While the term Winsock might not sound important to average users, a broken one can render an Internet connection dead to the world. This free utility makes quick work of fixing corrupted Winsocks caused by both malicious and nonthreatening programs. LSP-Fix's developer suggests you read the documentation before using the app, and unless you're a highly technical user, you should follow this instruction. Likewise, don't check the Advanced check box unless you know exactly what you're doing. The main interface is bland looking but mercifully easy to use; one pane shows you Winsocks you should keep, the other shows problematic ones that may be causing your problem. When testing this program with a disabled Internet connection (courtesy of a borderline suspicious program), we were pleased by both its effectiveness and speed; our connection was back up in seconds without even the need for a system restart. This program only does one job, but it can be a lifesaver in certain sticky situations.
