Small checks. Clear next steps.

Computer running slowly: where to start

1. Save your work, close applications you do not need, then restart.
2. Check whether the slowdown affects one application or the whole device.
3. Check available storage and remove only files you recognise and no longer need. Back up important files first.
4. Open Task Manager on Windows or Activity Monitor on macOS to see which applications are busy.
5. Note when the slowdown started and any recent update or installation.

Avoid registry cleaners and unfamiliar optimisation downloads. Report persistent errors before attempting resets.

Before installing or updating software

1. Get the installer from the software publisher's official website or your operating system's app store.
2. Check compatibility, storage requirements and licence details.
3. Save your work and back up important documents.
4. Read each setup screen and decline optional extras you do not need.
5. If setup fails, copy the exact error and application version. Do not repeatedly disable security settings to force installation.

Wi-Fi connection checklist

1. Check whether another device can use the same Wi-Fi.
2. Move closer to the router and check whether the signal improves.
3. Check cables and router lights without changing its settings.
4. If it is your router and no one needs the connection, restart it normally. Do not press its factory-reset button.
5. If all devices remain offline, check for an outage with your internet provider.

For a support request, include the router model, affected devices, and what you observed.
