Windows 10: Excel files open very slowly

I don't think you can disable it.

 

I think not, I also found out it can't be uninstalled from Windows 10.

 

Reading old solutions for slow excel, before windows 10, seems like it was related to the Intranet traffic setting inside Internet Explorer.
I searched for the same settings inside edge options (edge has got poor options settings) and I can't find any.
Now I've found this:

Available policies for Microsoft Edge (Windows)

Maybe that sending intranet traffic to IE11 will do the trick. I someone can test this now let me know.

 

I see the problem when opening the file first, as opposed to opening Excel first. This really doesn't apply to me as I almost always open Excel first, and then look in my recent history. In this case, the application and files open quickly.


However, I can reproduce what the OP found. There is probably about a 7 second delay opening files individually. I tried the group policy setting above and rebooted. Unfortunately, it was unable to find any wireless connection - I was unable to connect to the internet. So I changed it back.

 

Ok, but before reverting back, did you try to open an excel file?

 

Yes, there was no change. Sorry, I should have made that clear.

 

I just came from work and I found out that after waking up the computer (it was in sleep mode while I was at work), Excel problem disappeared. I'll see what happens after few hours of usage...

 

I just created another account on the pc, excel worked. I started edge, excel still works. I will try to explore other solutions before doing as you did.

Would you mind briefly explaining how you connected local account to online? Does it have to be new online account or can I use my standard one?

Thanks.

 

Maybe related to online profile... onedrive integration? Who knows...

 

I used my standard MS Account (which I also used for my first account on Windows 10 and on Windows 8.1), I connected it using standard MS options found in Settings / Accounts.

 

It seems I am on to something - problem seems to be caused by modified HOSTS file I installed few days ago to block ads in Edge. For some reason, it can be reproduced by visiting a page containing (blocked) ads and it doesn't go away after exiting Edge because parts of the browser remain in memory. Problem disappeared after I ran CCleaner, which asked me to "exit Edge" (although it was already closed) and it will appear again if I visit a page full of ads. So, the solution seems to be to use the default HOSTS file and wait for Edge extension support to block ads.

 

I don't think so. I have no modified host file.

 

I am afraid it is different root cause for everyone.

 

In my case, this was the solution, and I think this might be somehow related to the intranet problem GDT mentioned earlier.

 

I just ran cc cleaner for registry to be sure, didn't help.
