I can't find this checkbox in the registry so I can have Desktop Authority write it to whatever it needs to be to be UNCHECKED.
I have perused many forums that address the changing of the flag/option on the first tab, IE this Stack article:
How to modify Internet Explorer temporary internet settings with registry?
BUTTTT What I truly want is the checkbox in this screenshot to be turned off (in the Caches and databases tab):
Further Googling did not offer anything but I went through the Registry one by one until I found the key in a spot completely different than the Internet Settings.
Key location:
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\BrowserStorage\AppCache] "AllowWebsiteCaches"=dword:00000000
Setting that as 1 or 0 changes the checkmark within the internet settings. Silly me, thinking the same options panel would have registry keys in the same spot! Thanks!
