Review the output. Windows will explicitly tell you if a component store cleanup is recommended.
On a 64-bit Windows 10 system, the WinSxS folder must serve two different worlds: the native 64-bit environment and the 32-bit compatibility environment (WoW64). To manage this, you will find subfolders with distinct architecture identifiers:
SxS is a core Windows technology designed to solve "DLL Hell"—a situation where installing a new program would overwrite a shared system file (DLL) and break other programs .

The WinSxS folder is the central component repository for the entire Windows operating system. It is not just a simple folder; it is the backbone of Windows' component-based servicing (CBS) model. When you install a driver, enable a Windows feature (like .NET Framework 3.5), or, most importantly, install a Windows Update, the new files are not simply dropped into System32 . Instead, the update is installed as a "component package" inside WinSxS .
Part 1: Demystifying the WinSxS (Side-by-Side) Folder on Windows 10 x64
: It prevents "DLL Hell" by storing different versions of the same file. For example, an app needing an older version of a C++ Redistributable can access it from the SxS store while another app uses the latest version. Review the output
When Microsoft releases a Cumulative Update for Windows 10 x64, the update payload interacts heavily with the SxS store.

If you have recently updated Windows 10 x64 and verified that the system is stable, you can permanently delete the older, superseded update baselines. Run Command Prompt as an Administrator and execute: Dism /Online /Cleanup-Image /StartComponentCleanup Use code with caution.

To safely clean up old, superseded versions of updates, type the following command and press Enter: Dism.exe /Online /Cleanup-Image /StartComponentCleanup Use code with caution. Method 2: Resetting the Base of Superseded Components
A specific error like "C:\Windows\SYSTEM32\sxs.dll is either not designed to run on Windows or it contains an error" points to a corruption in a core system file used by the SxS service.
