Computer tutorials

This is the Todo sobre informática tutorial index. Guides are organised by topic so that you can find an explanation, answer a question or learn to use a tool without searching the entire site.

Where to start

If the problem concerns your computer, look at Windows, software or hardware. For connections and access to services, start with networking and internet. Databases and CMD cover more technical topics, while security brings together advice on recognising risks and suspicious messages.

Before following a procedure, check that your operating system, version and device model match the guide. Back up important files and test changes one at a time. Older guides can serve as references, but their screens or requirements may have changed.
