Methods to Fix Slow Down of Windows 10 After Update

Whatever the cause of the slowdown of your Windows 10 computer, if you follow the methods listed in this guide to the end, you will not face the slow Windows 10 problem again.

1. Roll Back the Windows Update

If new updates have caused the slowdown of your Windows 10, then rolling back these updates should do the trick. Microsoft has a built-in method by which you can achieve this.

To uninstall the updates, go to Settings > Update & Security > Windows Update > View update history.

Next, click on Uninstall updates. There, you’ll see a list of all the installed updates. You can then uninstall the updates that you believe have caused the problem.

In this way, you can uninstall the updates that have slowed down your Windows 10.

2. Repair Corrupt or Damaged Files

Sometimes due to updates getting stuck in between due to a network or similar issue, your crucial Windows files might end up corrupted or damaged.

This can make your system act unpredictably. You can repair the damage through the System File Checker, a free tool developed by Microsoft that comes in handy for corruption issues such as this one. The tool works by scanning your entire PC and then repairing whatever issues it can.

To run the System File Checker, you have to use the command prompt. Follow the steps listed below to get started:

1. Go to the Start menu search bar, type in ‘command prompt’.

2. Run the Command prompt as an administrator.
3. In the Command prompt, type sfc /scannow and hit Enter.

After the scan is complete, reboot your system. If the Windows 10 update did cause any corruption problems, they will be resolved after following this method.

Run the DISM Command

If the SFC command fails to recover your files, use the Deployment Image Servicing and Management (DISM) command. This is another Windows diagnostic tool created by Microsoft, but a more powerful one than SFC.

The DSIM command works by repairing your Windows system image files. To run this command, open the Command prompt with the administrator privileges, as we did above. Run the DISM /Online /Cleanup-Image /CheckHealth command to check if the image is corrupted.

If there are no corruption issues, you can run a more advanced scan through the Dism /Online /Cleanup-Image /ScanHealth command:

Note that this process may take a while. If you find corruption issues through the above step, run the Dism /Online /Cleanup-Image /RestoreHealth command to download and replace the damaged files.

Restart your computer after the command gets executed; run the SFC command again to repair the errors.

3. Disable Background Apps

Another popular method to resolve a slow Windows 10 after an update is to disable all the unnecessary background apps.

As you know, Windows 10 comes with many pre-installed apps apart from the ones that you download. These apps will keep running in the background—even when you are not using them. They don’t need to, though, as a good percentage of these apps are not really required for the functioning of Windows 10.

And the downside of this is that the apps eat away your CPU resources (RAM, cycles, etc.), which otherwise would have been free, leaving your computer slower than usual.

It is, therefore, helpful to terminate the unnecessary apps, and see if doing so results in a performance boost. Here’s how you can do that:

1. Open the Windows Settings.
2. Then, click on Privacy > Background Apps.
3. Choose which apps can run in the background section, turn-off all the unimportant apps.

Reboot your computer, and this will result in a normal computer speed.

4. Perform a Clean Boot

A clean boot is performed by starting a computer with minimum drivers and start-up applications; this helps in identifying the new applications that are causing the problems in your system.

Here’s how you, too, can do a clean boot:

1. In the Start menu search bar, type in ‘msconfig,’ and select System Configuration App.

2. In the Services tab, select Hide all Microsoft Services, and then click on Disable All.

3. Under the Startup tab, click on Open Task Manager.

4. In the Startup section, select and disable all the apps listed here one by one. You can also right-click on the background process and select Disable from the menu.

5. Close the Task Manager.
6. On the Startup tab of System Configuration, click on OK.

After performing all the above steps, you’re good to get started with the clean boot. Simply reboot your PC and the clean boot will begin.

5. Run Windows System Restore

System Restore is a free tool that works by taking your Windows to point in time wherever worked fine. It is frequently called upon on during a bug or malfunction in your Windows and you need to revert to a state where everything was functioning. Here, the System Restore can be used to take your Windows settings to the state preceding the update.

Follow the steps below to get started:

1. In the Start menu search bar, type in ‘system restore,’ and select Create a restore point.

2. A System Properties dialog box will appear.
3. Select System Protection and click on System Restore.

   Note: If you cannot click on this button, then your system doesn’t have a restore point yet, and thus, you cannot restore it.

4. Click on the Next button.
5. Pick a restore point and click on Scan for affected programs to confirm the apps that will be removed.
6. Click on Next to get started with the restore.
7. Finally, click on Finish.

After the restoration is complete, your system will be restored to its initial condition at the time of the last backup.

Note: The last resort for the slow Windows 10 issue is to use the Windows Factory Reset and start from scratch. Be warned though, as this is a nuclear option that will take your computer to the original, fresh state when you bought it.
