For beginners and experienced users
Easy to approach. Detailed when you need it.
Whether you want a clearer picture of your home PC or need technical details for a diagnosis, TN Care brings an accessible overview and in-depth information into one application.
Technical depth for experienced users
Detailed hardware identification, supported sensor readings, process and drive activity, network quality and measurement histories provide a basis for closer analysis. This helps with troubleshooting, maintenance and preparing a hardware upgrade.
A look inside TN Care
Clear views. Useful answers.
Explore the interface with actual application screenshots.
01 / Your PC at a glance
See what is using your computer.
The dashboard brings live CPU and memory instruments, GPU readings, network traffic, processes and drive activity into one clear view. Follow changes over time and identify resource-heavy applications before choosing your next step.
- Computer check combines system and hardware results with a visual progress display.
- Antivirus and firewall status are shown where Windows makes the information available.
- Performance views include energy profiles, optimisation suggestions and a RAM assistant.
02 / Hardware identification
Hardware details beyond the model name.
TN Care takes a detailed look at the components in your PC: mainboard model, processor, memory, graphics, drives, BIOS, drivers and monitors. Component information and available diagnostic readings help you prepare an upgrade, investigate a problem and describe the system precisely.
- Utilisation and supported temperature readings help put current activity in context.
- The mainboard model is detected; the 3D illustration is a standard representation.
- Available readings depend on your hardware, its sensors and the interfaces it exposes.
03 / Network diagnostics
Find out where your connection is struggling.
Is the connection slow, unstable or simply busy? TN Care combines adapter information and live traffic with latency, jitter, packet loss and DNS checks. The Internet–gateway–computer diagram makes the connection easier to follow.
- Inspect Ethernet and Wi-Fi, local link speed and available IPv4/IPv6 connection details.
- Compare connection quality with current network activity.
- Link speed describes the local connection; it is not the measured Internet download speed.
04 / Network analysis & Mesh
See connections. Understand your network.
The visual network view makes devices and available connection paths easier to follow. LAN, Wi-Fi and Powerline are visually distinguished. With a supported router and access permission, Mesh information adds further detail to the overview. Inspect reachable devices, test connections and open detected web interfaces directly.
- Device details and manufacturers are shown where they can be identified.
- Router, TR-064 and Mesh information require a compatible router and the corresponding access permission.
- The visible topology depends on the available router data; it may not include every device or connection.
New in version 2.2.7

- Regular availability checks for servers, websites and network services
- Individually configurable check intervals and timeouts
- Monitor up to 20 targets
- Email notifications for confirmed outages and recovery
- Clear local long-term log with status, timestamp and response time
- Filterable reports with Excel or PDF export
- Reliable background operation in the system tray
- Enable or disable monitoring and individual targets at any time
Diagnostics, cleanup & maintenance
The right next step for your PC.
Review the results, choose an action and keep track of what changed. These tools help with everyday maintenance and a closer investigation of problems.
PC cleanup
Analyse cleanup categories, review the file preview and select what to remove, including the thumbnail cache. You decide which suggested actions to apply.
Duplicate files & quarantine
Search selected locations for duplicate files and move selected entries to quarantine. In settings, restore entries or confirm their removal and configure retention.
Drives & storage
Review capacity, usage, supported technical data and read/write activity for internal, USB and network drives. Run file-system checks and appropriate optimisation for local media. SMART data requires a supported interface; network drives are not optimised locally.
Software & startup
Search and filter installed software, confirm uninstallations and optionally check for leftovers afterwards. Enable or disable startup entries to manage what launches with Windows.
Games & applications
Adjust software priority for games and other programs, see the priority that has been set and reset it when needed. Performance views help you assess resource usage.
Speedcheck & long-term measurements
Measure Internet download and upload with live curves and quality readings. Configure automatic tests while TN Care is running, compare 24-hour, 7-day and 30-day views, and print a report. This is a practical diagnostic tool, not an official broadband certification.
Speedcheck & long-term test
See how your connection performs over time.
A single speed test shows one moment. TN Care combines an immediate download and upload measurement with configurable repeated tests, helping you compare results and recognise fluctuations over time.
