Windows 10: Windows 10 1909 sluggish after ~2 hours use on Word/Excel

First post. I've had an ongoing problem with Windows 10 for the last couple of years. Basically when using a second screen a Dell P2415Q on my laptop I found that the whole system become sluggish after a couple of hours. I assumed it was my Dell XPS 9560, and upgraded the memory, SSD and later the wireless card. Then I switched to my work laptop a Dell XPS 9370 and experienced the same lags.... so I changed monitor to a cheap Lenovo and no change.

As it seemed to be mostly keyboard lag, I ditched my Microsoft Surface keyboard and mouse and used a spare Pi wired keyboard - no change! As a last resort (as both my Dells were reconditioned), I just got a brand new HP Z2 mini G4 workstation with Quadro 1000 graphics (using both the Dell and Lenovo screen).... and it is still the same! So I am coming to the conclusion it is something with Windows 10, and I am fully up to date with patches and drivers etc.

My basic usage example is 2-3 Word documents open, 2-3 Excel documents open, 2-3 Adobe Acrobat Pro 17 documents open and Outlook. Sometimes I have Microsoft edge browser up, but I have noticed that during these sluggish periods it periodically crashes for no reason (this makes me wonder if there is some aggressive power management going on?). I'm on Windows 1909 and Office 365 home and to be honest have not installed much else at all since getting the new workstation.

The symptoms are:

• delay when focusing to a new window
• typing in Excel/Word many seconds delay before focus and then catches up
• edge browser just randomly crashes
• delay when scrolling or using arrow buttons
• closing windows (Word/Excel) delay
• various graphical glitches e.g. Outlook folder list is just grey and after many seconds the text shows up one line at a time (slowly)
• notifications do not come up when clicking taskbar icon
• get to point where clicking in cell does nothing in excel, then only a reboot will fix...

So, when I am away at work I am using some prehistoric Dell OptiPlex with absolutely no issues whatsoever. So this makes me wonder if it has something to do with OneDrive? I have tried to fully remove this, unlinked first then uninstalled but even after group policy edit it still lingers (on reboot the user/onedrive folder is back...)

It feels like a memory leak, but when I go to task manager there is plenty available and not any huge resource hogger. I'm at a loss now, and as has been said have seen this on multiple computers and changed just about everything hardware wise. That said, I have not resorted to running windows for best performance... because its an i7-9700 with Quadro card, so overkill for basic office tasks.

If someone can advise how to set up a log (or software to log) so that I can try and pin down what this is it would be much appreciated. I will endeavour to get some video grabs as well.

Word and Excel documents are slow to open in Windows 10

Have the same problem, here are my conditions:

- Windows 10 Professional x64.

- Office 2007 Ultimate.

- Opening Word and Excel documents is slow when Word/Excel not currently open/running.

- Opening the Word/Excel document with Word/Excel already open is fast/normal.

Solution is the same as reported:

1) Disable Cortana.

2) Restart Windows.

Step 2 is very important.

 

Word and Excel documents are slow to open in Windows 10

in my case, I don't need to restart windows. Closing cortana completely will make opening word and excel files fast like usual.
