I installed Windows 10 a week ago and everything seemed to be fine. However, 2 days later, Windows Live Mail became inaccessible. The timing circle spun round and round and, eventually - after 10 minutes or more, the following notice was displayed. Windows Live Mail could not be started. It may not be installed correctly. Make sure that your disc is not full or that you are out of memory. (0x80041161) 

After  a 2-hour visit by my local computer repairer man, everything seemed to work OK again (except that e-mails put into the Draft file immediately froze and I couldn't recover them to work on them again.

2 days later (this afternoon), Windows Live Mail became inaccessible again, the same timing circle spinning and the same notice about memory appeared.

My computer repairer man is on his way to fix the problem - AGAIN - but I have little hope that he will resolve the problem.

I am regretting downloading Windows 10.

How is it that a program (Windows Live Mail) that is supposed to be compatible with Windows 10 fails so miserably?

How is it that trouble-shooting the problem(s) is so difficult?

What a failure by Microsoft!

Should I change to Apple?

Give me an escape from my misery - PLEASE!
