  • What is WinSxS?

    My ISA Servers are complaing of a lack of space on the system drive. I've found a folder called WinSxS and was wondering what does it do and is it OK to delete?

    Win2K3. Thanks.

      Sxs stands for side by side versioning. This was a feature first
      introduced in Windows ME and improved in XP. It was Microsoft's solution to the "DLL Hell" issue that plagued Win 9x and provided a way to support multiple versions of same named DLLs. Windows would recognize a potential conflict and place an incoming DLL in the Winsxs tree rather than overwriting it elsewhere.

      So it's probably not advisable to delete or mess with it.

        Looks like that post is a rip off of this article:

        Sxs stands for side by side versioning. This was an feature first
        introduced
        , oddly enough, in Windows ME and of course improved in XP. It
        was Microsoft's solution to the "DLL Hell" issue that plagued Win 9x and
        provided a way to support multiple versions of same named DLLs. Windows
        would recognize a potential conflict and place an incoming DLL in the Winsxs
        tree rather than overwriting it elsewhere
        , would store applicable registry
        data, etc.
