Try resetting Winsock entries to its default installation. Here’s how: a. Click Start, select Run, type cmd and press Enter. Type: netsh winsock reset catalog in the command prompt and press Enter. Method 2: Reset TCP/IP stack to installation defaults. TCP/IP can sometimes become damaged or corrupted.
- Resets IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log. Netsh int ip reset reset.log need reboot. Way 3: Run ncpa.cpl as Administrator. Right-click the network connection which you are using, and then click Properties. Click on Internet Protocol TCP/IPv4. Click Install then. Click Protocol, and then click Add.
- The process known as TCP/IP Driver or TCP/IP Protocol Driver belongs to software Microsoft Windows Operating System by Microsoft (www.microsoft.com). Description: Tcpip.sys is an important part of Windows, but often causes problems. The file tcpip.sys is located in the C: Windows System32 drivers folder.
- When you need to install or reinstall TCP/IP or install another protocol, begin by following these steps: Click Start Control Panel. Click Network And Internet Connections. Click Network.
- On the General tab, click Install, select Protocol, and then click Add. In the Select Network Protocols window, click Have Disk. In the Copy Manufacturer's files from text box, type c: windows inf, and then click OK. Select Internet Protocol (TCP/IP), and then click OK. Restart your computer.
I can not explain what has happened, just suddenly I lost my internet connection. On local area connection properties IPv4 is not installed, my ISP says that they only support IPv4. Then I must had it because I had connection before. What could happen to lose IPv4? And how to install it back?
Thank you.

You can run regedit with SYSTEM rights by using PSExec too, much smaller download. One of the examples they post is running regedit as SYSTEM.
Reboot!

From the Device Manager, navigate to Network Adapters and expand the tree. Right click and uninstall the ethernet card and reboot. Windows should autodetect the card and reinstall the appopriate drives. This should re-enable IPv4.
