Dangerous root certificates are a serious problem. From Lenovo’s Superfish to Dell’s eDellRoot and a number of other certificates installed by adware programs, your computer’s manufacturer or a program you installed may have added a certificate that opens you to attack. Here’s how to check if your certificates are clean.
For whatever reason, sooner or later we all have someone or something mess around with our keyboards and create ‘interesting’ results. With that in mind, today’s SuperUser Q&A post has a simple and elegant way to help a frustrated reader restore his desktop icon text back to the default appearance.
With Windows 10, Microsoft seems to have disabled System Restore by default — at least on some PCs. System Restore has been around since Windows ME, creating snapshots of system files you can restore if a problem occurs.
BitLocker disk encryption normally requires a TPM on Windows. Microsoft’s EFS encryption can never use a TPM. The new “device encryption” feature on Windows 10 and 8.1 also requires a modern TPM, which is why it’s only enabled on new hardware. But what is a TPM?
Tell your file manager to show hidden files and you’ll see quite a few junk files scattered across your folders. Windows creates thumbs.db and desktop.ini files in many folders, and Mac OS X creates .DS_Store files.
Each network-connected device — laptops, desktops, smartphones, tablets, and everything else — has an IP address on the network and a unique MAC address. There are many reasons you might need to find this information, so here’s how to find it on all the laptops, smartphones, and tablets you might have lying around.
If you’re dual-booting Linux alongside Windows 10, 8, or 8.1 and you want to mount your Windows system partition and access its files, you’ll run into a problem. You’ll see an error saying “The NTFS partition is hibernated” due to the new hybrid boot feature, preventing you from accessing its files.
Windows 10, 8.1, 8, and 7 all include BitLocker drive encryption, but that’s not the only encryption solution they offer. Windows also includes an encryption method named the “encrypting file system”, or EFS. Here’s how it differs from BitLocker.
The paperless office isn’t yet here for many of us, and printers are still a fact of life. If your printer isn’t working quite right on a Windows PC, here are some simple troubleshooting tips that can fix it.
It’s a good idea to give each of the devices you use a meaningful name. This is especially important on Windows 10, as Microsoft has removed the computer name option from the first-time setup process. Windows 10 PCs will just receive random, meaningless names by default.
Steam’s Music Player allows you to add a MP3 file stored on your computer to a local music library and play it back — inside or outside a game, with a controller or keyboard and mouse. This would be particularly useful on a Steam Machine or living-room gaming PC in Big Picture Mode.
All operating systems require a certain amount of disk space in order to run and function properly, so how are ‘economy model’ laptops able to properly function with the small drives that are built into them? Today’s SuperUser Q&A post has the answer to a curious reader’s question.
Microsoft has hidden the build number in an attempt to make Windows 10 look always-up-to-date, and there are still different editions of Windows 10 with different features. Microsoft is also still offering both 64-bit and 32-bit versions of Windows 10, too.
Modern desktop operating systems like Windows and Mac OS X offer built-in tools for calibrating your display‘s brightness, contrast, gamma, and color levels. This can help make text more readable and give images and videos more accurate colors.
If you’re a long-time Windows user, you’re probably familiar with service packs, but Microsoft seems done with them. Windows 10’s first big update — the “November update” — is a “build” rather than a service pack. Windows 10’s future big updates will be builds, too.
If your USB flash drive, SD card, or another drive isn’t working quite right, “cleaning” the drive and removing its partitions is one possible solution. This can fix problems with a drive that can’t be formatted or one that shows the wrong capacity.
Windows 10 doesn’t just automatically collect information about your computer usage. It does do that, but it may also pop up from time to time and ask for feedback. Here’s how to disable any Windows Feedback pop-up notifications you may see.
While most of us probably give little thought to all that is happening each time we shut our computers down, what is actually going on ‘under the hood’ during the shutdown process? Today’s SuperUser Q&A post has the answers to a curious reader’s question.
Whether you’re formatting an internal drive, external drive, USB flash drive, or SD card, Windows will give you the choice of NTFS, FAT32, and exFAT. The Format dialog in Windows doesn’t explain the difference, so we will.
If you are someone who loves using the Windows Command Prompt, you may have found yourself curious as to why the screen output buffer has such a ‘large’ default size. Can you change it to a smaller (or even larger) size? Today’s SuperUser Q&A post has the answers.
Windows 10 automatically installs updates in the background. The only way to prevent them from being installed is to set your connection as metered so they don’t download automatically. But updates — especially major new builds of Windows 10 like the November update — could potentially cause problems.
Modern laptop and desktop keyboards have a multi-purpose set of keys in the “function” row. These keys can perform special actions related to the audio volume, playback, and hardware features. They can also function as the classic F1-F12 keys — but not at the same time.
Some manufacturers ship PCs with their internal drives divided into multiple partitions — one for the Windows operating system, and an empty “data” partition for your personal files. You can combine these partitions into a single one, if you prefer.
Whether you’re letting go of a computer or disposing of a USB drive, it’s a good idea to wipe that drive if there was ever sensitive, unencrypted data on it. This will prevent someone from using deleted-file-recovery tools to recover sensitive data from that drive.
All modern computers, smartphones, and tablets can now easily print web pages and other documents to PDF files without any extra software. Microsoft added this to Windows 10, and Apple added it to iOS 9.
