We have updated 6 machines to Windows 10 over the weekend and one of them has an issue that I hoped would go away with the upgrade but it has not. And of course it's the boss's computer.
When he opens a single excel (2013) spreadsheet it shows up on the taskbar. When he opens a second one, however, the second will replace the 1st on the taskbar with no way of getting to the first even with Alt + Tab. This does not happen with the third, forth or even the twentieth though.
I have reset the taskbar options as I have found suggested on other sites, with no satisfaction. I have reinstalled office and looked for and removed template sheets along with verifying that every setting in Excel->Option
and under Windows 10 Settings is the same as every other computer in the office.
Has anyone else seen this? Is there a suggested fix that I have not tried?
