Hide applications from the useres profile.

Hey guys, sorry I asked for something similar this previous days. I would like to hide the "Applications" from the top menu. (image1)

Would I still be able to set the applications I want my users to have by default in the backend right? I just don´t want my users to install apps on their own, I want them all to have the same apps installed.

And also: can I hide the Search Appliclations in the apps module on the profile? (image2)

Thanks guys!
