Before the many updates to Skype post-Microsoft acquisition, simply disabling the promotions options in settings was enough to rid your conversations of unnecessary spam. However, a new banner ad has made its way to the conversation window. This ad wouldn’t be such a bother if it didn’t often cut into the video feed area when going full screen.you can disable ads through just a few steps. Here’s how:
Step 1: Quit Skype
Step 2: Goto %appdata%\Skype
And find your username
Go into that folder
Step 3: Find config.xml
Step 4: Edit the file and find <AdvertPlaceholder>-1</AdvertPlaceholder>
And delete that string
Step 5: Save changes and mark the file as Read only (So Skype doesn't edit itself lol!)
Done.....share it Thanks
