I installed 2004 yesterday; computer went totally crazy. Examples: Right-clicking on the desktop gave me only new folder. Attempts to save an edited text file repeatedly denied me the rights to do so, even though checking security settings confirmed I had full rights to the folder in which the document resided. Numerous other problems! Wound up having to do a reset! Now, I'm pretty well back in business, but have a few new glitches: On the Task Bar, I created a Quick Launch toolbar with no problems, But on the main Task Bar, there are icons for Edge, File Explorer, Microsoft Store, and Mail and Calender I can't get unpinned. Right-clicking on them does nothing, and only File Explorer does anything -- clicking on any of the other three results only in a momentary window appearing and disappearing. Also, the Notifications icon in the far right shows I have four messages, but neither single or double left-clicking on it anything. Right-clicking brings up a menu which includes Open action center, but nothing happens when I click on that. So...overall, downloading/installing 2004 has not been an enjoyable experience!
