Please make sure that you update Windows to the latest version, 14393.447.
Please remove / disable items from the startup in taskmanager
These programs could interfere with the boot process giving you trouble and increase the boot time.
It appears you have some rogue software installed, Solvusoft programs for example, are they installed intentionally?
The root cause looks to be a driver from Juniper, I would suggest to update/reinstall/remove the software.

If you have installed any driver with these programs, please remove them as it may cause trouble.
An easy way to get remove these drivers is by using a restore point prior the installation.
