    I am from China. I find the perfect solution. ie, you don't have to disable Cortana.

    1. Change the (default) value of the following key:

    [HKEY_CLASSES_ROOT\Excel.Sheet.12\shell\Open\command]
    [HKEY_CLASSES_ROOT\Excel.Sheet.8\shell\Open\command]
    to:
    "C:\Program Files\Microsoft Office\Office15\EXCEL.EXE" "%1"

    2. Remove or backup the command subkey
    3. Remove or backup the ddexec key

    Thank you so much! Works for me too. Brilliant stuff.

    While this will work, I think it means that multiple spreadsheets are then opened in the SAME instance of Excel, rather than separate instances. Or is that not the case?

    registry gets updated after restart and all changes are reverted... Is there any way to keep the edited files after restart? Would changing some permissions in regedit work? If so, which ones?

    Thanks.

    I have 64bit office btw.

    Same issue here since moving from Windows 8.1 to 10, also with Office 365. The issue with Excel is tied to DDE -- which appears to be the common factor here between Excel and Cortana. With Cortana turned off, Excel can start up with the default command line switch -- including "/dde" which, I believe, has Excel open newly double-clicked files in a single instance of Excel (default behavior for the past few years). Changing the command line arguments and removing "/dde" will open files in separate instances I believe -- probably less efficient use of memory and resources in general, but with modern machines this likely isn't an issue.

    I found Cortana amusing, but Google Now is still far more functional, so it's not an issue for me to put Cortana back on the shelf until Microsoft gets this DDE issue worked out. That way I can leave Excel in its stock configuration.

    While like most people here I first noticed this issue with Excel, that is not the only program I have found to be affected. Once I disabled the "Hey Cortana" feature, I found that a problem I was having with at least one other program that was slow or working incorrectly was immediately resolved. I was able to confirm this by disabling and re-enabling "Hey Cortana" multiple times and testing the program (a single use credit card number generator from Citibank) under each configuration.

    My point is simply that it is very likely that more programs than we know are affected to one degree or another by this and solutions like that proposed by VickyLilly, while possibly useful to some, are more of a band-aid than a solution. Just out of curiosity, I'll be looking at a couple of other programs I had questions about later in the next day or so.

    Fortunately for me, turning off the "Hey Cortana" feature is really a very minor loss.

    Disable "Hey Cortana" feature is not enough for me. I need to disable Cortana at all.

    UPDATE: it seems that I managed to find the cause for the problem - in my case, it's Cortana. When I enable Cortana voice commands, the problem appears. When I tried exiting it through the Task Manager, problem stopped until Cortana restarted itself (which it does automatically), but when I disabled Cortana (via Cortana Settings) and then exited the app, it did restart itself but problem didn't reappear. I tried this multiple times and it was always the same.
    OMG THANK YOU! Registered just to say that. This bug has been driving me insane! I wonder if this will be fixed in Office 2016 that comes out next month... either way, thank you. I did have to completely disable Cortana in order for the bug to go away. That bit**!

    I upgraded windows 7 home premium to windows 10 and i did not install Cortina. After the install Excel files had a 10 second delay upon opening them with a double click. Not only that, but after opening one of the Excel files, other Windows10 functions stopped working: the settings window comes up empty; system icons do nothing. I did this registry fix and the Excel files do open immediately; but the other Windows items continue to stop working. Rebooting fixes the windows items, until i open an excel file. I've tried several things to no avail; Windows10 is not ready for me... I am uninstalling until this is fixed...

    Windows 10 Pro-64 Bit Build 10240

    Add me to the list.

    Excel and Word were running super smooth with < 0.5 second delay under Win 7 Ultimate 64 Bit, upgraded to Win 10 Pro, now double-clicking on any MS office file take 8-10 seconds. Tried disabling Cortana voice and Cortana altogether, neither worked. Tried using the Office disc for repair, that did not work.

    The only work around that works for me is to open Excel or Word first (no delay) then open the document, then there is no delay.
