The wordpress administration page can be login by IE under Windows 7 only

Dear all


I get a problem to access my Wordpess administration page.


The page can be login by IE 11 under windows 7 only.


I tried Chrome, Firefox under windows 7, and MS Edge, IE 11, Chrome under Windows 10, all of them cannot login to the admin page.


It just remove the entered password to a blank field, no other warning message.


It is not created to cookie problem, I cleaned and even used a new PC to test it.


As the windows 7 will discontinue soon, any hints to solve the problem.


Thank you for your kind attention.
