Need a Script Created to Modify an .ini file

I have an .ini file that contains some entries that I want deleted/modified.  I need a script that can automatically modify the contents of the .ini, and it’s something that would eventually be implemented through a logon script.  Can someone provide a script that automatically modifies the .ini file to delete/modify certain entries? The entries are:

AddInMenus=NCMenu

EXTMGR_ADDINS=NCExtMgr,nDLOLNEMFileWatcheru.dll

<Sometimes the above line will only be EXTMGR_ADDINS=

What I need is the following:

If AddInMenus=NCMenu exists then it needs to be deleted.

If EXTMGR_ADDINS=NCExtMgr,nDLOLNEMFileWatcheru.dll exists then it needs to be modified to:  EXTMGR_ADDINS=nDLOLNEMFileWatcheru.dll

If EXTMGR_ADDINS= exists then it needs to be deleted.

The entries are not static to any particular line, so they’re not fixed to lines 5 & 6.

Hopefully there’s a script guru out there that can tackle this with ease.

Here’s an example of the .ini contents:
