AgentX20 Have you considered 8.1 instead?
I haven't noticed any issues when I've been on machines running it - afaik it is compatible with Win7 drivers so could be a option.
Also I would imagine many developers are going to drop Win7 support in the next year. Other companies are even more militant nowadays and insist on W10 installs.
The other issue i'm noticing is that latest versions of certain apps are causing strain. My advice, even just for backup purposes, make a note of what apps work for you and what version no's - and get them saved offline for future use.
