1. About  "xmr-stack style": we're naming it Claymore style.
The reason we need it is that we're having many rigs (100+), and for upgrade old Claymore 3.9/4.0 into new your or another one, better just change some files w/o changing somethins in working machines.
On some pc's cn miner works as service through nssm (non-sucking service manager) or through some another.
And in all of that machines and rigs we're just having exe file in startup or in services.

2. Why win7 is not supported? On old pc we have winXP, it's ok, they are old and can mine only 20-60 h/s. Nobody have win8... some have win10... But the most other PCs are running Win7! Why not? Nobody have win8... a little have win10...

3. Found little bug.
