Cleaning up your Windows 10 computer isn’t just about clearing some space; it can actually make the system run smoother and faster — especially if it’s been sluggish or booting up painfully slow. Over time, you collect unnecessary files, background programs, and worse, malware or junk applications that drag performance down. The goal here isn’t to do a full reinstall (although that’s an option if things are really messed up), but to give your setup a good tune-up. Think of it as a digital spring cleaning that gets your machine back into shape without the hassle of a complete reformat. After walking through these steps, expect faster startups, less lag, and overall snappier responsiveness. For people who are tired of waiting forever for things to load, this can be a game-changer.
How to Clean Up Computer to Run Faster Windows 10
Clean Up with a good old Disk Cleanup tool
This is kinda old-school but still effective. The reason it helps is because it removes unnecessary files—like old Windows update logs, temp files, and trash from previous installs—that pile up over time. You’ll want to open File Explorer, then head into This PC > Local Disk (C:) > Properties and click on Disk Cleanup. If you don’t see all the options, click on Clean up system files. It allows you to target more stuff, like Windows Update files or old restore points. After it scans, check the boxes for temporary files, Recycle Bin, and other junk, then hit OK. On some setups this fails the first time, then works after reboot — Windows just has to go through its motions.
Uninstall unused apps from Apps & Features
This is kind of obvious, but it’s easy to forget how many apps are just sitting there taking up space. Go to Settings > Apps > Apps & Features. Pick out software you haven’t used in months — or ever — and uninstall. It’s like decluttering your digital closet, but for programs. Just be cautious with anything essential (like Office, drivers, or security tools).Sometimes old games or trial software are the easiest to target. Removing these can free up gigabytes if you’ve got a lot of junk hanging around.
Disable unnecessary startup programs
This is a proven way to speed up boot times. When your system starts, some programs automatically launch in the background — Dropbox, Skype, annoying Zoom updates—whatever. In Windows 10, hit Ctrl + Shift + Esc to open Task Manager, then go to the Startup tab. Disable programs you don’t need immediately. This step is all about preventing bloat from loading during startup, so your PC actually gets to a usable state faster. Sometimes on one setup it worked wonders, on another, a few startup programs just keep creeping back in — Windows likes to be sneaky. So, keep checking after updates.
Run a virus/malware scan with Windows Defender or a trusted tool
If your PC’s feeling downright sluggish, malware might be to blame. It’s kind of weird, but malware and adware can slow down every process, cause lag, or even hijack your CPU. Windows Defender is built-in and decent enough for quick scans, but for deeper cleaning, tools like Malwarebytes are worth a shot. To run a scan, go to Settings > Privacy & Security > Windows Security > Virus & Threat Protection and hit Quick scan. For thorough cleanup, pick Full scan. After a clean, you’ll at least know your system isn’t secretly running crypto-miners or other malware hogging resources.
Update Windows and device drivers
Another weird thing here — outdated drivers or Windows itself can cause huge performance hiccups. Windows 10 usually prompts for updates, but sometimes you need to check manually. Open Settings > Update & Security > Windows Update and click Check for updates. Also, for critical device drivers—graphics, network, audio—open Device Manager, right-click a device, then choose Update driver. It’s kind of like giving your PC a boost with fresh software bits. Not sure why it works, but on some machines, this step alone made a difference. You might notice smoother browsing, gaming, or even better Wi-Fi stability.
After bouncing through these, your PC should feel a lot lighter and more responsive. Faster boot, snappier app launches, maybe even less fan noise. It’s not magic, but it works.
Tips for Cleaning Up Computer to Run Faster Windows 10
- Stay on top of Windows and software updates—don’t ignore those patches.
- Use cloud storage for big files or backups to free up local space.
- Consider tools like Winhance or CCleaner for deeper cleaning, but be careful and read the settings.
- Create a system restore point before making major changes—because Windows has to make it harder than necessary sometimes.
- Set reminders to do a cleanup every 3-6 months, depending on how often you download stuff or install software.
Frequently Asked Questions
How often should I clean up my computer?
If it feels sluggish, or after big updates or installs, that’s a good time. Every three to six months is usually enough unless you’re a heavy downloader or gamer.
Why is my computer still slow after cleanup?
Could be hardware limitations, like an aging HDD or low RAM, or maybe malicious software. Sometimes a hardware upgrade is the only fix if cleanup doesn’t do the trick.
Can cleanup delete important files?
As long as you double-check what Disk Cleanup is targeting, it shouldn’t. Mainly, it deletes temp files, cache, and system logs. Still, always good to make a backup if you’re unsure.
Is it safe to disable all startup programs?
Not really, some are essential — like your antivirus or graphics driver. Just disable the ones you recognize and don’t need right away. Sometimes, Windows resets default startup items after an update anyway.
What’s a good malware scanner besides Windows Defender?
Malwarebytes is popular for good reason, and it’s free for on-demand scans. Having a second opinion helps spot things Defender might miss.

Wrap-up
Doing this stuff regularly keeps Windows 10 feeling fresh and fast, not to mention more secure. It’s kind of annoying and takes a little time, but the payoff — smoother operation, fewer frustrations — makes it worth the effort. If one thing doesn’t work, don’t get discouraged — sometimes it’s just trial and error, or a hardware upgrade might be needed. But hey, at least you’re taking control of your machine and keeping it healthy. Fingers crossed this helps someone save a few hours of headache.
