Recently I installed Windows 7 Professional N 64-bit, from Windows 8.1 64-bit. Everything worked fine the first couple of days of using Windows 7, but then I started having trouble with some devices not being installed properly, it does recognize the device, but when I look in the device manager I can see a yellow/black triangle next to the device, when I right click it tells me to troubleshoot the device, it then starts to find and install drivers for it, but without success. And then it goes like that each time I re-connect the devices.
I have tried alot of things to fix it but none of them worked. Updating OS, updating motherboard drivers ( including USB controller drivers ). Switching USB ports. Uninstall and install the devices on to the PC. Remove drivers, restart and install again. Removing INFCACHE.1 from System32/driverstore. Install device drivers manually. And all of these attempts lead me back to the same thing.
The only possible problem as I see it right now is that the devices in question are in conflict with some recent update I made to Windows 7, as the devices worked fine as I had just installed Windows 7, but after the updates...no luck. Is there some way to "roll back" the updates without loosing everything stored on the PC?
I also attached a picture so you can see what is looks like.
