It is better to disable apps which you use on purpose and are not required at all the times such as Microsoft Teams, Skype, etc.

To disable those apps, simply right-click on the Taskbar and open the Task Manager.

Next, move to the Startup tab, you will see a list of applications that launch on startup. Right-click on the unused app and click disable.

Terminate Resource Eating Programs:

At times there are certain applications that start consuming most of your resources due to some internal issue e.g., memory leak.

Thus, we need to find these problematic apps and ‘end task’ them to keep our PC performance intact.

So, Task Manager is the place to look for,

Right-click on the Taskbar and open the Task Manager. The Task Manager will be showing you a list of apps that are currently being run.

Click More details, a more detailed list of resource utilization will appear covering all the crucial components such as CPU, Memory, Disk, Network, and GPU utilization.

The apps and background processes that are eating your resources will normally be at the top of the list. However, you should scroll down to see every app’s utilization measure and then kill apps from the Task Manager which are the culprit simply by right-clicking them and clicking end task.

Uninstall Useless Programs:

Another good practice to follow, with time we install different programs and now they do not fulfill our purpose, or we don’t use those programs now. So, if there is some program that is useless and is not needed in the future such programs should be uninstalled from the computer.

These unneeded programs can be a reason for your lazy computer because they must be consuming disk space and might be running in the background or launching on the startup.

So, it’s good to get rid of these programs here how:

Go to Control Panel by simply searching on the Search Bar,

Change the view of the Control Panel to the category than under Program’s tab Click on Uninstall a program.

Then locate a useless program and just right-click on it and select Uninstall. Done!

Defragmentation of Disk:

Note: if you are using the latest version of Windows or your PC runs on SSD storage then there is no need for defragmentation because the latest versions of Windows do defragmentation automatically in the background.

However, defragmentation is utilized to set data in one place. In contrast, fragmentation disperses the files and data, this formulates an issue where the computer has to take more time to find data.

Here defragmentation comes in as it optimizes the whole thing and improves throughput and calls for efficient use of the computer.

In order to perform defragmentation of your disk, Go to My Computer and right-click on the disk you want to defragment and click on Properties, and then move to Tools. Under ‘Optimize and defragment drive’ – Click Optimize.

Now a list showing the disks installed will appear. Select the desired drive and Click on Analyze option to determine the fragmentation percentage (if below 10%, no need for defragmentation). Click the Optimize option to start the defragmenting of the drive.

Disk & Storage Cleanup:

Another solution that can prove to be a great deal, Windows comes with its preinstalled Disk, Storage Cleanup tools.

By using these tools, you will be able to delete any temporary files, Thumbnails, Delivery Optimization Files, and perform Windows Update Cleanup.

To perform a Cleanup, Type ‘Storage settings’ in the Search Bar and open it.

Choose the Temporary Files option and check the files you want to delete and click Remove files.

Scan For Malware:

Malicious software or files could be another possibility for your PC to act laggy. By Malware, we mean a collective of viruses, worms, trojan, ransomware, and spyware. Malware is something that can make your computer vulnerable as well as can impact the performance par of PC.

So, we recommend you scan your PC using Antivirus software. We can use the preinstalled Windows Security tool for this purpose which can work effectively.

Go to Windows Security > Virus & Threat Protection and Run Full Scan.

Upgrade your RAM:

Another fix can be upgrading your PC’s components, specifically, adding new memory sticks can be a lifesaver.

Many programs use too much of your RAM resource (as we know Chrome can be a criminal) moreover when users are running several programs simultaneously, it can create an issue if you don’t have enough RAM and technically you will be running out of memory and can cause a sluggish PC.

Random Access Memory (RAM) is crucial, used by the computer at runtime. So running out of Memory is a big No-No!

Therefore, adding a few RAM sticks will keep things smooth and you will be able to multitask quickly.

Expand Storage, Switch to SSD:

A pro-tip here, replacing an HDD with SSD could be the best solution because SSDs are faster and reliable than conventional HDDs.

If your computer takes ages to boot, then surely you need to opt for an SSD. Hard Disk Drives (HDD) have masses of moving parts and can take a lifetime to ignite.

In contrast, A Solid-State Drive (SSD) has flash memory and has better read/write cycles and is way more reliable.

Another thing of great concern is if you are running low on storage.

Yes, if your drive is low on free space, it could be a reason for your computer slow speed.

Apparently, a computer running out of storage space is bound to run slower and has the provided audacity to freeze at times. So, expanding the storage is the right thing to do!

Adjust Graphics & Animations:

With the recent variants of Windows, the operating systems have evolved a great deal in Graphical Interface and Animations.

So, changing the Graphics and Animations preferences according to the capabilities of your computer can be problem-solving.

To do so, simply type ‘Performance Options‘ in the Search Bar, a pop-up will appear then simply choose your preferred preference and click OK.

Buy a New Computer:

Despite walking through all the above solutions and still, you did not find peace. There is a chance that your machine is outdated or is not compatible enough with the newer variants of Windows, not enough to handle today’s age software.

These days computers come in an affordable range, so we recommend you opt for a new mid-range device instead of sticking with the current one. You should really think about this because it will be a great fix to all the problems you are facing right now.
