Question : WSUS headaches - accidentally picked too many updates and now cannot remove; also some duplicates appear to be showing?

I am trying to figure out WSUS but I've hit a few issues. First, I am new to this office and do not frankly know if it was ever used or if anyone attempted to set it up but 3.0 is installed. I opened it under admin tools and played around a bit, and got it to do a massive synchronization. Now there are about 2,500 updates listed (not downloaded but they show in the all updates field). I realize that most of these are not even remotely relevant to my needs and I have figured out how to control which updates are even checked when synchronizing, so I would like to completely clear this field and start over, unchecking the things I don't need before doing another synch so I will only see relevant updates here. I cannot figure out how to remove them however! They are not downloaded as I said, but I am afraid to decline them all as won't this prevent them from being shown in the future? I am sure there are some updates in there that I want/need but I cannot really sift through all 2500 to find and approve the necessary ones! Also, some updates appear to be duplicates... how/why is this happening? (see 2nd image) Lastly, when I view computers, nearly every workstation has a yellow exclamation mark and says it has not checked in for a large number of days (37, 52, etc) which I do not understand as these computers are signed into on the domain every day. I have attached some images for reference, any help is greatly appreciated thanks!

I would leave it as, and configure the way that you want approvals to be done. A high percentage of these will most likely have been already installed on the machines anyway. Alot of them will also have been superseded by newer updates(listed more than once). This is what it looks like on a new install of WSUS.

save the below as fixwsus.cmd and run on the clients.
