Delegate is a great way to implement Callback operation. But, interface is good for the implementation of Callback in different scenario which I have mentioned above. Please read carefully and understand the code snippets. I have also attached code files. Writing code is good but code with proper design approach increases the quality of code.
Windows Vista and Windows 7 make use of a c:\windows\winsxs folder to store backups of various install files and/or files replaced by updates. I'm not completely certain on everything Windows stores there.This seems to be completely separate from System Restore.he WinSxS\Backup folder: In previous versions of Windows, such as XP there was a component called 'Windows File Protection' which was used to make sure that all of the many system files were protected and backed up. These files were backed up in the %systemroot%\System32\dllcache folder.
In Windows 7, there isnât a âdllcacheâ folder and nor can you find the âi386â folder, where the system caches (like in XP) all itâs source modules. It is this WinSxS folder which stores the shared components of side-by-side applications. These files can be multiple versions of the same assembly or application.n Winsxs the âbackupâ folder is the largest as can be noticed in the image below. Again, as can be seen in the image below, in the Winsxs folder, the âOtherâ File types takes the bulk of the space.
