Your personal attacks on this person are unwarranted.
I'm trying to find a solution to the proposed problem, and your workaround doesn't work. I tried it.
When I depress the almighty shift key in addition to pressing the delete button when I have a file selected, I am still prompted with the inquiry of whether or not I want to delete the file. No force deletion happens.
Furthermore, as I said, this is a workaround. Not a solution.
The problem at hand is in using windows 8, when a user has a the Preview Pane option available, any PDF that uses Adobe reader normally, can't then be deleted after it's been "previewed".
Workarounds instructing people to stop using Preview Pane and to force delete the file are just that, workarounds, and not solutions.
Force delete doesn't work for all computers, apparently.
Telling users to simply stop using a feature is not a viable solution.
Switching to another PDF reader to avoid the problem is not a viable solution.
Microsoft Support, please review this problem and suggest a real solution. This is unacceptable for the time the issue has existed. I need to use preview pane, I need to use Adobe software. I do not want to force delete objects. Please provide a solution.
