clean up the WinSxS folder

Even though Windows is the best and most popular desktop operating system, it still has many flaws. Windows is less optimized than macOS, which results in more storage and resource consumption.

The one problem that Windows users often face is insufficient storage space. While there are many ways to free up storage space on Windows like you can uninstall programs, delete photos & videos, etc., what if you don’t want to remove any personal files and still wants to expand the storage?

In such a case, you must clean up the WinSxS folder on your Windows computer. This article will discuss WinSxS in detail and how you can clean up this folder. Let’s get started.

What is the WinSxS folder in Windows?

Well, WinSxS (Windows Side by Side) is a folder that resides on your system installation drive. It is where Windows stores its recovery files, files needed to install updates, previous versions of Windows components, and more.

It’s a very important folder and helps you revert to the previous state in case of software failure. Since Windows often use this WinSxS to store new files, the folder size can expand over time, leading to the low disk space problem.

The folder is located in your system installation drive. For example, if C: Drive is your system installation drive, you will find the WinSxS folder in the C:\Windows\WinSxS path.

When you open this folder, you will notice that the files are stored in more than one place in the operating system. However, there’s only one copy of a file, and the rest of the files are just hard links.
