“Why doesn’t my PC boot with more than 16GB of RAM?”

(Answer requested by “Weslo”) The three primary reasons for RAM limitations: There can be mathematical limitations: a 32-bit PC can only access about 4GB of RAM, because that — roughly 4 billion — is the highest you can count using 32 bits of data. A 32-bit operating system literally can’t “see” or access memory at…

“What percentage of people like the iPhone brand?”

(Answer requested via Quora) If you go by sales, the answer is about 10%, which is Apple’s current smartphone marketshare: (Apple fans tend not to believe stats like this, so here’s a pile of alternate sources: “smartphone market share” – (Google Search) Apple’s aggressive marketing makes most people think that Apple sales are far larger/better…

“How do I disable a laptop’s keyboard except for the power button?”

That could be problematic — how will you control the PC if none of the keys work? A better option is a software-moderated kiosk mode, which severely restricts what users can do with the PC while not preventing the PC from acting normally, outside of kiosk mode. Operating systems and browsers usually each support their…

“What was the most weird computer you have ever used?”

(Answer requested by Chris Fisher) Hmmm. Several come to mind. There were a series of early Soviet-era PC clones I saw in Russia and Hungary in the early 90’s, shortly before the USSR dissolved. Many of the computers were in the “close but no cigar” category, superficially emulating Western PCs (IBMs, Apples, Commodores, Ataris…), but…

“How many passwords do you keep for smartphones & laptops?”

(Answer requested by Byron Inductivo) I currently have over 700 passwords in use, but I only have to remember one. I use a password manager on all my devices: I only have to remember the password-manager’s own master password. Once I enter that, the software takes over. When I encounter a website or app login…

“In a PC with 8GB RAM, 16GB Optane memory, and 1TB HD, what is the benefit of the Optane memory?”

I recently purchased a similar Optane-equipped PC, benchmarked the hell out of it, and used it in real life — before ripping Optane out of the PC. I documented the results in these three articles: Part 1, “Taking the plunge with a new PC” (AskWoody Plus newsletter 2019-06-03), gets the ball rolling. In Part 2,…

“How can the defragmentation of a hard drive affect PC speed?”

(Answer requested by Ahmed Belkhouja) Very easily! Here’s why: Files are stored on a hard drive in very small chunks called clusters. On a conventional NTFS-formatted drive, for example, the default cluster size is 4KB; large files are stored as a series of 4KB clusters. On a new, empty, spinning-platter drive, saved files will be stored…

“Why do experts say that it is not advisable to install free antivirus software on a PC?”

Are your “experts” selling antivirus software, perhaps? The fact is: The price of a thing does not necessarily correspond to its overall quality or true value. For antivirus apps (free or paid), check the tests results posted by independent agencies such as AV-Test.org. You’ll see that several free apps are among the top-ranked tools. (Of…

“My laptop mouse/keyboard is not working in Windows7 after an update; but they still work fine in Safe Mode. What should I do?”

Sounds like driver trouble. Something in your regular Win7 drivers isn’t working with the new update; but when your PC falls back to generic drivers (as in Safe Mode), things apparently work OK again. Option 1) Go to your laptop maker’s support site; download (but don’t yet install) the correct Win7 drivers for your exact…
