More Windows 8..... Missing Files ?

If your Internet Explorer 10 is set for 'InPrivate Browsing', that may explain why you can't find any Temporary Internet Files....

InPrivate is turned on

When InPrivate Browsing is turned on, you will see this indicator

InPrivate Browsing helps prevent Internet Explorer from storing data about your browsing session. This includes cookies, temporary Internet files, history, and other data. Toolbars and extensions are disabled by default. See Help for more information.

And you change or access that from the Tools menu dropdown list in your I.E.

(and as one commenter in their forum said 'I learn something new every day')

So if you want to see those missing files, just turn off InPrivate Browsing. But don't forget to turn it back on again.
