signed Microsoft components.
• Avoid removing apps you don’t recognize unless they’re clearly OEM extras.

Quick checklist (one-minute summary)

• Backup → Run BCUninstaller as admin → Hide Microsoft apps → Select bloatware → Uninstall → Remove leftovers → Reboot.

Using BCUninstaller lets you remove multiple unwanted programs quickly and cleanly, restoring disk space and improving performance without manual registry hunting.
