Windows 11 Optimization Guide (What Actually Made My PC Fast Again Without Reinstalling)

When I first installed Windows 11 (24H2), my system didn’t feel right.

Not broken… just slow.

  • Boot time was longer than expected
  • UI felt slightly laggy
  • Disk usage randomly spiking
  • Background activity even during gaming

At one point I seriously thought:

👉 “Should I just reinstall Windows?”

Instead, I tried something different.

I went step by step and cleaned everything properly.

After about an hour of real optimization:

👉 Boot time dropped from ~45 seconds to ~12 seconds
👉 Games loaded noticeably faster (around 20–30%)
👉 System felt smooth again

This is the exact process I still follow after every major Windows update.


🧹 Step 1: Disable Background Apps (Hidden Performance Drain)

Windows runs a lot of apps in the background that you never open.

To fix this:

  • Go to Settings → Apps → Installed Apps
  • Click the three dots → Advanced options
  • Set Background app permissions → Never

Apps I disabled safely:

  • Xbox apps
  • Feedback Hub
  • Maps
  • News

👉 These apps still work when opened manually, but stop draining resources in the background.



🚀 Step 2: Remove Bloatware (Fastest Cleanup Method)

On a fresh install, I found apps like:

  • Spotify
  • TikTok
  • Candy Crush

Not useful for performance.


Option 1 — Using Winget (Manual Method)

winget uninstall "Spotify"
winget uninstall "Cortana"
winget uninstall "Your Phone"

Option 2 — GUI Tool (Easier)

Use ThisIsWin11 (open-source tool)

  • Removes unwanted apps
  • Disables telemetry safely

⚠️ Don’t remove essential apps like:

  • Microsoft Store
  • Calculator

⚙️ Step 3: Reduce Visual Effects (Instant Snappiness)



Animations look nice, but they cost performance.

Go to:

System → About → Advanced system settings → Performance → Settings

Select:

👉 Adjust for best performance

Then re-enable only:

  • Show thumbnails
  • Smooth fonts

👉 This made UI feel instantly faster on my system.





🧠 Step 4: Disable Startup Programs (Huge Boot Improvement)

Startup apps can easily double boot time.

To fix:

  • Open Task Manager → Startup Apps
  • Disable apps like:
    • Discord
    • Steam
    • Teams

I personally keep:

  • Windows Security
  • Audio drivers
  • OneDrive

👉 This alone reduced my boot time significantly.





🔋 Step 5: Optimize Power Plan (Very Important)

By default, Windows uses Balanced mode.

For better performance:

  • Press Win + R → powercfg.cpl
  • Select:
    • High Performance
    • or Ultimate Performance

👉 On laptops:

  • Use Balanced on battery
  • High Performance when plugged in

🧰 Step 6: Manage Background Services (Advanced but Effective)

Some services run even when you don’t need them.

Open:

Win + R → services.msc

Set these to Manual/Disabled (if unused):

  • Fax
  • Print Spooler (if no printer)
  • Remote Registry
  • Xbox Services

⚠️ Do NOT disable:

  • Windows Update
  • Security Center
  • Audio Services

👉 This reduces unnecessary CPU usage over time.


🧩 Step 7: Enable Storage Sense (Automatic Cleanup)

Instead of manually cleaning files:

  • Go to Settings → System → Storage
  • Turn ON Storage Sense

Set it to clean:

  • Temporary files
  • Recycle bin

👉 This keeps your system clean without effort.


🎮 Step 8: Optimize for Gaming (Important for FPS Stability)

Two quick settings:

  • Game Mode → ON
  • Hardware-accelerated GPU scheduling (HAGS) → ON

These help:

  • Reduce background interruptions
  • Improve frame consistency

👉 Especially useful for mid-range GPUs.


🧼 Step 9: Update Drivers and BIOS (Stability Fix)

Outdated drivers can cause:

  • Stutters
  • Poor performance
  • Power issues

Update:

  • GPU drivers (Nvidia/AMD)
  • Chipset drivers
  • BIOS (from manufacturer site)

⚠️ Always backup before BIOS updates.


Step 10: Check for Malware or Resource Hogs

If your system still feels slow:

  • Run Windows Security → Full Scan
  • Open Task Manager → sort by CPU/Memory

👉 I once found RGB software using ~12% CPU constantly.

Small things like this matter.


📊 My Real Results (Before vs After)

AreaBeforeAfter
Boot time~45 sec~12 sec
UI responsivenessLaggySmooth
Disk usage spikesFrequentMinimal
Game load timeSlow~20–30% faster

⚠️ Common Mistakes to Avoid

From experience:

❌ Installing random “optimization tools”
❌ Disabling critical Windows services
❌ Copy-pasting registry tweaks blindly
❌ Trying everything at once

👉 Simple, controlled changes work best.


My Personal Optimization Checklist

After every major update, I do this:

  • Remove bloat apps
  • Disable startup apps
  • Reduce visual effects
  • Set correct power plan
  • Enable Game Mode + HAGS
  • Update drivers

Takes ~30–60 minutes. Worth it every time.


💡 Final Thoughts

Windows 11 isn’t slow by design.

It’s just:

👉 Overloaded with background activity by default

Once you clean it properly:

👉 It becomes fast, stable, and predictable again

No reinstall needed.


🚀 If You Don’t Want to Do This Manually

These steps work, but they take time to test and apply correctly.

If you want everything optimized properly without trial and error:

👉 consider working with a professional PC optimization expert
