What is TweakMASTER?

Tested compatible with Windows 7 TweakMASTER has been the NUMBER ONE Internet Optimizer utility for 9 years, developed by the leading pioneers in the field. Rose City Software distributed the very first full featured Internet Optimizer back in the late 90's with Windows 95, long before many of our would-be competitors had purchased their first PC! And we have been updating it and improving it constantly.

TweakMASTER version 3.0 is the most effective, full featured and easy to use TweakMASTER yet! Supports ALL current Windows™ versions including Windows 7/8/10 and AOL software too! No other utility can make that claim and deliver!

TweakMASTER promotes faster Internet download speeds by carefully and intelligently tweaking various 'hidden' Windows settings. It provides powerful Internet Boost for ALL types of Internet connections including dial-up, cable modem, DSL, or satellite, and especially for Wireless as well!

Praised by both individual users and large companies alike, TweakMASTER Pro is the best utility of its type available, and has site licenses in place with Microsoft, ATT Wireless, Arizona State University , BizarNet - Satellite Internet Services, Bytemobile, Inc., Kansas Building Systems and many other major companies. TweakMASTER PRO includes the award-winning DU Meter, which has additional site licenses in place with Intel, Nokia, SunGard Assent, ATT Wireless, Alcatel, Lucent, Raytheon, InfoSys, JPMorgan Chase, Sierra Wireless, Fourelle Systems, Nortel, Reuters, Texaco, Compaq, Belgacom Mobile, Telecom Mobile Pte Ltd, Mobilkom AG (Austria), Oklahoma State Department of Human Services and many other major corporations.

Besides the indispensable DU Meter, the PRO version of TweakMASTER includes the award-winning LinkFox which is explained in more depth on a separate LinkFox page. LinkFox is a true second generation web accelerator software, which is compatible with Internet Explorer 6/7/8. Previously sold separately for $24.95, you can now get LinkFox free as part of the full suite of tools in TweakMASTER Pro.

And look at all the awards TweakMASTER Pro has won! Just what you would expect from the leaders in the field of Internet Optimization!

How many times have you sat there waiting for a page to download from the web, and waited for what seemed like an eternity while the numbers in the status bar just seem to stall or barely creep along at ridiculously low transfer speeds? It could just be an overloaded server on the other end or general Internet congestion, but it might also be a problem with the way your Windows operating system is configured.

Here at Rose City Software, we drew from our vast experience with the Windows™ operating system (Rose City is part of the world reknowned Rose City Software/HelpWithWindows network). We came up with a simple yet effective way to dramatically increase your download speeds. Although many utilities claim to speed up your connection, they can actually do more harm than good, by changing the wrong settings in your registry for your version of Windows. Designed by a team of network engineers at Hagel Technologies, TweakMASTER delivers where others fail. Don't take chances... go with the proven leaders in the field!

How The Internet Works

The Internet uses a protocol called Transmission Control Protocol (TCP) developed in the 1970s by network engineers at Stanford University and others. Basically, it breaks down large files into small packets of about 1500 bytes, each carrying the address of the sender and the recipient. The sending computer transmits a packet, waits for a signal from the recipient that acknowledges its safe arrival, and then sends the next packet.

If no receipt comes back, the sender transmits the same packet at half the speed of the previous one, and repeats the process, getting slower each time, until it succeeds.

This means that even minor glitches on the line can make a connection very sluggish. That's where TweakMASTER can help!

TweakMASTER is easy to use and requires no special computer knowledge. No matter what speed you connect at or what other utilities you may have tried, nothing will provide a FASTER Internet connection for you than TweakMASTER... guaranteed! TweakMASTER can substantially improve your download speeds for all types of connections from dialup to DSL, Cable, and Wireless. Even AOL users will be amazed at how much more responsive their system will be!

TweakMASTER also includes a comprehensive set of tools to help optimize your connection. These include an innovative DNS Accelerator which helps websites load much faster, as well as Advanced Ping and Traceroute, WhoIs, A DNS identification client, a Connection Throughput measurement utility. At a time of increasing concerns about Internet privacy, spyware and other vulnerabilities, TweakMASTER now provides a Network Connections Viewer for added security as well as automatic monitoring of your Windows Internet Connection Firewall. To round out the suite of tools, TweakMASTER also includes a handy PC clock synchronization utility and Connection Minder. Using the simple Wizard, TweakMASTER can easily double your download speeds and make 'Surfing the Internet' a truly exhilarating experience.

Be the Master of your Internet connection...

Comments from TweakMASTER users

"This program has doubled my download speed  from an average 3.5k/s to a new average of 5 - 6K/s...with a "High Point" of 12.6k/s. This was using the default setting for Windows. The program is very "point and click"...very easy to follow and understand. Everything worked as promised! Overall...a great little program that I could not do without, having seen it in action!"
Dan Corkery <>
TweakMaster keeps the promises you made. It optimized my internet connection though it had been 'optimized' already by another program. The TweakMaster is easy to use and - which is even more important - successfully improved my i-net connection. Congratulations - on this great program!
Markus Schwarz <>
Used with my dialup connection and USRobotics V.90 modem, the wizard did all the work choosing the correct settings. Tweak/MASTER tripled my download speed from 4.1Kb to 12.6Kb!!! I loved the increase.
