How to view the actual size of the Win8.1 WinSxS folder

When it comes to Win7/Win8.1 redundancy, I have to mention this WinSxS special folder. This folder is located in the C:Windows directory path, which stores a large number of system system backups and update patch backups. Over time, WinSxS has also become the largest folder for system disks.
For ordinary users, the most concern is why the WinSxS folder continues to grow bigger? In fact, the specific function of the WinSxS folder is component storage, which stores important Windows component functions, such as the familiar C:Windowssystem32 directory.
The WinSxS folder itself and the C:Windowssystem32 directory create a hard link, so it is difficult to directly view the actual size in the resource manager, refer to the following figure:

Then how do we view this folder actually At this time, we directly use the built-in DISM management tool of Win7 and Win8.1 to query the folder size. The specific operation is as follows: ——
1. For example, Win8.1 platform, we right click the start button. Select Command Prompt (Administrator); Win7 platform click Start menu, enter cmd in the search box, then right click to run as administrator;

2, enter the following query command in the open command prompt :
Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore
//Query the actual size of the current WinSxS folder

It is not difficult to see from the above picture that the actual capacity of the WinSxS folder is lower than Windows resources. The manager's data is displayed.
In the WinSxS folder, it consists of three main parts: 1. Shared with Windows; 2. Backup and disabled functions; 3. Cache and temporary data.
