Windows 9x optimized for
Dial-up connections
Download
This is a registry patch that helps speed up your download by adjusting the Default RCV Window and other settings in the registry. This is designed for Cable modems but should also work
fine with DSL. You can download the Cable / DSL patch HERE. Use
Ispeed to test the throughput speed before and after applying the registry patch and possibly increase your throughput
from about 53,000 bytes/sec. to 160,000 bytes/sec. This is a 3x performance increase and all systems are different, so your speed increase may vary.

Patch Windows 2k/XP not to cache failed DNS entries.

save to your HD, unzip the .reg file, then double-click the filename.

The following patch increases Web page loading speed, by
doubling the number of possible concurrent open connections. For example, imagine a web page has 20 images and some text - in order for your browser to get all these files, it opens 2 or
4 concurrent connections, depending on the Web server. Increasing the number of open connections allows for faster retrieving of the data. Please note that the patch sets some values outside
of the HTML specs. If you decide to install it, backup your Registry first. Changes will take effect after you reboot. Download the patch appropriate for your OS:
