I have Windows vista ultimate sp1 64bit. I observe that "winsxs"  folder takes a big piece of my disk(11.2 Gb).Is it right to delete the contents of this folder  although the operating system does not permit such action.I suppose that i have the ability to delete them via my other operating system xp sp2 (32bit).

    Take a look at this very informative page:
    The Secret Of Windows Vista Winsxs Folder.

    And, to answer your question about deleting the folder, I'll quote from that page:

    As mentioned, Windows stores the old dll's and library components in the WinSxS folder. Now if a newer version of this file is a part of the OS, but a particular application requires a particular older version for running, then the older version from the winsxs folder will be used, leaving the newer version in its present place, for other applications which may require it.
    So obviously you cannot delete this directory or move it elsewhere. Nor is it advisable to delete anything here, as such a step could probably make your applications un-workable or even break your system! If you have many applications installed, you can expect to have a jumbo sized winsxs folder.
    If you delete components from the WinSxS folder like the manifets or the assemblies, etc, you could be in trouble. Each system would react differently. What may work for one could break another! For instance, if you install a program that requires that particular assembly, which you may have deleted, then that program will just not run! Compressing the folder is also a no-no, as it could cause problems during WindowsUpdates or while installing a Hotfix.
    The safest way to clean it, is by simply uninstalling applications which you don't require.
