There's no denying that Microsoft is releasing numerous updates to improve the performance of the Windows 10 PC. But many consumers frequently criticize Windows 10 for its sluggish performance. When you first installed Windows or took it out of the box, you'll find that your computer was really quick. But suddenly, your computer starts working very slowly. Although the machine's lag won't result in any serious problems, it will make using Windows in general extremely unpleasant. 

The slow and sluggish Windows will undoubtedly waste a great deal of precious time and could even cost you money, especially when you use it for work. The operating system isn't always to blame for the lag and slowness. Your computer's slowness could be caused by a wide range of factors. The lag problem could be brought on by a lack of RAM, a virus or spyware consuming the resources you have, or simply a resource-intensive application running in the background. There are multiple reasons for this, but numerous fixes are also available. Let's find out:

Method 1: Turn off Unwanted Programs

If your system is running extremely slowly, getting rid of undesirable apps should be your first course of action. There are numerous applications that take some of your resources while running in the background. Your computer may experience significant lag from these programs, especially if there are a lot of them.

Remember that we're not discussing dangerous software that runs in the background, such as viruses. We're referring to common applications that many customers utilize on a daily basis, such as OneDrive, Adobe Creative Cloud, and your antivirus software. Usually, these programs have a default configuration that causes them to launch when your computer turns on. This means that as soon as you log in to your computer, these will begin to run in the background. If you are not using many of these, you can quickly disable them.

1. To launch the task manager, hold down the CTRL, SHIFT, and ESC keys at the same time. 
2. Select the Startup tab.
3. Now consider the programs that are not required. There ought to be a number of them. Select the one that you rarely use, then click Disable. For each program you see in the list, repeat this procedure.

Method 2: Update Drivers

Problems with drivers, particularly those for graphics cards, may be the root of Windows 10's slow performance. You can try updating the drivers on your computer to see if that helps. 

1. Press the Windows and R keys.
2. Enter devmgmt.msc into the search box.
3. Double-click the group that contains the device for which you have the most recent drivers. Double-click Display Adaptors, for instance if you discovered the most recent drivers for your display device.
4. On your device, select Update Driver Software from the context menu.
5. Select the option Browse my computer for driver software.
6. Click on the option Browse and navigate to the location where you downloaded the driver. Click Open after selecting the driver.
7. Select Next and adhere to any further instructions displayed on the screen.

If this method of updating the drivers seems too challenging to use, you can also have the driver downloaded automatically. For updating and downloading drivers, a ton of apps are available. You can download a variety of Free Driver Updater programs and configure them to meet your needs. 

Once you have finished updating the drivers, the issue ought to be solved. If it is not, you can move on to the next approach.

Method 3: Change Pagefile Size

The root folder of your Windows drive houses the pagefile, a virtual memory file. This file will not be visible to you until you tell the system to display hidden files. When your system's RAM (Random Access Memory) is low, it will transfer some memory to pagefile.sys so that it can continue to function. The PC manages the file automatically. But if you want your PC to run faster, you can try changing the size.

1) To adjust Windows' appearance and performance, type "performance" into the desktop's search box and select "Adjust the appearance and performance of Windows" from the pop-up menu.

2) Open the Advanced tab, then select the Change... option.

3) Remove the checkmark from the box next to Automatically manage paging file size for all drives. Mark the Drive where Windows 10 is installed. Change the Initial Size and Maximum Size to the Recommended Size after selecting Custom Size. Click the Set button after that. 

4) Press the OK key.

5) To make the changes effective, restart your computer.

Method 4: Defragment Hard Drives

Defragmenting hard drives is the most typical solution to the problem of Windows 10 running slowly. If you are unsure how to defragment hard drives, take the following actions:

1) In the search box, enter "defragment," then select "Defragment and Optimize Drives."

2) Choose the drive you want to defragment under Status. Tap or click Analyze to see if the drive needs to be optimized.

3) Select Optimize.

These are some of the most effective methods that you can use to speed up your Windows PC.

Conclusion

Working on a device that is incredibly slow and jerky all the time is the worst situation. Hopefully, the aforementioned adjustments will enhance the performance of your Windows 10 PC and put an end to persistent delays and lags. After making the aforementioned adjustments, if you still do not notice a performance boost, your device might be equipped with subpar parts. As a result, you will need to upgrade your device if you want it to perform better.
