Windows ignores the share permissions that the registry specifies after you install Windows XP SP1
This article has been archived. It is offered "as is" and will no longer be updated.
By default, when you share a folder in Microsoft Windows XP, the Everyone group only has Read permissions.
This problem occurs because a hotfix in Windows XP Service Pack 1 (SP1) changed the default permissions for newly created shares to be more restrictive than in the release version of Windows XP. In the release version of Windows XP, when you create a new share, the default permission gives all users full access. After you install Windows XP SP1, when you create a new share, the default permission gives everyone Read access.
