[sfareg]

1- if i downloaded update till today 21-8-2015 can in future resume the new update or download in beginning
2- if i use wsus offline 9.6 and want to update to wsus offline 10 how can do this without delete old windows update that downloaded by wsus offline 9.6

1) wsusou will just download new updates and delete superseded ones, if you start a new download run. (If you enabled the "Cleanup download directories"-option)
2) wsusou has a built-in self update, which will update the scripts. If you want to, just overwrite version 9.6 with 10.0. When starting the download the first time, wsusou will clean up the old code.
