How to clean the system disk in Windows without compromising system integrity

The system disk in Windows plays a key role in ensuring stable operation of the operating system. It contains important system files, programs, and data needed to start and function your computer. From time to time, the system drive can become filled with junk, temporary files, and other unnecessary data, which can lead to poor performance and free space. However, cleaning the system disk requires special attention so as not to compromise the integrity of the operating system. In this article, we will look at some methods to clean up the system disk in Windows without the risk of damaging the system.

1. Built-in Disk Cleanup tool

Windows provides a built-in tool called Disk Cleanup that helps you remove temporary files, cache, and other unnecessary data from your system drive. To run this tool, follow these steps:

Open Windows Explorer.

Select the system drive (usually "C:") and right-click.

From the context menu, select Properties.

In the disk properties window, click the "Disk Cleanup" button.

Wait for the analysis to complete and select the files you want to delete.

Click "OK" and confirm deleting the files.

This tool allows you to delete temporary files, recycle bin files and other unnecessary data without affecting important system files.

2. Use of third party programs

There are also third-party programs specifically designed to clean up the system drive in Windows. Some of them offer more advanced cleaning and optimization features than the built-in Windows tool. However, when choosing a program, make sure that it is reliable and has positive user reviews. In our store you can purchase the CCleaner program.

3. Removing unnecessary programs:

Go to Settings: Open the Start menu and select Settings (gear icon). Another way is to right-click on the Start icon and select Settings.

Select "Applications": In the "Options" window, find and select the "Applications" section.

Go to Apps & Features: In the left pane, select Apps & Features. This will open a list of installed programs on your computer.

Select a program to uninstall: Scroll through the list and find the program you want to uninstall. Click on it to highlight it and then click the "Delete" button.

Confirm removal: You may be prompted to confirm the removal of the program. Follow the onscreen instructions to complete the uninstall process.

Repeat the process for other programs: Repeat the same steps for each program you want to remove.

3.1 Manually removing unnecessary files:

Clear temporary files: Open Windows Explorer and navigate to your system drive (usually "C:"). In the "Windows" folder, find the "Temp" folder and delete all the files inside it. These are temporary files that are no longer needed.

Clear web browser temporary files: Many web browsers also save temporary files, cache and history. Clear this data by going to your browser settings and selecting the appropriate option.

Removing old and unnecessary files: Browse the contents of your system drive and find files and folders that are no longer needed. These could be outdated program installation files, temporary files, boot files, etc. Delete them to free up disk space.

Caution: When deleting files manually, be careful not to delete important system files. If you are not sure that a file can be deleted, it is better to first move it to the Trash, and then delete it from the Trash after checking the system.

Manual removal of unnecessary programs and files allows you to select specific items to remove and control the process of cleaning your system drive. However, be careful not to delete important files that may be necessary for your operating system to function properly.

4. Regular updates and anti-virus scanning

In addition to cleaning, regularly updating the operating system and antivirus scanning can also help keep the system drive in order. Updates fix bugs and vulnerabilities, and anti-virus scanning helps detect and remove malware and files.


Keeping your system drive clean and tidy is important for the Windows operating system to function optimally. However, when cleaning the system disk, you should be careful not to delete important system files, which may compromise the integrity of the system. Use the above methods wisely and regularly check the health of your system drive to keep it in optimal condition.
