I had the same issue with the internet option under tools changed and no tabs at all. I figured out how to fix it. Below is a step by step procedure to fix the issue

PROBLEM: Internet Options under Tools on Internet Explorer is changed and the General Tab is no longer present. To repair this issue you must fix a data value in the registry. To do this do the following.

CLICK START BUTTON > CLICK ON RUN & type in regedit > this will take you to your registry, where you have to go to repair the issue.

Once there, on the left side there go to the following...
Click on HKEY_CURRENT_USER
then click on Software
then click on Policies
then click on Microsoft
Then click on Internet Explorer
and then click Control Panel.

You will see three entries in this area, they are.....(default) REG_SZ & Programs Tab_REG-DWRORD & General Tab REG-DWORD. To the right of these there is a section with #'s in it referred to as "Data". The Data associated with the General Tab should read 0x00000000 (0)... if that data has a 1(one) instead of a 0 (zero) you need to change that data value back to 0 (zero). To do that do this..... right click on General Tab.........click modify.... make sure here is a dot in Hexadecimal selecting it....and the number to the left under (Value Data) change that number to a 0 (zero). Close the registry edit. After you do this the Internet Option under Tools will be normal again.
