What is this folder - C:\Windows\winsxs?

What is this C:\Windows\winsxs folder?

It is more than 4 GB... !!!
I donno if I should delete or do it... because my disk space is weak now... a free 30 GB for Win7 and got only 2 GB disk...
and the folder above contained as backup and some weird names... etc.
Examples:
x86_microsoft-windows - naturallanguage6_31bf3856ad364e35_6.1.7600.16385_none_9db12a5d8c0f6a9e
x86_microsoft-windows-s chrecognizerenu.ale_31bf3856ad364e35_6.1.7600.16385_en - us_ce081cc30a31a65b

and a folder named backup with content.
x86_microsoft-windows-font-truetype - mingliub_31bf3856ad364e35_6.1.7600.16385_none_c8f7fdc19988b363_mingliub.ttc_b8743970

and so on...
Is it a temporary folder or something that downloads updates and records here, or it creates a backup?

If you remove winsxs your operating system (Windows 7) will no longer work. This article is also applicable to Windows 7:

  • What is the ldiag file in Windows 7? How can I stop Windows write files in this folder?

    Can someone tell me what is the ldiag file in Windows 7?

    Somehow, Windows creates files and writes to this file. It keeps then write files until the entire hard drive is full. In other words, there is no place to save a restore point and no place to open Outlook, etc.

    When this has happened in the past, I had to contact the Microsoft response service and a level 2 technician to erase files. They said, the problem has been "fixed", but he continues to be...

    Do you know what "program" in Windows write files to this folder? I think it's a kind of diagnostic file. I tried the search "help" and the community and have not found anything to answer.

    Well, I hope that he is an expert in the community who can advise me on this. Thank you in advance.

    Thank you for your kindness in answering this question. I worked with technician level 2 Microsoft Office of response on the issue.

    I see that the files are part of the Lenovo system. Somehow, the Lenovo system analysis - triggered by something unknown to me--and wrote a text of 25 to 30 Gigabyte file!  I've identified it as a program of Lenovo, the write file and the program triggered by some unknown parameter. Then, I took the step to stop this program, Lenovo to run and then remove the text files.

    The steps you suggested are 'typical' first response / suggestions that you could do in that first level. However, in this case that they had nothing to do with the real problem.

    I often do a disk cleanup. This program is not clean these text files of the diagnosis of Lenovo.

    I start the computer in safe mode to diagnose problems. Yet once, just for the record, being in safe mode has nothing to do with the question of the Lenovo running program.

    No, there is no error message other than a message about 'disk full '. I ran a small program to see the size of the folder and was able to quickly identify the issue of file ldiag containing two text files, each about 25 gigabytes.

    Once again, thank you for your suggestions, but they were just basic, 'typical' suggestions and really had nothing to do with this specific problem. However, you have correctly identified the ldiag as being a file of Lenovo. Once that technology Tier 2 response office and found out that we were able to "solve" the problem.

    I had the same problem and it has chewed all my disk space. I have a 64-bit Windows 10 - disk 250 gig. I deleted all these files except those with current date and released the 150 gig. Much better to delete these temporary files to risking a crash operating system running out of disk space.

    If he has problems with the update or the permissions then simpler is to download the full version and trash the version currently installed to do a clean install of the new version.

    Click Start, click computer.  Then click on your system (probably C:\) drive and when it opens, you should see a folder named Windows.  This is the folder I'm talking about.

    Is what program this?  I don't think I've seen a program that automatically and without offering alternatives downloads in C:\Windows\TEMP never - even in the days of DOS.  Are you sure that this program is safe and compatible with your system and the version of Vista?

  • What is the perpose of the winsxs folder

    What is the perpose of the winsxs folder

    The WinSxs is the central repository of records for Windows. All installed files are placed in the WinSxS folder, including updated files up-to-date. So, you will have a lot of different versions of each file, allowing you to roll back service packs and Windows updates to a previous state.

    The current version of a file is hardlinked to the appropriate place in the rest of the file system. A hard link is a file name. All files have at least one hard link. Windows system files (usually) have two links in hard, one in WinSxS and one in c:\windows\system32. The two names pointing to the same bytes on the disk.

    As the files have two names, they are counted twice by Solution Explorer, once once of WinSxS and System32.

    There are other uses for it as well. It allows several programs to use different versions of DLLs.

  • Windows Server 2008 SP1: The C:\Windows\winsxs folder consuming 15Gb (!) of disk space.

    It's really annoying because at the time of installation, we thought that 25 GB should be plenty for the drive that contains the operating system only! Now we ran out of disk space on C:! (The only software installed on top of Windows is SQLServer 2008...). We organize this server and it's VERY expensive to get the C drive extended by our provider. So I'm looking for a solution urgently... and I can't seem to find it.

    Three questions:

    1. is there a tool offered by microsoft to reduce the size of this folder?

    2. upgrade to Windows 2008 R2 reduces disk space on C:\Windows\winsxs. In this way we can (temporarily) expand the capacity, perform the upgrade and return to 25 GB.

    3 - is Windows 2008 R2 also having this winsxs 'feature '?

    Kind regards

  • Windows 8 regenerate damage problem/backup duplicate and what is this "Windows.old"?

    Greetings!

    Currently, I'm new with Windows 8 and more than 3 months, I noticed my laptop is more slower to start-I recently installed the Adobe Suite as my largest software, as well as other essentials if you're curious.

    So, I just tried the good old system restore to see if the unknown blunders can be cancelled. Unfortunately, without success, I decided to update the system.

    Unfortunately once more after refreshing, the registry has been cleaned, but my software is still present in the neighbouring internal disk drive. At the same time, disk space in the disk drive that contains the operating system seems to have been mysteriously consumed (to about 40 GB free to only 15 GB free)

    Do you have any explanation and the solution to this? I would be very grateful for a quick response.
    Thank you for your time.

    --------------------EDIT-------------------------
    So I found the duplication - there is a 'Windows.old' containing my old system to front. Haha, what a relief

    Now, my questions are, 1) is it possible to be able to use/activate this beyond the parameters of operating system (from windows.old) again? (2) is it safe to upload it like any other normal folder (windows.old)? (3) is it safe to just manually remove my software (because it is devoid of its registers) and reinstall them again? Or you guys can even have the best solution for this.

    Any answer would be welcome.
    Thank you in advance to those who have an overview on this :)

    Hello

    Here are answers to your questions:
    1 years. Laughing out loud
    2 years. Yes, if you want, you can delete the Windows.old folder using this method:
    3 years. Yes.
    Hope that answers your query, good luck :)
