Complete Internet Repair Portable

Complete Internet Repair Portable is an application with several features for attempting to fix faulty network connections. It tries to repair Winsock, reset the TCP/IP and proxy server, and so on.

Doesn't need setup

Since installation isn't necessary, you can extract files from the downloaded package, save them anywhere on the disk and just double-click the executable to bring up the main app window. Also, thanks to its small size, you can store Complete Internet Repair on a USB flash drive and effortlessly run it on your friends' PCs to try and fix their Internet.

Check out descriptions for each network repair function

There's nothing much to be said about the interface. It's made from a single window that shows all fixing options right from the start, as well as a menu bar that opens additional areas.
Before hasting to click "Go!", you can explore the list of options and, if you're not tech-savvy, click the "i" button next to each entry to find out what it means. For example, you can flush the DNS to refresh all DHCP leases and re-register the DNS names, repair SSL or HTTPS connections if you're having trouble with secured websites, such as the ones that deal with banks, as well as reset the Windows Firewall configuration to factory mode if you don't remember the settings recommended by Microsoft.

Reset the Internet Protocol and Winsocks, among others

Worth mentioning is that multiple boxes can be ticked before clicking "Go!" in order to carry out multiple tasks without your intervention. This way, you can leave the PC unattended to handle other tasks while Complete Internet Repair Portable is busy fixing your Internet. Experienced users can view log detailed on the bottom size of the window.
As far as program preferences are concerned, you can disable or just clear logging, ask the tool to back up information before removing anything, open the Windows Event Viewer, and reboot your PC without leaving the GUI.

Easy-to-use Internet repair tool

Moreover, you can restore the OS to a previous state, start the Windows Internet Troubleshooter, run an Internet speed test and get router default passwords using a couple of websites, view your TCP/IP configuration in a command-line window, as well as list your Winsock LSPs in a text editor.
All aspects considered, Complete Internet Repair Portable provides you with simple solutions for repairing your Internet connection in common scenarios. It's mainly dedicated to users who don't have enough experience to manually resolve these issues.
