Windows: Event logs to syslog, alternative to snare?

You want to get windows event logs to another machine, maybe a central log server. Then usually you can use WMI (somewhat limited in eps and memory consumtion can be an issue) or you use some kind of agent. Snare is one of the available tools.

But I just came across another tool but I do not have heard about it and how it compares to snare. Do you?

Windows: Cool tool to solve uninstall issues on Windows Systems

Are you having an issue removing a software from your windows computer? Are you already frustrated enough and don't want to do some registry cleanup and fixing?

Why don't you give a Microsoft Fixit a try. They provide a tool that helps you install / uninstall software.

And as always send feedback about other solution you use.

Make sure you select the advanced download part and get a portable version, that you then can put on your MagicTool stick.
