If your computer feels sluggish, you don’t need a new machine or a weekend-long project to fix it. In most cases, slowdowns come from a handful of common culprits: too many apps launching at startup, bloated storage, outdated drivers, or power settings that prioritize battery life over performance. The good news is you can often improve PC speed in about 15 minutes with a few targeted tweaks—no special tools required. Below are nine proven changes that deliver quick, noticeable results, whether you’re on Windows 10 or Windows 11. Pick the ones that match your situation, follow the steps, and you’ll likely feel the difference immediately in boot time, app launches, and overall responsiveness.
Start with quick wins for PC speed (5 minutes)
1) Disable startup apps you don’t need
Every app that launches automatically competes for CPU, memory, and disk access. The result is a longer boot time and a system that feels “heavy” even after you log in.
Do this on Windows 10/11:
1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click Startup apps (Windows 11) or Startup tab (Windows 10).
3. Sort by Startup impact.
4. Right-click items you don’t need and choose Disable.
Common safe-to-disable examples (for most users):
– Spotify, Discord, Steam, Epic Games Launcher
– Adobe Creative Cloud helper apps (if you don’t need them immediately)
– Printer “quick launch” tools (you can still print without them)
– Updaters that aren’t security-critical
Keep enabled:
– Security software (Microsoft Defender is fine)
– Touchpad/keyboard utilities (if disabling breaks special keys)
– Audio drivers/enhancers you rely on
Tip: If you’re unsure, disable one or two at a time. You can always re-enable later.
2) Restart properly (don’t just shut down)
Many PCs aren’t truly “fresh-starting” when you shut down due to Fast Startup. A restart clears more temporary state, resets memory pressure, and can instantly fix runaway background processes that tank performance.
Quick action:
– Click Start → Power → Restart
If your system has been on for days, this alone can noticeably improve PC speed—especially when apps feel slow or browsers start lagging.
Reduce background load and cleanup what’s dragging you down (5–7 minutes)
3) Uninstall unused programs (and toolbars)
Old software often leaves background services, update schedulers, and helper tasks running even when you don’t use the app. Removing these reduces clutter and frees resources.
Do this:
1. Settings → Apps → Installed apps (Windows 11) or Apps & features (Windows 10)
2. Sort by Size or Installed date
3. Remove what you don’t use
Look for:
– Trial antivirus suites (running alongside Defender can cause slowdowns)
– “PC optimizer” tools (many are redundant and can add bloat)
– Old game launchers you no longer use
– Duplicate PDF readers and media players
Quick rule: If you haven’t opened it in 3–6 months and it’s not essential, uninstall it.
4) Run Storage Sense or Disk Cleanup to free space
When your main drive is nearly full, Windows has less room for temporary files, updates, and caching. That can slow everything down, particularly on older HDDs.
Target: Keep at least 15–20% free space on your system drive.
Windows 11/10 (Storage Sense):
1. Settings → System → Storage
2. Enable Storage Sense
3. Click Temporary files
4. Select safe categories like:
– Temporary files
– Delivery Optimization Files
– Thumbnails (optional)
– Recycle Bin (only if you don’t need what’s inside)
Optional deeper cleanup (built-in):
– Search “Disk Cleanup” → run as administrator
– Select system drive → Clean up system files
– Consider removing: Windows Update Cleanup (can be large)
Note: Don’t delete Downloads unless you’ve reviewed it.
Optimize Windows settings that affect PC speed
5) Set the right power mode (especially on laptops)
Power settings directly change how aggressively your CPU boosts, how quickly it downclocks, and how Windows manages background activity. Many laptops default to “Balanced” or energy-saving modes that feel slow when you’re plugged in.
Windows 11:
1. Settings → System → Power & battery
2. Power mode → Best performance (when plugged in)
Windows 10:
1. Settings → System → Power & sleep → Additional power settings
2. Choose High performance (if available)
Practical approach:
– Use Best performance when plugged in for maximum responsiveness
– Switch back to Balanced on battery if you need longer runtime
This is one of the fastest, most reliable tweaks to improve PC speed for everyday tasks.
6) Reduce visual effects (keep it tasteful)
Animations and transparency can look nice, but they cost resources—especially on older integrated graphics or systems with limited RAM.
Do this:
1. Search “Adjust the appearance and performance of Windows”
2. In Performance Options, choose:
– Adjust for best performance (fastest), or
– Custom: disable animations but keep “Smooth edges of screen fonts”
Also consider:
– Settings → Accessibility → Visual effects
– Turn off Animation effects and Transparency effects
Result: Snappier window movement, faster menus, less “laggy” UI.
Fix common hidden bottlenecks (drivers, malware, browser)
7) Update Windows and key drivers (graphics + storage)
Outdated drivers can cause slow boot times, stutters, high CPU usage, and poor disk performance. You don’t need to hunt every driver—focus on the ones that matter most.
Start here:
– Settings → Windows Update → Check for updates
– Install optional updates carefully (especially drivers); prioritize:
– Graphics drivers (Intel/AMD/NVIDIA)
– Chipset/storage controller drivers (often improves stability and disk behavior)
If you have a dedicated GPU, getting drivers straight from the vendor can help:
– NVIDIA drivers: https://www.nvidia.com/Download/index.aspx
– AMD drivers: https://www.amd.com/en/support
– Intel drivers: https://www.intel.com/content/www/us/en/download-center/home.html
Tip: If your PC recently got slower after an update, check Update history and consider rolling back a problematic driver in Device Manager.
8) Run a quick malware scan (built-in is fine)
Malware and adware are classic causes of sudden slowdowns—high CPU, constant disk usage, and strange background activity. A fast scan is worth the time.
Do this with Microsoft Defender:
1. Open Windows Security
2. Virus & threat protection
3. Quick scan
If you suspect something serious:
– Run a Full scan overnight, or
– Use Microsoft Defender Offline scan (more thorough)
Signs this might be your issue:
– Fans constantly spinning at idle
– Browser redirects or unwanted extensions
– Random pop-ups, new toolbars, or unknown apps installed
A clean system is foundational to consistent PC speed.
Make apps feel faster: browser, storage, and a smart hardware check
9) Tune your browser and trim extensions
For many people, “my PC is slow” really means “my browser is slow.” Too many tabs and extensions can chew through RAM and CPU.
Fast browser tune-up checklist:
– Update the browser (Chrome/Edge/Firefox)
– Disable or remove extensions you don’t use
– Turn on sleeping tabs (Edge) or memory saver (Chrome)
– Clear cached files if pages load oddly or slowly
Edge (Sleeping tabs):
1. Settings → System and performance
2. Enable Sleeping tabs and set a short time (like 5–15 minutes)
Chrome (Memory Saver):
1. Settings → Performance
2. Turn on Memory Saver
Quick reality check: If you routinely keep 30–100 tabs open, adding RAM can help, but the settings above often deliver immediate gains in PC speed without spending anything.
Bonus: 60-second storage health check (SSD vs HDD)
This isn’t a “tweak,” but it explains a lot. If Windows is installed on a mechanical hard drive (HDD), no amount of software cleaning will match the responsiveness of an SSD.
Check your drive type:
1. Open Task Manager → Performance
2. Click Disk
3. Look for SSD or HDD
If it’s HDD:
– The single biggest upgrade for PC speed is moving Windows to an SSD
– Even a budget SATA SSD can drastically reduce boot and app load times
If it’s SSD:
– Make sure you still have free space (aim for 15–20%)
– Avoid aggressive “defrag” tools; Windows handles optimization automatically

15-minute plan: do this in order (no overthinking)
If you want the fastest path to results, follow this simple sequence:
1. Restart your PC
2. Disable high-impact startup apps
3. Uninstall 1–3 unused programs
4. Run Storage Sense/Temporary files cleanup
5. Set Power mode to Best performance (plugged in)
6. Reduce visual effects (disable animations)
7. Run Windows Update (and graphics driver update if needed)
8. Run a quick malware scan
9. Trim browser extensions and enable sleeping tabs/memory saver
This order is intentional: it targets the most common bottlenecks first, then moves to updates and deeper checks.
Wrap-up: get your PC speed back today
You don’t need a full reinstall to make your computer feel quick again. In about 15 minutes, you can improve PC speed by cutting startup bloat, freeing storage space, choosing performance-friendly power and visual settings, updating key drivers, scanning for malware, and trimming browser overhead. If your system is still sluggish after these tweaks—especially if you’re on an HDD—the next logical step is an SSD upgrade or a quick diagnostic to identify a failing drive or insufficient RAM.
