Every morning my computer starts up different. Sometimes icons are missing from the tray, sometimes not. I have run scans and no viruses are showing. I have windows xp ???
what CPU… how much ram ?
have you done a clean up http://filehippo.com/download_ccleaner/
If you are talking about a specific icon in the tray area, you can set it to be displayed “always”.
Generally speaking, if you have “many” tray icons, then the icons in the tray area may be hidden until you use the program more frequently. This behaviour can be changed in the task bar properties.
