What Is Bloatware? Definition, Causes, Types, Risks & How to Remove It

If your new device feels slow from day one, bloatware could be the hidden culprit. Here's what it is and how to remove it safely.

Bloatware, sometimes called crapware, is unwanted or unnecessary software that manufacturers or carriers load on your device before you buy it, often ones you didn’t ask for or rarely use. They include it for revenue, brand promotion, or perceived added value.

Here are the main types of bloatware:

1. Trialware: Free trial versions of antivirus, office suites, or other software that encourage you to purchase a full subscription once the trial expires.

2. Manufacturer/OEM apps: Pre-installed utilities from PC or phone manufacturers, many of which duplicate built-in system features.

3. Carrier apps: Mobile apps pre-installed by wireless carriers for account management, entertainment, or promotions that are often difficult to remove.

4. Adware: Programs that push ads or pop-ups, sometimes bundled without clear disclosure, can be more intrusive or borderline malicious.

No, bloatware itself isn't a virus or malware. However, outdated or unpatched pre-installed apps can create security vulnerabilities that cybercriminals may exploit. Some bloatware may also include adware or tracking features, increasing privacy risks and your device's attack surface.

As mentioned above, bloatware is not always harmful. However, unnecessary bloatware can consume storage space through unused apps and cache buildup, drain battery life by running background processes, and use RAM and CPU resources, slowing app launches, multitasking, and overall system responsiveness—especially on lower-spec devices.

Generally, optional third-party apps, trial software, manufacturer promotions, and apps you never use are usually safe to uninstall. However, avoid uninstalling apps related to your operating system, hardware drivers (Windows), security features, or core system services unless you are certain they are unnecessary.

Here are some practical ways to identify safe-to-remove bloatware:

• Check the app's name, publisher, or developer in your device settings before removing it.

• Googling "[app name] safe to remove" or "[app name] what does it do" if unfamiliar.

• A good rule of thumb is to disable first before moving to permanent removal.

• On Windows, create a System Restore point before removing multiple apps. On mobile devices, back up important data to avoid unexpected issues.

Windows: Go to Settings > Apps > Installed apps, select the unwanted program, and click Uninstall. While this method works, it often leaves behind leftover files, empty folders, and registry entries. For a faster and more complete cleanup, consider IObit Uninstaller. It lets you uninstall unwanted programs, Windows apps, browser extensions, and bundled software in one click, then automatically scans for and removes residual files to free up more storage space.
