I have worked in IT since 1974, sadly having to retire at the end of Aug 2006 due to bad health. I was the IT Manager of a small but busy IT department from Marchy 1989 to retirement.
I still miss the buzz, but sadly my brain cells don't always copy with my home computers never mind in a business environment.
I have recently upgrade my computers to Windows 10 (two notebooks with Windows 7 Home Premium, one desktop with Windows 7 Home Premium and one desktop with Window 8.1 Pro).
I have had various problems and finally decided to do clean install on all my computers and at last I can move forwards or so I thought unitil the last major update of Windows 10 by Microsoft and I am already beginning to notice things that worked before have stopped working, such as "Homegroups", early days yet, I wonder what else no longer works.
