Hello,
Sorry to hear you are having issues. But, first, why do you need to post with large font size?
Okay on to your issue.
First Issue. I believe those hide search box only available only on Windows 11, Windows Pro and Windows Launcher style. And from what I remember, there is no such option for Windows 7 and Modern style.
Second issue. How do you add that folder? I added a folder and it does not show that arrow.
Third issue. I believe you pinned it wrongly. What you can do is, click on All Programs button. Browse to for example "Calculator" right click on it and "Pin to Start11" should appear. Click on it. This should place Calculator on your Startpanel with correct icon.

Thank you.
