Enable More Simultaneous Downloads in Internet Explorer

Have you ever tried to download more than 2 files from the same website and noticed the third download doesn't start until one of the prior two are done? The reason for this is that the HTTP 1.1 spec says that only two connections may be allowed at a time, so your browser adheres to that limit.
We can boost that number for IE by using a registry hack, but let me warn you not to go crazy and increase it too far.
If everybody increased the number of connections it would really put a hurting on the webservers out there, and then webmasters would have to start blocking extra threads.
Manual Registry Hack
Open regedit.exe through the start menu search or run box, and then browse down to the following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
On the right hand side, you'll want to create two new 32-bit DWORD values:
MaxConnectionsPerServer - This sets the limit for HTTP 1.1 servers, which is normally supposed to be 2
MaxConnectionsPer1_0Server - This sets the limit for HTTP 1.0 servers, which is normally supposed to be 4
You can change the amount of connections for either one by changing the value, but I wouldn't try and crank it up too far, as you'll find your browsing becomes much slower than normal, and possibly would get you blocked from some servers for using too many connections. A safe bet is to double the defaults.
Downloadable Registry Hack
This downloadable hack will only slightly increase the values, which is probably the wisest course of action. You could modify the script to use more if you'd like.
You can download, extract and double-click on the registry file in order to enter the information into the registry. To uninstall, use the uninstall script included in the zipfile.

Print Pages in Internet Explorer 7 Without Headers or Footers

The headers and footers that always print along with the page when printing a page can be irritating. I know very well what page it was I printed, so it's not useful to me to show the URL at the bottom of the page.
If you want to turn the headers off just for a one-time print, you can use the Print Preview window, and then click the button to "Turn headers and footers on or off", shown below.

If you want to permanently turn these options off, you can use the Page Setup option instead.

Just click on Page Setup, and then you should see this dialog.

You can just remove the text in the textboxes completely in order to get rid of the headers and footers, or you can change the options to display page numbers at the bottom, or really any combination you want.
Here's a full list of the options that you can use (You could also find these in the Vista help files, or possibly the IE7 ones)

&w - Window Title
&u - Page URL
&d - Date in short format
&D - Date in long format
&t - Time in regular format as shown on the clock
&T - Time in 24-hour format
&p - Current page number
&P - Total number of pages
&b - right align the next text. (You can see it in the default header, where &b is placed before the Page text)
&b[TEXT]&b - If you surround the text in &b on either side, it will center the text.
&& - A single ampersand (&)

You can combine these in any format you want. For instance you could do this:

I printed these &P pages on &d at &t

Which would give you something like this:
