I completed the hardware/software upgrade a little more than 60 hours ago.
Now running VWS 15p03 on Win 7 Ult 64 SP1 on a brand new ASUS Z97mPLUS motherboard with i5 4690K and 16 G ram.
WOW - it boots faster than the lightning it monitors!
The jump from VWS 12 to 15 had just a few bumps - mostly that I had to re-enter my station data and settings, but there hae been no VWS crashes or freezes thus far.
The two biggest problems: My CWOP reporting has become sporadic at best. Running VWSAPRS 1.9.7.0 set to automatic and ten minutes and running as administrator. But sometimes it reports every ten minutes and sometime it just says it has reported by CWOP says nothing for past hour.
Second MAJOR problem is that this fresh clean install of win7 refuses to connect to my win 2012 server essentials to be backed up! Useless Micro$$$$ suggests perhaps re installing the whole OS from scratch! RRRRIIIIGht!!! It's FIXED
Gotta love "user" forums - a guy expalined the same problem on a win 8.1 system and listed the easy fix to a single txt file on the server and viola! backing up at the speed of ssd's over gigabit!
I guess this is just what happens when you try to exceed the speed limit of light - space time - consider yourself torn!
