6. In the power options dialog box, make sure the “Processor power management” setting is set to “100%.”

7. Disable any power-saving features or options that may limit performance.

8. Update your drivers regularly to ensure optimal performance. Use a reliable driver updater tool like Driver Easy to easily update drivers.

By optimizing power settings, you can significantly reduce lag and improve your PC’s performance.

Patience is the key when dealing with computer lag, especially in Windows 10.

Disable Startup Programs

  • Open Task Manager by pressing Ctrl+Shift+Esc
  • Click on the Startup tab at the top of the Task Manager window
  • Review the list of programs that are set to start automatically when your PC boots up
  • Right-click on the program(s) you want to disable and select Disable
    Review the list of programs that are set to start automatically when your PC boots up
Right-click on the program(s) you want to disable and select Disable

Use System Restore Point

To use System Restore Point, follow these steps:
1. Press the Windows key and search for “System Restore.”
2. Open the System Restore tool and click “Next.”
3. Select a restore point from a time when your PC was running smoothly.
4. Click “Next” and then “Finish” to start the restoration process.

Remember to create a restore point before making any changes to your system, so you can easily revert back if needed.

System Restore Point is just one solution for fixing lag issues. If the problem persists, consider updating your drivers using a reliable tool like Driver Easy or adjusting your power saver plans to optimize performance.

Computer lag in Windows 10 can be frustrating, but remember that technology has its limits.

import psutil
import time

def check_cpu_usage():
cpu_percent = psutil.cpu_percent(interval=1)
if cpu_percent > 80:
print("High CPU usage detected!")
print("CPU usage is normal.")

def check_memory_usage():
virtual_memory = psutil.virtual_memory()
if virtual_memory.percent > 80:
print("High memory usage detected!")
print("Memory usage is normal.")

def main():
while True:
time.sleep(5) # Check every 5 seconds

if __name__ == "__main__":

This code uses the `psutil` library, which provides an easy interface to retrieve system information, including CPU and memory usage. The `check_cpu_usage` function checks the CPU usage, and if it exceeds 80%, it prints a message indicating high CPU usage. Similarly, the `check_memory_usage` function checks the memory usage, and if it exceeds 80%, it prints a message indicating high memory usage.

The `main` function continuously calls these two functions every 5 seconds to monitor the system’s CPU and memory usage. You can modify this code or add additional functionality based on your specific requirements for analyzing computer lagging.

Utilize ReadyBoost for Disk Caching

To fix Windows 10 lagging and a slow PC, one effective solution is to utilize ReadyBoost for disk caching. ReadyBoost is a feature in Windows that allows you to use a USB flash drive or SD card as additional cache memory. This can significantly improve the performance of your computer, especially if you have limited RAM.

To utilize ReadyBoost, follow these steps:

1. Insert a USB flash drive or SD card into your computer.
2. Right-click on the drive in File Explorer and select “Properties.”
3. Go to the “ReadyBoost” tab and select “Use this device.”
4. Adjust the amount of space you want to allocate for disk caching using the slider.
5. Click “Apply” and then “OK” to save the settings.

By utilizing ReadyBoost, you can speed up your computer and reduce lagging issues. Remember to choose a USB flash drive or SD card with a fast read/write speed for optimal performance.

Turn off Windows Tips and Tricks

If you’re experiencing lag and slow performance on your Windows 10 PC, one of the potential culprits could be the Windows Tips and Tricks feature. To disable it and potentially improve your computer’s performance, follow these steps:

1. Press the Windows key + I to open the Settings app.
2. Go to System and click on Notifications & actions.
3. Scroll down and toggle off the “Get tips, tricks, and suggestions as you use Windows” option.

Disabling Windows Tips and Tricks can prevent unnecessary notifications and background processes, which may be contributing to your PC’s lagging issue. If you still experience lag after turning off this feature, consider updating your drivers, especially graphics card drivers, as outdated drivers can also cause performance problems.

Remember to restart your computer after making any changes to ensure that they take effect.

Disable OneDrive Syncing

If you’re experiencing lagging and slow performance on your Windows 10 PC, disabling OneDrive syncing can help improve your computer’s speed.

To disable OneDrive syncing, follow these steps:

1. Right-click on the OneDrive icon in the taskbar and select “Settings.”
2. In the “Settings” tab, uncheck the box that says “Start OneDrive automatically when I sign in to Windows.”
3. Click “OK” to save the changes.

Disabling OneDrive syncing can free up system resources and prevent it from running in the background, which may be causing the lagging issue.

Remember to regularly update your drivers as outdated or incompatible drivers can also contribute to lagging and slow performance. Visit your manufacturer’s website to download and install the latest drivers for your graphics card, sound card, and other hardware.

Access OneDrive Files on-Demand

If your Windows 10 PC is lagging and running slow, there are several ways to fix the problem. One possible cause of lag is outdated or incompatible drivers. To resolve this, update your drivers by following these steps:

1. Press the Windows key + X and select “Device Manager.”
2. Expand the relevant categories (e.g., Display adapters for graphics card driver issues).
3. Right-click the device and select “Update driver.”
4. Choose “Search automatically for updated driver software” and follow the on-screen instructions.

Another reason for computer lagging could be energy saver plans. To adjust your energy saver settings, do the following:

5. Update your drivers to ensure they are compatible with Windows 10. Open Device Manager by right-clicking the Start button and selecting it from the menu. Expand the categories and right-click on a device to update its driver.

6. Adjust your power settings to the “High performance” plan. Open the Start menu, type “power options” in the search bar, and select “Power & sleep settings.” Choose the “High performance” plan.

Clean Registry

To fix Windows 10 lagging and a slow PC, cleaning the registry can be a helpful solution. The registry is a database that stores important settings and configurations for your computer. Over time, it can become cluttered with unnecessary entries, leading to performance issues.

To clean the registry, follow these steps:

1. Press the Windows key + R to open the Run dialog box.
2. Type “regedit” and press Enter to open the Registry Editor.
3. Back up your registry by clicking on “File” and then selecting “Export.”
4. Choose a location to save the backup and give it a name.
5. Once the backup is complete, navigate to the following location: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run.
6. Delete any unnecessary entries that you don’t recognize or no longer need.
7. Repeat steps 5 and 6 for the following locations: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run.
8. Close the Registry Editor and restart your computer.

Cleaning the registry can help improve overall system performance and reduce lag. However, it’s important to be cautious when making changes to the registry, as deleting the wrong entries can cause issues. If you’re unsure, it’s recommended to seek assistance from a knowledgeable individual or professional.
