As for privacy, you can set up Edge so that it doesn't offer to save passwords and so that it doesn't save form entries. In particular, you can ask Cortana certain things and she'll display answers from within the search bar, without you having to open a page.
For example, you can type in unit or currency conversions, get a simple weather forecast or look up stock quotes.
Here are the instructions on how to set virtual memory (paging file) for XP.
The icon farthest to the left is where you'll find your favorites, browsing history, downloads and your so-called Reading List, which I'll tell you about shortly.
Meanwhile, the icon all the way on the right brings up various settings, including the ability to swap out the default white theme for a black background.
Click the Advanced tab, and then under Virtual memory click Change.
Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
