WinSxS | What it is and how it works


Are you looking for a guide that explains in detail what it is WinSxS and how to delete its superfluous content? Very well, you have found the guide that is right for you! In this study we will give you all the necessary instructions, so you will have a clear and comprehensive picture on the subject.

WinSxS is a folder that has important features, as we will see in the next lines. However, it tends to reach too large dimensions as the years go by.

So take a few minutes of free time: we are sure that, once you have finished reading, you will know what you have to do and you will dispel any further doubts you have. But no more delays, let’s go!

WinSxS what is it

WinSxS what is it

Let’s start by answering a simple question: what is WinSxS? This is a folder used by Windows Update and the operating system to restore the functionality of a previous version of Windows. This way you can restore damaged files, add or remove Windows features, etc.

However, this folder – over time – reaches a disproportionate size. This is due to the fact that modified files, as well as old versions, are added to the program in question when installing new updates for Windows.

It is therefore to perform operations on the contents of the WinSxS folder to recover some space and generally do some cleaning of the system files. If, after performing the Windows updates, the operating system is stable and has not turned out to be a problem, you can remove WinSxS folder items which are simply no longer used with some commands.

Here are the steps to do:

  • type cmd in the Windows search box;
  • press the key combination CTRL + SHIFT + ENTER – the command prompt with administrator rights will open;
  • here write dism /Online /Cleanup-Image /AnalyzaComponentStore, so you can first check how much space the WinSxS folder occupies.

Now we just have to wait for the report.

WinSxS can be deleted

Yes then, WinSxS can be deleted. And at the bottom of the report you can read “Recommended component archive cleaning”: if the item “Yes” appears to the right of the sentence, it is Windows itself that is advising you to clean the folder, which has obviously become too large by now.

What do you need to do to remove WinSxS elements no longer used by Windows? It’s not a complex operation, since you simply have to type the following command: dism /online /Cleanup-Image /StartComponentCleanup.

This is the procedure that goes through the command prompt, but if you want to go another route, there is the possibility of using the “Disk Cleanup” tool, which can still be used on Windows 10 at the moment. To delete unused content of the folder, just type “Disk Cleanup” in the search box of the operating system, then choose the drive where Windows is installed, click on “Clean up system files” and finally tick “Cleanup Windows Update”.

At this point, all you have to do is confirm by clicking OK. The procedure can be said to be completed. Virtually identical functionality is available by accessing the Windows 10 Storage Sense: Just choose “Enable Memory Sense” from the OS search box. This tool will probably replace Disk Cleanup for future versions of Windows 10.

Great, now you should have a complete and clear overview regarding the folder WinSxS. We have nothing left to do but make an appointment for you next time, in the hope that our guide has been useful to you in practice. Soon! Read also: WA Web | What it is and how it works
