A client had started a time consuming process before leaving the office, came back the following morning with the process having failed due to windows applying updates and rebooting killing the process and losing a day worth of work.
YMMV.
I don't know what you mean by "this has to be done", there is no obligation to apply updates. What if I want my computer to run a windows without updates ? Am I not entitled to use my own property as I so choose ?
