Improve Your PC Performance

Improve your PC performance

Is your PC performing like a snail?

Have you opened up applications like chrome and wondered why the program window takes ages to appear? This can be the result of many different scenarios that could be affecting windows performance. From not having enough free space in both storage space and ram to having errors in the Windows operating system. Here are a few things that can be done to optimize the performance of windows.

Safety First

The first thing is first. No matter what you are doing. Always. Always, create a backup of your machine. The most basic form of backup that all windows computers have is system restore. System restore backs up only the system files and not your personal files. This is done so that when you need to restore your pc back from a previous restore point, it does not affect personal files.


Storage Size

Chances are that the PC has been used for a long time and during that time it would have built up temporary files that are no longer needed. It is good to start to do maintenance and have the computer remove these temporary files. In order to do this, you can right click on the System drive with the windows icon and select properties. Under the general tab that the properties window opens to, select Disk Clean-up. When the disk clean-up windows appear select Clean up system files.

If you clean-up the system without selecting clean-up system files, the computer will clean up files that do not require administrator access. This can be the only option for some users if they do not have access to the administrator account. This will still be able to reach the majority of temporary files but if you do have access to the administrator account, the PC can also clean up Windows updates and previous Windows operating system files. (Note: selecting previous Windows installation may appear if you have recently upgraded windows. Do not remove this unless you are out of space. If you find issues with the new version of Windows, you will be able to restore back to the previous version using these files.)



Windows allows you to change the visual effects of the operating system. Usually, this is set to allow windows to choose what’s best for the computer. This means that it is by default set to be at best performance until windows notice performance degradation. This would usually activate when the machine is running out of ram to use and windows will in-turn change the visual effects and adjust for best performance. What you can do is adjust for best performance in Windows 10 as the look will not be drastically changed. With Windows 7, setting this will make the operating system look similar to Windows XP when making these changes. To get to these settings go to:


    • Click the start button and type control panel
    • Select system and security
    • Select system
    • Select advanced system settings
    • In the performance section select settings

Now you can select adjust for best performance to improve the Windows operating system response time. Then select apply and ok. If you find that there has been a visual change that you can’t live without or it is bothering you, just go through the checkboxes to find which setting will restore the visual functionality. For example, if the font is being unclear in windows 10, you can select Smooth edges of screen fonts to put the font back to normal.


Windows System File Checker

It is always best to check if Windows system files are fine and not corrupt. When you find that the system is slow or certain programs that are built into the operating system are not opening like event viewer, the first thing to do is a system file check. To run the system scan just open the command prompt, type in sfc /scannow and hit the enter key. When the scan is complete, if the system is fine it will state: Windows Resource Protection did not find any integrity violations. If the scan does find corrupt files, the system will try to repair it and output the status of the repair. After acknowledging the status of the scan, it is best to restart the machine.


Disk Defragmentation

When Windows stores data, it is usually placed randomly on the disk as a first come first server order. So when files are removed from the partition which was in-between data, the new files will fill the space and then fill the rest of the free space. This cycle will continue and in time, will make the files stored on the partition very random. If your computer uses a hard drive for the operating system then this will cause response times to slow down. To check if your disk/partition needs defragmentation, open Disk Defragment and click analyse. If you have fragmented files, select Defrag for the system to try and re-arrange the files for better response time. SSD will show the option optimise only because actually defragmentation of an SSD is bad for the device as it will force a huge amount of write on the flash chips shortening the lifespan drastically. Optimise will instead do a trim function on the SSD which writes binary 0 and 1 to clear out data that may be in the free space.


The Most Noticeable Change

Check the startup of windows and disable programs from running automatically. This will make sure you have more ram to begin with and help you have a responsive system. For Windows 7, click on the start button and type msconfig. Select System Configuration and select startup. With Windows 10 open task manager and select Start-up. Select the program that you no longer need to automatically run when the pc turns on and select disable.
