I noticed that on my Windows 7 64 PC I've lost write/modify permissions, but only under C:\Program Files and C:\Program Files (x86).
I know this because suddenly
1) I can't "Save" any documents under those folders or any sub folders. I can create "New Folders", just can do much in else. It's not simply UAC warnings, it's access denied where any "Save" reverts to a "Save As" and not in those folders. And
2) I also noticed that in Windows Explorer, right click in one of those folders, menu Item "New" only shows one item "New folder" with an interesting little shield icon... In all other folders I get a full list of "New" items I usually see such as New Word Document, etc.
My Windows 7 User ID is the same I've always used, and is "Administrator". The PC is clean, up-to-date with WUS, and virus-free.
Solution I found, which I think is unacceptable: Under Control Panel , Users, if I change UAC (user account control) to the Minimum everything works AOK
. Any setting higher then the bottom setting then I'm back to losing the access to C:\Program Files and C:\Program Files (x86).
Since I haven't changed anything that I'm aware of on my PC I suspect either a) a recent Windows Update or b) something impacted the access rights of these folders where my windows user ID got demoted somehow.
500 points. I can reply with more info or print screens if that would be helpful.
