I have 100 team sites in SharePoint 2010. At the last minute, I have been asked to hide a tab on each of these sites. Through the GUI, I could do this by using the Navigation option under Site Settings, but I would have to do it for all 100 sites. Is there a way to do this programmatically? Or globally through the GUI (I doubt this is an option)? I have tried using JQuery, but due to the lag, it is not a viable option. I figured there may also be the possibility to write a powershell script to do this - I am just still new to powershell.
