The intuitive way to download iTunes free video is probably recording it using a freeware like CamStudio. Since such tool works as recording any screen activity on desktop, it also works for the video as long as you play it in full screen. Hope it helps.
1. Go to Control Panel.
2. Click Programs > Programs and Features.
3. Right-click the Office application you want to remove, and then click Uninstall. Note If you have a suite like Microsoft Office 365, search for the suite name.
Hope it helps.
Not sure if it will be helpful, if you want to retrieve deleted files on your own, you may try EaseUS Data Recovery, the free edition is fairly enough for getting back lost files...
