Annuity death benefits are not often paid because most annuities are surrendered, transferred or annuitized for income prior to the death of the annuity owner or annuitant. The death benefit is often an afterthought, yet it is one of the more important components of the annuity contract.
To get to Disk Cleanup... Open File Explorer or My Computer. Right click the (C:) drive, and select Properties. The Disk Cleanup button is in the first tab that opens. This works in Windows XP and probably earlier, as well as on Windows 7, 8, and 8.1 - probably in Win 10 but I haven't tried that yet.
In order to remove it you must use the Disk Cleanup program on Windows 10. To do this click on the Search icon in the taskbar or tap the Windows key to open the Start Menu and just start typing Disk cleanup (1). You should see the Disk Cleanup program entry at the top of the search results (2).
