Is your laptop running slow? Sometimes, the reason might not be malware or storage issues — it could be unnecessary background services hogging your system’s resources. One quick registry tweak can help improve performance, especially on lower-end machines.
⚠️ Warning: Editing the Windows Registry can affect your system if done incorrectly. Follow the steps carefully and only proceed if you’re comfortable with system-level changes.
Step-by-Step Guide to Speed Up Your Laptop
✅ Step 1: Open the Run Command
Press Windows + R on your keyboard to open the Run dialog box.
✅ Step 2: Type "regedit"
In the Run box, type: "regedit"
Then click OK or hit Enter.
✅ Step 3: Allow the Registry Editor
You’ll get a prompt from User Account Control (UAC) asking for permission to make changes. Click Yes to continue.
✅ Step 4: Navigate Through the Registry
Inside the Registry Editor, carefully follow this path: HKEY_LOCAL_MACHINE>>>SYSTEM>>>ControlSet001>>>Services>>>NDU
To do this:
-
Click on "
HKEY_LOCAL_MACHINE" -
Then click "
SYSTEM" -
Next, click "
ControlSet001" -
Expand "
Services" -
Scroll down and click on "
NDU"
✅ Step 5: Modify the NDU Service
Once you're in the NDU folder:
-
Find the item named Start on the right pane
-
Double-click on it
-
A box will pop up. Change the Value data from 2 to 4
-
Click OK
Changing this setting disables the Network Diagnostic Usage service, which can reduce unnecessary RAM usage.
🔁 Step 6: Restart Your Laptop
After making the change, restart your system to apply the new settings.
⚡ Why This Works
The NDU (Network Diagnostic Usage) service helps Windows track network data usage. However, on some systems — especially low-RAM laptops — it can consume more memory than necessary. Disabling it can improve performance and responsiveness.
🧠 Final Thoughts
This is just one tweak, but it can make a noticeable difference, especially if your laptop has limited resources. Remember, always create a backup or system restore point before making any changes to your registry.
