1. Windows system properties like fetching Windows OS version, JVM version, OS architecture, Java Version, OS name, Windows user name etc.,
2. Fetching Windows BIOS serial number.
3. Fetching memory details like
- Virtual Memory Size
- Free Physical Memory Size
- Free Swap Space Size
- Process CPU Time
- Total Physical Memory Size
- Total Swap Space Size
4. Fetching network interface and Adapter details
5. Fetching system hard drive details like each drive total and free space.
Lets see a Java code which will fetch a complete information as we discussed above.
