I don't normally get this het up about software and I don't normally say it out loud but it must be said - Windows 10 is a crock of sh1t. The poor interface on top of just another NT6 with no real improvements to the core o/s but instead just major changes to the GUI whilst adding a load more inconsistencies/bugs is really not good enough. Win 7 was really the last good o/s that has come out of Microdolts.
On top of the games that no longer work (that I mentioned in an earlier post), so much in Win10 is tatty and unfinished, it is difficult to theme properly and it keeps generating fundamental errors that make it unusable for enterprise level software. There is this thing called WMI which is the Windows Management Instrumentation layer that is mean to provide system level information in a standard fashion to allow monitoring programs access. This is vital stuff for businesses to test their PCs/servers are functioning correctly. In Win10 it either does not work, is corrupted or just stops working for no apparent reason. WMI is one of those fundamental building blocks that HAS to work in order for Win10 to be seen as a decent and grown-up o/s. It worked well enough in XP, Vista, Win 7 and 8 but not in 10.
When WMI fails it breaks all sorts of vital enterprise level monitoring software that uses it. WMI is just not working or configured correctly in some configurations, no rhyme nor reason...
Recent updates to Win10 have broken other things like GDI font rendering, breaking any utility that uses pretty GDI fonts - Rocketdock, Objectdock and Winstep Extreme have all been affected, if only temporarily. These and other sorts of errors show that Windows 10 is flaky and should be avoided if at all possible until it is fixed. Rule 1: Don't install a new o/s, what you always need is the stable old o/s not the new. I wish I'd followed my own advice. So far my experience of using Win10 is like using a new car where 50% of the bolts haven't been properly tightened yet - you don't know what is going to fall off next. Lots of people complaining about it, including me.
Having said all this, I am using Windows 10 daily and for ordinary use it is bearable. Mine is heavily customised to remove most of the new metro tiled interface and to replace the massive metro menu. I have also replaced the task manager with that from Windows 7. The majority of Windows applications (not games) work out of the box - so, for most people Windows 10 is good enough - as it works. However, some of the advanced functions are buggy and that is where I am working. My biggest grief is the interface, the bugs and the absence of some DRM support.
When I open my old XP laptop I see what a great o/s it was in comparison, the interface is consistent and designed for a desktop PC, no feely, touchy-crap for tablets, everything works and it is lovely. I am stuck with Win10 on my new lappie and I have persisted with it but I am starting to hate it.
So with this in mind I can only suggest that you continue to use the last stable o/s from Microsoft, not Vista which screwed up XP, not Windows 8, nor 8.1 both of which broke the Windows desktop interface, not Win10 which is just again attempting to fix those GUI things already broken (whilst introducing new bugs) - the last stable and usable o/s from Microsoft really was Windows 7. Note: Between them, Win7 and XP still have 60% of the installed user base. Currently, Windows 10 has only 10% of the market.
Personally, I can only pray for ReactOS! An O/S that will run win32 programs and drivers without MS MicroShafting us with an unfinished GUI every year or so.
