So Afraid You might have the right line because I did in fact install an old MS Combat WWII Flight Sim. Not into games at all really and hadn't installed it since I first used XP about 3 or 4 years ago, and I made an Acronis backup first.
The installation was straightforward and the game plays normally. I hate intermittent faults!
northumbria61 A smart bit of searching thank you, but the post is now 7 years old and not quite the same problem
I find this interesting as it is not dissimilar to the problem I have had for some time in that not all those items which would normally load and show an icon in the right hand Taskbar always do so. I thought I had cured the problem by clearing out old e-mails and other rubbish - I was wrong.
But those items not showing icons in the Taskbar do appear in Task Manager and if closed there and restarted from Programs the icons immediately appear.
I have also had instances where a program (mainly HDD Health) appears twice in Task Manager - when this occurs the history data on the drives is corrupted.
Often, I find either a Restart or use of Ccleaner followed by a Restart causes the 'normal' display of the icons.
I have tried many different ways to totally resolve this but to date all have failed. Things tried also include starting my router after the PC has booted fully; but this has had no effect for me. I should add that I always turn the router off when I turn the PC off.
