PropertySystemView is a portable tool that allows you to view and modify the properties of files using the Windows property system.
PropertySystemView comes displayed from an easy-to-navigate UI. It allows you to easily change the 'Media Created' timestamp stored in .mp4 files (System.Media.DateEncoded) as well as other metadata stored in media files and office documents. This also includes changes to Title, Comments, Authors, Tags, Date Acquired; Last Saved Date, Content Created Date, Date Imported, Date Taken (EXIF of .jpg files), and more.
After running PropertySystemView, you can easily view a file's properties by dragging it from Windows Explorer into the main window of PropertySystemView. You can also click the Browse button and choose the file to open and then press F8. Optionally, you can also access a window's properties by dragging the target icon on the toolbar into the window or by choosing 'Load properties of the following window' from the combo-box, typing the handle of the window (i.e., 01CC0B06), and then pressing F8. If you want to view the list of all properties available on your system, choose 'List all properties on your system' and press F8.
PropertySystemView also allows you to set the properties of Windows. For example, you can set the System.AppUserModel.ID property of a window to disable the taskbar grouping of the specified window.
