Laura E. McDonald wants to know why her PC "does not recognize the hardwire connection."

If you've got working Wi-Fi and apparently dead ethernet, the first thing to do is turn off the Wi-Fi. Believe it or not, this might tell you that the ethernet is working. If Windows has access to both, it will give top priority to ethernet, but display the Wi-Fi icon in the notification area. There's likely a hardware switch on your PC for turning off Wi-Fi.

And even if that doesn't solve your problem, it will make the tests below easier to run. You'll see immediately if ethernet is working, which is exactly what you need to know.

After reading my article on stopping autoloading programs, Quietone asked “What programs are really needed during start up?”

Most Windows PCs autoload a ridiculous number of programs every time you boot. And as I explained in the previous article, disabling most of them could improve performance. The programs will still be there when you want them, but they wouldn’t be hanging around in RAM, using up resources, when they’re not needed.

But which autoloaders should you not disable? The easy answer is those that really do need to run all of the time to do their jobs. I can’t tell you exactly what they are, because I don’t know your work habits or your hardware. But I can give you a pretty good idea.

In its current Technical Preview edition, the next major version of Windows can send your keystrokes and spoken words to Microsoft. Andy Gorfman asked if it will stay that way. “Apart from taking Microsoft on trust, how do we know that [the spyware will be removed].”

Paranoia seems reasonable these days. We know that big-data companies such as Google, Facebook, and yes, Microsoft, gather information about us for commercial reasons. In addition to that, the NSA spies on us, and the big companies may be collaborating with them.

Meanwhile, the Windows 10 Technical Preview Privacy Statement is indeed a scary document. It informs us that “we may collect voice information” and “typed characters.” That’s not what you want in an operating system.

Siddhartha Raval asked how to take care of a laptop battery so that it lasts a long time.

Batteries don't last forever. Like everything except diamonds and viral tweets, they eventually wear out. But with proper care, a laptop battery can still carry a sufficient charge until you're ready to move on to a better laptop.

But it's a tradeoff. Taking the best care of your laptop battery just may be more of a hassle than it's worth.

You don’t have cellphone coverage—or affordable cellphone coverage—everywhere. That’s why Joel asked if he could download maps when he has Wi-Fi, and use them when he has no access to the Internet.

The Android version of Google Maps offers a way to download maps for later use, but it’s limited. In case it meets your needs, I’ll tell you about it. Then I’ll recommend a much more powerful app.

Hoping to speed up his PC, Elijah Kinch Spector (yes, we’re related) asked about adding more RAM.

The amount of Random Access Memory (RAM) in your PC may or may not be the machine’s major bottleneck. But it will likely speed things up, and it’s easier to install than an SSD, which requires you to move your operating system and other files.

But you have to know not only what kind of RAM your PC can take, but also how much of it.

Frank Hammond asked how to access the AppData folder and copy files from it.

The Application Data—or AppData—folder contains data created by programs. Almost every program you install creates its own folder in AppData and stores information there. At least in theory, users don’t have to worry about these files.

But in reality, you probably do. For instance, my personalized Microsoft Word templates and Sticky Notes file all reside inside AppData. If you’re using an older version of Outlook, that program’s data is probably in AppData, as well.
