Maybe you had an email about Win7 EOL but as I opted out of the MS 'Customer Experience' telemetry gathering options I did not.
However I've been, like most Win7 users should have been, aware of the EOL date for years.
It is what, exactly, is and is not going to work after that date, in particular MSE that is of concern.
When they pulled MSE support for MSE on WinXP I was using it on a VM (Virtual Machine) the only purpose MSE is ideally suited too. It has a small footprint, won't conflict with the parent PC's AV or other security software and does a good enough protection job for if you just limit your browser/online use to the minimum. Perfect for WinXP on a VM after its EOL.
Unfortunately they did not recognise this continued usefulness so when, without warning, MS killed MSE with WinXP an alternative had to be found. I've not been happy with either of the solutions I've tried (AVAST and another lesser known AV) as both significantly slows down the VM (it uses a paltry max 1GB of dedicated RAM), particularly on boot. Both 'solutions' also added a far bigger footprint too which, when you're using a relatively small SDD, adds to the problems.
TBH I do not want to go through that again with Win7. But we might not get any choice if MS decide to be 'unhelpful'.
