GDPR didn’t give you cookie banners, it’s shitty websites that do.

If they were to just follow activated “Do not Track”-Preferences, they wouldn’t need to ask, instead they would deactived them by default. Or you could just not use cookies, it’s not like somebody forces you to give cookies out to your website’s users.

I vaguelly remember around this time some low end computers were shipped with FreeDOS instead of Windows, in order to save on licencing fees. AFAIK this was the case because legislation in some european countries restricted the sale of new computers to ones which had an OS preinstalled.

Maybe XP was installed after the purchases however a partition with FreeDOS/whatever remained as the default boot option. Hence your parents had to select the other boot option (Windows XP) manually. Granted you could change your primary boot partition permanently, but maybe your parents didn’t know this.
