Windows 10: ALL Icons are gone + can't open most File/Folder Properties

So It's been a couple of weeks that I've tried to resolve this issue, with no success. I first asked for help from the HP Community, but have had no success so I'm hoping for better luck here. I will try to summarize everything I have tried below. Hopefully, my post is not too long. But being thorough now about what I've done will save a lot of time moving forward, for both myself and anybody kind enough to help.As the title says and you can see in the image below, all icons have completely disappeared. Im running Windows 10 and haven't done any major updates or made big system changes that

Windows 10 Lock Icon


I am having issues being able to paste files into a folder that has a lock icon on it. I am not the owner of the folder, my boss is. I am using Windows Pro 10 and my boss is using Windows 8.1. I can open files contained within the folder but cannot paste files into the folder. I have opened properties and gone to the security tab and I am listed within the Group or user names list and my permissions are all at allow. Any suggestions?

Change Folder Icon in Windows 10


I just acquired a new laptop running Windows 10 and am trying to change the icons of the folders in the StartUp "Program" folder so that they would stand out a little better. I used my admin account and followed all the steps listed above, but when I clicked on "Apply", nothing happened. The same basic windows folder icon remained attached to the folder. I also tried to go into Properties and capitalize some of the folder names, but that didn't work either. Looks like something is protecting them, but I cannot figure out what it is much less how to get around this blockage, Any suggestions?
