TestComplete 14.10.1042.7 and Windows 10 performance


TestComplete 14.10.1042.7 and Windows 10 performance


The performance of certain operations is "extremely" slow when using TestComplete or if TestComplete is opened.  Example:

1. Open TC

2. Open tested application

3. Perform an operation via TestComplete (example: clicking an item in a menu)

4. Result: takes 60 seconds for operation to complete

5. Perform same operation manually

6. Results: takes 35 seconds

5. Close TC

6. Perform same operation

7. Results: takes 10 seconds


How can this performance issue be resolved?

This didn't occur on my Windows 7 laptop- only started happening on Windows 10 laptop.

I've unchecked the Windows Store Applications option.

I've checked all the Desktop install extensions.


Thanks in advanced!!!

Since you've moved TC to another computer, this may be of some help:

Marsha, thanks for the reply.  I double-checked and the settings are correct.


Check the Windows Updates section here.  There are some Win 10 performance issues listed:

I gave that a try and it didn't improve the performance.



I suggest that you contact Support directly with your question.  Here's the link:

One of the big things to change is under Tools | Options | Engines | General -> Turn off the option for Windows Store Applications and restart TestComplete.  That might help.

Why automate?  I do automated testing because there's only so much a human being can do and remain healthy.  Sleep is a requirement.  So, while people sleep, automation that I create does what I've described above in order to make sure that nothing gets past the final defense of the testing group.
I love good food, good books, good friends, and good fun.

Hi Robert,

Thanks for the suggestion.  I already unchecked that option.

I'm also running TestComplete as admin.
