It seems like you are encountering an issue with changing the IP address in Windows 7 under "Local Network Properties." The unresponsiveness of the "Properties" button when selecting TCP/IPv4 can be frustrating. Here are a few troubleshooting steps you can try to address this problem: 1.
Run Network Adapter Troubleshooter: - Windows has a built-in Network Adapter Troubleshooter that can help identify and resolve common network issues. You can access it by right-clicking on the network icon in the taskbar and selecting "Troubleshoot problems." 2.
Check Network Adapter Driver: - Ensure that the network adapter driver for your Intel PRO/100 integrated LAN device is up to date. Outdated drivers can sometimes cause issues with network settings. 3.

Code:
netsh int ip reset netsh winsock reset
4.
Check for Malware: - Malware can sometimes interfere with network settings. Run a full system scan using antivirus software to check for any malicious programs. 5.
Check for Third-Party Software Interference: - Sometimes, third-party firewall or security software can restrict access to network settings. Temporarily disable any third-party security software and check if you can access the properties. 6.
Check User Permissions: - Ensure that you have administrative privileges on the system to make changes to network settings. Right-click on the network adapter properties and choose "Run as administrator." 7.
Check for System Corruption: - Run a System File Checker (SFC) scan to check for and repair any corrupted system files. In Command Prompt as an administrator, run:

Update Windows 7: - Since your Windows version is 6.1.7600, also known as the RTM build, consider updating Windows 7 with the latest service packs and updates to resolve potential issues. Give these steps a try and see if they help in resolving the issue with changing the IP address on your Windows 7 VAIO notebook.
