Windows 10: All icon images have disappeared, and can't open app properties

I am sorry that I am of no help to you.

 

Most probably your computer has a Trojan. You may find which Trojan from the Windows Defender program. However removal of this is complicated.

My best suggestion is to you is to back up your data to cloud and ask Microsoft store nearby to clean up your computer.

 

I already scanned my computer with multiple antivirus programs, they all came up saying my PC is fine.

 

OK.
I am going to speculate that your user account is corrupted.
To prove or disprove my speculation, please create another user account, presumably an admin account > logon to it and see if your issue persists.
If not, use that new account for a few days to make sure. If all goes well, logon back on to the corrupted account, backup whatever you want to keep and then delete the account.

 

The new account I made also has the same issue.

 

Can you answer?

 

Windows defender says everything is up to date, real time protection is on, and when I scanned it showed no issues.

 

I am out of ideas.
I apologize.
Someone else will come along to help you.
Good luck.

 

Thank you for all your help so far. If I find no other solution I will do a backup and factory reset.

 

Windows defender can only do so much. This Trojan is insidious. Even after removing it, it still lurks somewhere creating a drive 3 and comes back with windows update. Your best bet is complete clean up. Microsoft store will do it for you free.

 

Is there any way to do this myself at home? I have pretty good tech knowledge, I've worked in IT jobs previously, this so far is the only software issue I haven't been able to fix myself.

 

I ended up doing a system restore, keeping my files but not my installed programs- this solved the issue.

 

My computer also has that problem. I'm running a system scan, and I tried many things. I'm so tired now, can you please help?

 

Do you use 2 monitors? See this thread:
Solved Desktop Icons Have Disappeared - Windows 10 Forums

Another idea on the 2nd page of that thread.
