Nějak se tomu moc nechtělo, tak hážu co CMD hodil po zadaní těch tří příkazů po pádu.

The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

For Setclassid and Setclassid6, if no ClassId is specified, then the ClassId is
removed.

    > ipconfig /all                  ... Show detailed information
    > ipconfig /renew                ... renew all adapters
