I installed Windows 10 (upgrading a Windows 7 Toshiba Laptop) several weeks ago and everything seemed to be working fine. A few days ago I started to see that when I went to close down the laptop "Task Host stopping background tasks" If I cancelled the shutdown (thinking something was still updating) no matter how long I left it (tried up to 2 hours once) when selecting shut down again I had the same thing. So I was forced to select "Shut down anyway" I have looked in the update settings when this is happening and a row of dots are running across the top of the page. Indicating to me it's doing some sort of update. But what? I have seen other topics talking about Firefox, is this possibly the problem. I was previously used IE and Firefox occasionally. As IE has been replaced by Edge I thought I should try to use this instead, but as soon afterwards I got a message saying NORTON (as yet) was not supporting Edge and I should not use it (or something like that). I then changed my defaults to Firefox (my second choice). I am wondering what Windows 10 is doing to all my favourites from when I used IE. Is this causing the issues. At times when I return to Firefox for a second time, I get a message saying Firefox is still open! And I should close it. I don't understand this and I can't find anything to confirm that it's indeed already open. Having tried to open Firefox for a second time, the Laptop works so slow it's almost unusable. The only way is to force a shut down and start again, it's then OK till you try and open Firefox for a second time. Any thoughts?
