I've been seeing a lot of advice about "debloating" computers, especially removing Copilot and various other preinstalled programs. People often label software as bloatware without explaining what makes it unnecessary or harmful. I understand why someone might want to remove Copilot, but I'd like a clearer definition and some practical examples.
What qualifies as bloatware? Is it simply software I didn't install, or does it need to consume system resources, advertise services, require a subscription, or interfere with Windows? Are manufacturer utilities such as Lenovo Vantage, Dell tools, OneDrive, or trial antivirus programs safe to remove, or is it usually better to disable them instead?
I'm currently using Revo Uninstaller, but I've seen mixed opinions about it. Should I keep using it or switch to another tool, and what are the reasons for that recommendation?

Bloatware isn't limited to third-party apps. Some vendor or operating-system software mainly promotes subscriptions, duplicates built-in features, or pushes services you never requested. Still, "preinstalled" doesn't automatically mean "bad." Outlook, OneDrive, BitLocker, accessibility tools, and device utilities may be useful depending on how you use the computer. Treat the term as a personal judgment, not a technical classification, and make changes one at a time so it's easy to undo them if something stops working.
Bloatware is subjective, but it usually means software that came preinstalled, wasn't requested, and provides little value to you. Trial antivirus programs, subscription promotions, advertising utilities, and duplicate apps are common examples. If you actually use something, such as Copilot, OneDrive, or a manufacturer control panel, it isn't bloatware for your particular setup.
Before uninstalling anything, check whether it runs at startup and whether you need its features. Disabling startup apps through Task Manager is often safer than deleting software outright. Manufacturer utilities can control firmware updates, battery modes, hotkeys, or device settings, so don't assume every vendor-branded app is useless.
The safest approach is to remove only programs you recognize and don't need. Use Windows' own Apps settings first, and avoid deleting system files or relying on aggressive scripts that promise to remove everything. Windows and Linux both have dependencies, so removing something that appears unnecessary can break features or updates.
Revo Uninstaller can be useful for cleaning up leftover files after a normal uninstall, but it isn't required. Bulk Crap Uninstaller is another option. Whichever tool you use, create a restore point and review what it wants to remove rather than automatically deleting every registry entry.
A clean Windows installation from official installation media is one way to avoid most manufacturer trialware, but it also removes useful drivers and utilities. Afterward, install the drivers and vendor tools you actually need. For an existing installation, the practical test is simple: does the program use CPU, memory, disk space, notifications, or network access without providing a feature you want? If not, uninstall it; otherwise, leave it alone or disable its startup behavior.
Disabling OneDrive from startup is often enough if you don't use it. Removing it completely can create extra problems if Windows or another application expects it to be present, and updates may reinstall or change related components.
