In reply to stp:
I finally got my new works laptop (an engineering spec zbook). Unlike the rest of the dept who’s were ordered before Xmas and came with Windoze7 mine has W10, not a happy bunny – got deadlines to meet so don’t need the hassle of a new OS.
All the packages we need are stored on our server and have been used multiple times with W7 machines. Installing them on my W10 machine has killed it (unhandled thread problem on boot – so it’s off back to IT for a reinstall and a wasted 3 days) proving the exception to the statement that most W7 applications will run on W10. The main package I use is OrCAD which is quite a flaky house of cards at the best of times so spent quite some time talking to our support contacts but got 95% of the way there before it died. So have spent quite some time digging into the unfamiliar intricacies of W10 (where the hell is the Control Panel shortcut and why does entering “control” into the search bar usually result in no entries, although the upgrade to Data Source Administrator is certainly a step forward).
Can't comment on the long term W7 security aspect. I have a damn good firewall as part of my router and have never had a problem with any of my minimally protected 'always on' machines and can't see this changing even if W7 stops getting updated. I even have an old XP machine on my network, for running legacy software which has never had a problem (yes I check the router logs, so I would know if they misbehaved).
Verdict: Still don’t like it and would prefer W7, but eventually all our corporate machines will be W10 so will have to get used to it sooner or later. I can’t see any advantage to upgrading my own personal machines at this time (and probably for at least the next few years). But with the Classic Shell at least it isn’t totally alien but the differences are still annoying.
