Microsoft, Please Stop Breaking My PC With Windows 10’s Automatic Updates

Hey Microsoft, could you please stop breaking my PC? The latest WPD driver update released on March 8, 2017 is just the latest in a long string of bad updates. If Windows 10 is going to force these updates on my system, the least Microsoft could do is test them properly first.

Don’t get us wrong: automatic updates are very important for security reasons, and we believe they are a good thing. The problem is that Microsoft isn’t just releasing security updates. They’re making major changes to Windows, and not testing the updates properly. They need to do better.

Microsoft Just Released a Bad Driver Update, and I Have to Fix It

The latest and most obnoxious update—at least for me, personally—was the “Microsoft – WPD – 2/22/2016 12:00:00 AM – 5.2.5326.4762” update released on March 8, 2017.

Microsoft removed this update from Windows Update, but not until after my and other PCs installed it. As a Microsoft representative explained in a discussion post on Microsoft’s community forums:

“An incorrect device driver was released for Windows 10, on March 8, 2017, that affected a small group of users with connected phones or portable devices. After installation, these devices are not detected properly by Windows 10”

That’s right: Microsoft released a bad driver update that broke the MTP drivers in Windows. MTP is used to access files on connected Android phones and tablets, media players, Windows phones, and some other types of portable devices.

This update seems broken for everyone, so how did it get onto Windows Update in the first place? Driver updates are supposed to be tested through the Windows Hardware Quality Labs before they’re allowed onto Windows Update. Apparently that isn’t happening properly.

Microsoft caught the problem, so that should be the end of the story, right? Nope. Microsoft isn’t going to release an automatic fix through Windows Update to correct the problem. It’s my job to fix what Microsoft broke on my PC, and it’s your job to fix it on your PC if Windows 10 automatically installed the same update for you.

As this is a driver update, there’s no way to “uninstall” it like you would a normal update. Instead, Microsoft recommends you use a system restore point, something that won’t be possible on many PCs, as Windows 10 seems to sometimes ship with System Restore disabled. If you can’t do that, Microsoft invites you to follow a 13-step process involving the Device Manager and several commands run in an Administrator Command Prompt window.

That’s absurd. Worse yet,…

How to Maximize Your Linux Laptop’s Battery Life

Laptop manufacturers spend a lot of time tuning their device drivers for Windows battery life. Linux usually doesn’t get the same attention. Linux may perform just as well as Windows on the same hardware, but it won’t necessarily have as much battery life.

Linux’s battery usage has improved dramatically over the years. The Linux kernel has gotten better, and Linux distributions automatically adjust many settings when you’re using a laptop. But you can still do some things to improve your battery life.

Basic Battery-Saving Tips

Before you do anything too complex, adjust the same settings you would on a Windows laptop or MacBook to maximize battery life.

For example, tell your Linux laptop to suspend—this is what Linux calls sleep mode—more quickly when you’re not using it. You’ll find this option in your Linux desktop’s settings. For example, head to System Settings > Power on an Ubuntu desktop.

Screen brightness can affect battery life dramatically. The brighter your display backlight, the worse your battery life will be. If your laptop has hotkeys to change screen brightness, try them—they’ll hopefully work on Linux, too. If not, you’ll find this option somewhere in your Linux desktop’s settings. It’s available at System Settings > Brightness & Lock on Ubuntu.

You can also tell your Linux desktop to turn off the screen more quickly when it’s inactive. The laptop will use less power when its screen is off. Don’t use a screensaver, as those just waste power by making your computer do more work and leaving the display on.

You can also disable hardware radios you don’t use. For example, if you don’t use Bluetooth, you can disable it to gain some more battery life. Head to System Settings > Bluetooth to disable Bluetooth on an Ubuntu desktop.

If you’re not using Wi-Fi, you can save a bit of power by disabling that, too. On Ubuntu, head to System Settings > Network and enable “Airplane Mode” to disable Wi-Fi and other wireless radios.

Remember that what you do with the laptop is also important. Running heavier software and using more CPU resources will cause your laptop to use more battery power. For this reason, you may want to look at a more lightweight desktop environment, such as the Lxde-based Lubuntu instead of the Unity-based main Ubuntu desktop.

Install Proprietary Graphics Drivers (If You Need Them)

If your laptop has integrated Intel graphics, congratulations. You shouldn’t need to worry about power management issues with your graphics drivers. Intel graphics aren’t the fastest, but they have excellent open-source driver support and “just work” out of the box.

If your laptop has NVIDIA or AMD graphics, however, you may need to do some work to decrease power consumption.

The worst case scenario is a laptop with NVIDIA Optimus or AMD’s switchable graphics. Such laptops have two different GPUs. For example, an NVIDIA Optimus laptop will have both a more powerful, battery-draining NVIDIA GPU and a less powerful, battery-friendly Intel GPU. On…
