In the past, like many I’ve experienced issues when upgrading to newer version of Microsoft operating systems. This experience goes way back. Please don’t ask how long.
Last week I listened to a friend whom I consider has reputable IT knowledge and skills. His view was don’t hang about, upgrade to Windows 10.
We’ve have four computers, two laptops running Windows 8.1, one desktop running Windows 7, and one laptop banished to the back of the cupboard running Windows XP. My experience is of trouble free upgrade to Windows 10 of one of our Windows 8.1 laptops yesterday evening. Perhaps less than two hours from start to finish. Hopefully, the remaining two upgrades will be as painless [not bothering with the XP machine].
