Windows

Often an extra line at the bottom of the screen would be useful.  We sort of created one by setting the taskbar to auto hide (right click on the taskbar/Taskbar settings/Automatically hide the taskbar in desktop mode).  We didn't stick with it long, the task bar doesn't respond immediately and you then have to move the mouse to the wanted icon ... but it may suit you.

It seems that Microscoft have been pratting about with the photo viewer in the latest Win10 upgrade.  The slideshow icon has disappeared but user key f5 will do it; and there's now a different response to the magnifying glass zoom so useful to know that Ctrl + mouse wheel will zoom a pic.

It worried us for quite a while that the Windows 10 accent system colour kept changing all by itself on a desktop.  It was happening because we'd set the background to slide show and when the graphic changed so did the accent colour.  Fix it by Windows Key/Settings/Personalisation/Colours and uncheck the Automatically pick an accent colour ... box.

Here's one from 2011; when defining a group click on a file, then click on another whilst holding down the Shift key and all the files in between will be added to the group.

At ntc the main desktop pc has two monitors so we've haven't felt the need for virtual desktops, indeed they just confuse us ... but we are easily confused.  Before meddling with virtual desktops ensure the task view button is visible and note that Windows key + Ctrl + f4 closes the current desktop.

The Windows 10 Anniversary Update took forever here, forced multiple reboots with the last reboot leaving a desktop hanging and we had to force our own reboot.  If like us you've previously turned Cortana off annoyingly the update turns it back on and removes the on/off toggle.  How-To Geek have a download (halfway down the page) that's a one click fix.

You start up your pc/laptop (or perhaps it restarts itself) and you get something like Operating System not found, perhaps you've left a memory stick in a USB port and the pc is trying to boot from that?  Just remove it and maybe change the device order in which the pc's BIOS looks for the operating system, quite how you do this will depend on your particular pc, Google it.

In Windows 10 lots of the old favourites like Control Panel aren't immediately apparent, point the mouse at the Windows button bottom left (unless you've moved the task bar) and click the right mouse button (if you're right handed) to get this useful menu.
