get Microsoft Windows 10 upgrade problems for Free?

One of regular customers, a devoted Windows user, was tempted to upgrade from Windows 7 to windows 10 for free, who could blame him?
Following the link from official Microsoft email on windows 10 release date, and after some time the downloading and installation process … lost access to his computer.
Here’s problems he encountered.

Windows 10 upgrade lost all passwords included Windows 7 password to access actual windows. Other wiped passwords are Windows Live Mail and Skype. Only Firefox passwords for websites left intact. Icons no longer recognizable eg I could not find Programs and Features in Control Panel because it looks completely different. Apart of losing passwords Windows 10 disabled antivirus Bitdefender. So after recovering Windows password Manly Electronics had to reinstall antivirus from scratch!

Windows 10 is still missing the familiar and Windows Start menu. So you will have to use Windows Search each time to enable previously installed programs. The question begs, “what happens if you cannot remember what program you have?” This may, and I guess this is how Windows will become bloated with some redundant programs you’ve forget existed.
Apart of losing passwords and Start Menu and changing task bar to a creepy black bar we did not note any ‘improvement’ in Windows 10, included advertised speed, resembling Windows 7.

Other issues reported caused by Windows 10 upgrade:
Automatic Updates can get stack in endless loop. A registry tweak required to fix that.
A buggy graphics driver can be forcibly installed causing crashes.
A WiFi driver can be forcibly installed and WiFi connection can be lost, that particular one can happens because of third party network drivers such as work or business VPN drivers been installed on Windows 7.

The wash up, the Free Windows upgrade cost the user a couple of hundred dollars. So if you really want to support struggling global IT industry, please do upgrade to Windows 10! Our client expected a simple process, at the press of a button, at no cost, unfortunately this was not the case.
