I have a Pavilion dv7 with Windows 10 on it.
It is Sooooooooo slow to fully boot (182 seconds according to Trend Micro).
Win 10 Home v1511
OS Build 10586.104
Processor: Intel i7 Q720 @ 1.6Ghz
64-bit on x64-based processor
2xWDC WD7500KPVT 750Gb HDDs
Startup is showing:
Adobe Gamma Loader
Catalyst Control Center Launcher (x3)
Platinum user session agent (Trend Micro)
Synaptics Touchpad Enhancements (x4)
Trend Micro Client Session Agent Monitor.
Everything just takes heaps of time to open up.
For instance: In task manager, I just tried to "Open Resource Monitor" and it took about a minute to open with nothing but one spike about 25% CPU. Opening it again and it takes less than a second.
