That isn't what it looks like to me. If updating Windows had affected 
Tkinter, IDLE would no longer work and there would be thousands of 
people affected. I see no sign that this is the case:

It would be very, very suprising if you were the only person who has 
noticed that a Windows update broke Tkinter.

Mohamed, you said that you had done an investigation which showed memory 
corruption. What is your evidence for memory corruption?

So far there is no evidence for a bug in Tkinter or Python. This is not 
a help desk. There are many forums where you can get help debugging your 
program, you should create a minimal example and ask for help at

https://www.reddit.com/r/learnpython/

http://mail.python.org/mailman/listinfo/python-list

news:comp.lang.python

https://discuss.python.org/c/users/7

https://www.python.org/community/irc/

No matter which forum you go to, you will be asked for a minimal example 
demonstrating the problem:

https://medium.com/swlh/how-to-ask-smart-questions-d02f053a02ac

http://www.catb.org/esr/faqs/smart-questions.html

Note that a minimal program **MUST** be runnable. There is no point just 
deleting lines of code and replacing them with "...", because the code 
won't run.
