System Nucleus is a powerful suite of tools for optimising, managing and controlling your PC.
There's a module to display your Windows startup programs, for instance. And not the short list available in similar utilities. This one includes services, codecs, Windows extensions, known DLLs, drivers, everything. It's easy to filter the list in a variety of ways, and you can disable or delete items in just a few clicks.
A useful Event Logs viewer is far easier to use than Windows own version: just check boxes to choose the logs you'd like to examine, then click the event types of interest (Errors, Warnings, Info and more), then browse the report. Don't understand something? Another click will open a browser window at EventID.net with more information on that particular event.
A Disk & Drives module displays drives accessible from your PC, then can check these for errors, analyze, defragment them and more. A Backup and Recovery tool is able back up Registry hives, event logs or drivers, and a System Editor allows you to configure thousands of system settings from a single straightforward interface.
System Nucleus can be annoyingly slow, with some modules taking a minute or more to launch, even on a fast PC. It's multi-threaded, though, so if a hard drive analysis is taking a while, then you can always open tabs for your Startup Programs, Running Processes, Drivers or anything else, and they'll all launch simultaneously.
