I was Advised to stuck with 7 untill 8 becomes mire stable.
Urban myth?
Hmm, not unwise to wait a while to see what falls off 8. However, the difference here is that 8 is a step on from 7 which is stable. It was true that Vista was a pig of an OS and one was wise to wait until at least SP1. However, Vista was quickly made the devil and suddenly a much-improved 7 appeared 3 years later. Call me cynical but MS increased the internal version of Vista to 6 (XP and Windows Server 2003 are 5.1) and changed it massively. They had to - XP is shocking on security in comparison. Once all the developers had got everything working on that sh***er Vista (internal V6 - see above), suddenly everything worked fine on 7 as a result! Quel surprise. Saying that, some stuff that I tested didn't work on Vista and does work in 7 - so they must have brought back some compatiblity from XP (XP emulation excepted).
I'm in need of a new desktop but one of the programs I use and depend on is an 8 year old Sage Line 50 and I don't know if it'll run on Windows 8. It's an expensive program and I ain't happy about buying a new one
If it works on Vista or 7, it's very likely it will work on 8. If you are running it on XP, whilst you can look it up (there's bound to be other articles on it) to find out if it is compatible (not certified or not supported doesn't mean it wont run - just Sage wont support it, assuming they do now).
Failing that, you can run it in 'compatiblity mode' but I've not had much success with that.
If not, you can run XP emulation - but this is a little bit 'JCB to crack a nut'. Typically, the Home versions can't do this so you need to buy Pro or Ultimate - may not be worth it.
If not, upgrade. If too expensive, can you run it on a second older computer just running XP and nothing else?
