Thanks to the anonymous tipster who told us how you can save a couple megabytes of disk space when you install Adobe Reader on your PC. Instead of using the official download link, complete and submit the Adobe Reader Distribution Agreement
to receive a link to the Adobe Reader Enterprise Edition. It's virtually the same as the standard Reader, except that it's meant for large-scale deployments and doesn't include the (rather useless) download manager and the Yahoo! toolbar.
And here is the direct download link
to the current Adobe Reader Enterprise Edition 7.07 for Windows.
