I was offered to reserve a free upgrade my Windows from 7 to 10 a few months ago and it was done with a Windows upgrade a month ago. However, a few problems are found after the upgrade:-
(1) Delay in typing and response: After I type 7-8 characters, there is a delay in typing and response. If I type fast, some key strokes are gone and they are not displayed on the screen so I need to type the words again. It is very frustrating
as if all my keystrokes are being captured causing delay.
(2) Installation error of Windows 10: After the upgrade, I could not find the "Internet Explorer" but "Microsoft Edge" which is not properly upgraded or installed. Every time I clicked on the icon, the "Explorer.exe"
error message is popped up. As I installed "Chrome" in my previous Windows 7, I use Chrome for internet access. Then I found "Internet Explorer" from the search menu and open it as administrator before I can use it. I
would like to know if the installation problems can be fixed by "Windows Upgrade" but I cannot find it as well.
(3) Restoration of Windows 7: I tried to restore my windows back to 7 but I was not prompted to make a backup before the installation of Windows 10. It seems like there is no way back now. This free upgrade is quite time-consuming and troublesome.
If I can switch backwards, I hope that there is a free downgrade.
Are all the above problems being caused by the size of Windows 10? I assume that it should be larger than Windows 7 in size and together with the memory size causing delay of 1-2 seconds even in typing every 6-7 characters (NOT words).
