“How can I hide the clock in the Windows 10 taskbar?”

(Answer requested by Rudy Triana) The setting’s a little buried, but the trick is to know that the clock is a system icon. If you search Windows for the specific phrase — system icon — you’ll find the setting. For example, you asked about Windows 10: Type system icon in the search box, and you’ll…

“A ‘Digital TV Tuner device registration application’ is slowing down my PC. Is there a way to remove it or fix it?”

Sure! It usually only takes a few clicks. That “TV tuner” app is usually leftover bit of a previous Win7 or 8 setup that was running the old Media Center add-on. Win10 doesn’t have (or need) a separate Media Center; those old software components do little now except cause upgrade problems. (Geeky aside: That “digital…

“Should I encrypt my computer hard drive?”

Depending on how you perform the encryption, yes. I don’t recommend whole-drive encryption because the encrypting is effectively part of the operating system. That is convenient, and can work great if the user is careful and knows what they’re doing. But it can lead to lockout issues even if the files themselves would otherwise be…

“Can a Mac and PC share a network hard drive?”

Sure! Although only one operating system can “own” the drive, it can share that same drive with one or more other OSes. Let’s say a Windows PC shares one of its drives to the local network; its permission can be adjusted as you like, but in general, any device on that network — Mac, Linux,…

“How do I run a batch file in Windows 10?”

Um, you click on it? I think you’re actually asking how to create and then run a batch file. That’s easy. It’s also pretty old-school, as Microsoft is pushing everyone towards the much-more-powerful, but much-more-complicated, PowerShell environment instead. But batch files still work fine In Windows 10; they’re still useful for quick task automation; and…

“I’ve installed a 1TB hard drive from my old PC. It has files but no operating system. How can I wipe it to use its full storage?”

You don’t need to wipe it. Simple re-partitioning and reformatting will make the drive fully available to you. And that’s a very good thing, because wiping a drive involves overwriting every spot on the disk — in your case, a trillion bytes’ worth. On an average system and HDD, that’d probably take something like two…

“Can I increase my RAM using a pen drive? Also, can I change the pen drive back after I am done?”

Not exactly. But if you’re using Windows, you can use a capable flash device to speed your system a different way: It’s called ReadyBoost, and it’s been built into the OS since the days of Vista. ReadyBoost lets your PC use a flash device as a predictive (“prefetch”) cache, preloading the data that the OS…

“How can you run Android phone apps on a Windows 10 computer?”

(Answer requested by Mark Austin) There actually are multiple ways to run Android on Windows, including the official emulator that’s part of Google’s free Android Studio. It’s excellent — Google is the de facto authority on all things Android — but it’s aimed at developers, and so might not be quite what you’re looking for….

“What is the Windows 10 paging file and why is it a good idea to regularly delete it?”

For most people, it’s NOT a good idea to delete the pagefile. A pagefile (or swapfile) is a temporary scratchpad area on the hard drive that an operating system (e.g. Windows) uses to store code and data when the operating system is juggling more stuff than will fit into RAM. A pagefile lets Windows act as…

“Did you like Windows 95 better or Windows 10?”

What a strange question! If you mean today, then Win10, hands down. Win95 was built for a different era, with different — simpler and much, much slower — standards. For example, PCs in 1995 typically came with 4-8 MB (not GB!) of RAM, a single-core 66MHz (not GHz) CPU, dial-up Internet connections, CD-ROM programming, and…
