I just ran UCheck on my desktop and laptop computers. It found three updates for the desktop (Calibre, VLC, and Notepad++) and successfully installed two of them. It refused to download and install Notepad++ Version 8.0. I went the website and downloaded it and updated it manually. Windows 10 Pro Build 21H1, fully updated, running on a Dell XPS 8930 SE desktop. Same thing on my Dell XPS 15 7590 laptop, running Windows 10 Pro, Build 21H1, fully updated.
I have attached report and screen image from the desktop. Nothing appears when I hover over the "X".
After manually updating Notepad++ Version 8.0 on both computers, UCheck no longer reports the update as being available.
Thank you and have a great day.
