Method 1: Using the Deployment Image Servicing and Management (DISM) Tool
First, open an elevated Command Prompt by pressing , typing cmd , right-clicking Command Prompt , and selecting Run as administrator . Step A: Analyze the Component Store
Windows 10 is serviced continuously via Cumulative Updates. Every month, Microsoft rolls out security patches and feature updates. When your 64-bit system updates, the following happens:
On a 64-bit (x64) version of Windows 10, the WinSxS folder must house components for both 64-bit applications and 32-bit (x86) backward-compatible applications. This dual architecture requirement naturally increases the size and complexity of the folder.

On x64 systems, which are now the norm for modern computers, the SxSi folder plays an equally crucial role. The primary difference is that the x64 architecture allows for more memory address space, enabling more complex and demanding applications to run. However, this also means that there are more libraries and assemblies to manage. The SxSi folder on an x64 Windows 10 system contains both 32-bit (WoW64) and 64-bit versions of libraries, ensuring that both types of applications can run smoothly.

SxS (S-by-S) is a flash memory standard developed by Sony and SanDisk, widely used in professional XDCAM camcorders. To bridge these cards with a modern PC, specialized drivers are required.

Windows stores the actual system file in the WinSxS directory and creates a "hard link" pointer to it in other folders, like C:\Windows\System32 . Windows Explorer counts the file size in both locations, meaning the reported size of WinSxS is often double its actual physical footprint on your hard drive.
Note: This process runs in the background and removes components that are no longer needed by the OS. Share public link

Introduced to solve this issue, the Side-by-Side (SxS) assembly store allows multiple versions of the exact same DLL or system component to reside on the disk simultaneously.
By following these best practices and understanding the role of SxSi on your x64 Windows 10 system, you can optimize your system's performance and stability.
Transition to Windows 11 if your hardware permits to maintain a modern, secure, and fully native x64 operating platform. Your current (e.g., 22H2).
Manually deleting files directly from the C:\Windows\WinSxS folder will corrupt the operating system, prevent future updates from installing, and likely require a complete OS reinstallation. Use only the following native, approved methods to reclaim disk space. Method 1: DISM Component Cleanup (Recommended) When your 64-bit system updates, the following happens:
