Solution: Mouse Cursor in Windows 7 Disappears

I reinstalled Windows 7 on my MSI Wind U123 today because of a number of problems with sound input and PulseAudio on Fedora 13 that I couldn't be buggered to fix. After the install, I ran Windows Update as normal, rebooted, and then noticed that my mouse cursor was gone. I could still click around and select things, so I knew the mouse was working, however I couldn't see it.

Searching Google proved worse than useless. The two best solutions listed were to either enable pointer tails (annoying) or lower the hardware acceleration level on your video card. Although true that both of these options will work, they both suck.

The real fix? Install the correct video drivers. As it turns out, when I ran Windows Update I accidentally selected the Intel Graphics driver update, which caused the problem. After downloading and installing the correct driver direct from Intel the cursor suddenly reappeared. Magic!

TL;DR Version: If your mouse cursor disappears, go to your video card manufacturer's website and get the drivers from them.

Short: Windows 7 Misreporting CPU Speed? Try This.

I noticed almost immediately after installing the first beta of Windows 7 that it wasn't reporting the correct speed of my processor. I'm currently running an Intel Core 2 Quad Q6600 (2.4Ghz) overclocked to 3Ghz. Oddly, Windows XP and Vista both reported the clock speed to be 3.00Ghz, but Windows 7 only reported 2.4Ghz. I made sure to verify that the overclock was still active with CPUID which confirmed that yes, the correct clock speed was 3Ghz. Several people suggested just re-running the Windows Experience Assessment, however that didn't do anything.

I'd mostly forgotten about the issue until I installed Rainmeter, and it started showing the stock clock speed as well. On a hunch, I went in to BIOS and, sure enough, Intel EIST (aka, SpeedStep) was enabled. After I disabled it and rebooted, Windows and Rainmeter immediately started showing the correct clock speed, 3.00Ghz.

Now why didn't I think of that sooner?
