Something I've been wondering since MS claimed 10 would be their 'last' OS, which I take to mean rolling updates, is what will happen with regards to OS bloating?
Every Windows OS so far has gained bloat over time with updates, service packs, etc and 'upgrading' to a new OS often meant shedding all of that bloat and ending up with a smaller, tidier OS. At least to start with.
For instance, XP on release ran reasonably well on a system with 128MB RAM and a 1.5GHz Northwood Celeron (I had one). But XP in its latest form is horribly bloated and slow on the very same system. The same applies in varying degrees to newer OS's too, Win7 has grown significantly over time; however the option for Windows Update cleanup in Disk Cleanup helps alleviate the disk space impact somewhat.
My point being you can install an OS clean on a system and it runs fairly smoothly, but let it churn through Win Update until completion and performance can take a huge hit.
Off topic a bit but it's not just Windows by any means - Android on my old Galaxy Ace seems fairly responsive after a factory reset. But let it update Play Services etc in the background and it slows down considerably.
Also I'm not sure if it's more to do with Windows or the notoriously RAM-hungry Chrome (I'm worried if Firefox going multi-process means it going the same way too ), but 8GB used to be more than enough for a ton of Chrome tabs, an XP VM in VirtualBox, Firefox, Thunderbird, Skype but recently I'm seeing a fair amount of memory warnings (I know why, I deliberately have paging disabled, it's just an observation). Heck, even 4GB used to be enough if I laid off on the VMs.
Anyway I digress - my question is, how will the 'last' Windows combat this seemingly inevitable OS bloat? Of course the 'last OS' thing could be a bit of a misnomer and they're going more like Android/iOS/OSX which do still have full versions, but have them 'free' rather than charging for the OS? It's just one of the many things about Win10 which still isn't clear. If it really is free upgrades, would that imply that system builders such as many of us wouldn't need to fork out for future releases any more?
The whole 'last OS' thing seems a bit final and raises a load of questions. And I really don't like the thought of waking up to find Win10 has auto-updated and pulled a stunt like the Win8 Start thing with no real way of deciding to skip it. I didn't like Win8 and I had the option to stick with 7, which I did. The unanswered questions along these lines, along with the complete lack of clarity on licensing, privacy issues etc are all making me postpone moving to Win10.
