I installed windows 10 for free on my notebook with the windows 10 Upgrader, everything worked fine
on my desktop it does not work, Kaspersky says it is malware
I also had Kaspersky on the notebook
Should I temporarily turn off Kaspersky Protection on Desktop?
does anyone have an alternative as I can upgrade from windows 7 to windows 10 for free on desktop?
Windows 10 is in my opinion anyway garbage.
Simply disable Kaspersky for the duration of the installation. If you have obtained all installation media from Microsoft, there's no danger.
Kaspersky
You answered your question yourself.
In addition, Kaspersky is unnecessary. Windows Defender is enough.
And what would be the alternative?
I've been out of habit for many years Kaspersky, why do you think windows Defender is enough?
What do you mean exactly when you have all windows installation media related? I only know the pc is from my ex and I have no idea which installation media she got from where and when
Get the Windows 10 Update Assistant from Microsoft. He can do that.
Because it's neither better nor worse than other programs and components of Windows.
It would be great if Microsoft continued to do Windows 7, otherwise Windows 8, or Windows 8.1
