How to Speed Up Windows 11: 12 Tweaks That Actually Work

There’s a specific kind of frustration that hits when your Windows 11 machine starts lagging on tasks it handled effortlessly six months ago. Nothing dramatic happened — no virus, no major update gone wrong — it just got slow. I’ve been there more times than I’d like to admit, and after years of testing tweaks on my own machines, here’s what actually moves the needle.

Kill What’s Running in the Background

1. Disable startup programs. Open Task Manager (Ctrl+Shift+Esc), go to Startup Apps, and disable anything you don’t need at login. Spotify, Discord, Teams, OneDrive — they all add up. On a mid-range laptop I’ve shaved 20+ seconds off boot time just doing this.

2. Turn off background app permissions. Settings → Apps → Installed Apps, click any app and check whether it runs in the background. Most apps don’t need it.

3. Audit your system tray. Sort Task Manager by CPU or Memory. Anything sitting at 1–5% CPU while you’re not using it is a candidate for removal or restriction.

Windows Settings That Are Secretly Slow

4. Switch your power plan. Control Panel → Power Options → High Performance. If you’re wondering why your plugged-in laptop feels sluggish under load, this is often the culprit. Embarrassingly simple and embarrassingly effective.

5. Disable visual effects. Search «Adjust the appearance and performance of Windows» and select «Adjust for best performance.» You won’t miss the shadows under windows. You will notice everything feeling snappier.

6. Turn off transparency effects. Settings → Personalization → Colors → toggle off Transparency Effects. Frees up GPU resources, especially on integrated graphics machines.

7. Disable Search indexing. Right-click your C: drive → Properties → uncheck «Allow files to have contents indexed.» Cuts a surprising amount of background disk activity, especially on HDDs.

Storage and Memory Fixes

8. Enable Storage Sense. Settings → System → Storage → turn on Storage Sense. It automatically clears temp files and Windows Update remnants that can balloon to several gigabytes. I freed up 18GB on a client’s machine just with this.

9. Check your drive health. Run wmic diskdrive get status in admin Command Prompt. A degraded or failing drive makes everything feel slow — no software tweak fixes that. CrystalDiskInfo gives a deeper view.

10. Adjust virtual memory if RAM is tight. If you have 8GB or less, set a custom page file: 1.5x your RAM as initial size, 3x as maximum. Search «Adjust appearance and performance» → Advanced → Virtual Memory → Change.

Network and Updates

11. Limit Delivery Optimization bandwidth. Windows shares your connection to distribute updates to other PCs by default. Settings → Windows Update → Advanced Options → Delivery Optimization → Advanced Options, then cap the upload bandwidth. Makes a real difference on slower connections.

12. Restart properly — not just «shutdown.» Windows 11’s fast startup is a hibernate-style save state, not a real shutdown. A full restart clears cached processes and memory leaks. Weekly restarts keep things baseline-fresh. If your machine runs for weeks without one, that’s often why it feels progressively worse.

What to Expect

The startup program audit, visual effects toggle, and power plan switch are the three I always do first. They’re free, reversible, and they work every time. Don’t try all twelve at once — make changes in small batches, restart, and notice what actually shifted. That’s how you build intuition for what your specific machine needs.

A Few More Tweaks That Actually Matter

Beyond the basics, there are a few changes that consistently move the needle on machines that have been running for a year or more.

Disable Search Indexing on SSDs. Windows Search continuously indexes your drive to make file searches faster. On an HDD, this is worth it. On an SSD — which is already fast enough that raw search works fine — it’s just unnecessary background write activity. Right-click your C: drive in Explorer, go to Properties, and uncheck “Allow files on this drive to have contents indexed.” Apply to all subfolders. It’ll take a few minutes to process.

Check Your Power Plan. Go to Settings → System → Power & Sleep → Additional power settings. If you’re on a desktop and sitting on “Balanced,” switch to “High performance.” Balanced throttles the CPU when it thinks you don’t need full speed — which it sometimes misjudges during loading screens and app launches. High performance keeps the clock speed more consistent.

Clean Up the Context Menu. Right-click the desktop and count how many items appear. Every third-party app that adds itself there slows down the right-click response. A free tool called ShellExView (from NirSoft) lets you disable the ones you don’t need. It’s one of those changes that makes the system feel noticeably snappier in day-to-day use.

Measuring Before and After

If you want to actually track improvement rather than just feel it, use Task Manager’s Performance tab as your baseline. Note your CPU usage at idle, RAM committed, and disk activity. After applying changes, check again under the same conditions. A clean idle should sit below 5% CPU and under 60% RAM committed on a typical machine.

Boot time is the easiest metric: Windows records it. Open Event Viewer, go to Windows Logs → System, and filter for Event ID 100 — it shows the exact boot duration in milliseconds for every startup. Compare before and after your changes.
