Now, before I get going, let me say that, despite these major issues I've had with my own PC. Windows 10 is actually a really good operation system.

Ever since I was able to upgrade for free, I've been running into a whole slew of problems. These problems are

• Sound Driver: My sound driver would literally stutter then die. The only way to fix this is to restart the PC.
• Video Driver: The source of so many Windows 10 Blue Screens of Death for me. Not to mention that Minecraft runs like absolute crap on Windows 10 for me, but runs smoothly on Windows 8.1.
• Wake Alarm: What's that? It's the driver that tells your PC to come out of sleep mode when you open your laptop, move your mouse, touch your keyboard, etc. it barely worked on my laptop under Windows 10. This would cause my hard drive to spin up then spin down, resulting in a rather gnarly crash and file corruption.
• Wireless Driver: Before upgrading, my wireless never had problems. But under Windows 10, I was frequently booted from my home network.
• Freezing: Under Windows 8.1, I've never had my OS lockup on me completely. Under Windows 10, however, my OS would frequently freeze and require a hard shutdown.
  

Now, keep in mind that my PC is rather new (it's not even two years old) and that, while I was running Windows 10, I had all of the latest Intel, Realtek, and HP drivers installed onto my computer and I was still having problems with Windows 10.

I heard that Microsoft is releasing their big Threshold 2 update in the first week of November. After it's released, I might (MIGHT) give Windows 10 another try.
