So as the topic states the icons dissapear randomly and i've followed the page under here and i know this issue isn't precisly new. Notification Area Icons - Reset
=Taskbar Start Menu
Helps for awhile then bam they go and dissapear again, not all of them but some and it annoys me to no end, just to be clear i'm not THAT used to 7, been using old XP uptill max 2 months ago as i built myself a new pc, sp1 is allready installed and all updates i could get my hands on via windows update.
I've made 7 to behave a litle like XP cause i didn't like how 7 did it :P like... got rid of the huge icons next to the start button and made a new "quicklaunch" area and have all the icons near the clock show themselfs but as stated they tend to dissapear even if the programs are running, checked via task manager.
So don't know what else to add but that's the gist of it i guess, there should be 9 icons there minus the network icon i disabled cause i didn't need it.
A reboot or relogin sometimes helps but not everytime.
