“Can Keyboard Sound Expose Passwords? Experts Say No”:

See the Infopackets article by John Lister on August, 20 2019 at 09:08AM EDT.

Researchers say there's a risk that microphones and motion sensors in smartphones could make it possible to figure out information being typed on nearby keyboards. But media headlines that "hackers can work out your password" are a significant stretch.

The research comes from the Darwin Deason Institute for Cyber Security at Southern Methodist University, based in Texas. It stemmed from the thought that smartphones could pick up sound in two ways: not just the sound waves in the air through the microphone, but vibrations such as on a table collected through the motion sensors in the phone.

The testing explored whether these two sources of information would be enough to measure the different noises and vibrations caused by a user typing different keys on a keyboard. In particular, the researchers wanted to see if the use of the vibration and motion sensors would be enough to overcome the "interference" of surrounding conversations that would make relying on the sound waves in the air too difficult.

Tabletop Treachery

In the test, participants were asked to sit at laptops, engage in conversation with others in the room, and type notes of the conversation. This was designed to produce both the necessary typing and unpredictable content to try to detect. A series of mobile phones was placed on each table at varying distances to capture the sounds and vibrations.

The press release for the research says that when asking if it was possible to use this data to figure out what people were typing, "The answer was a definite 'Yes.'" (Source: smu.edu)

A Material Problem

However, the results showed this was far from a total success.

In fact, when it came to figuring out an individual keystroke, the success rate was only 41 percent. When trying to figure out an entire word, that fell to 27 percent. That means it's extremely unlikely an attacker using this method would be able to get a password, which would require every character to be correct unless it's a simple and obvious word. (Source: acm.org)

The big problem was that though the concept was valid, there was too much variation between different set-ups. That means that using the method would likely only be successful if the would-be attacker had advance knowledge both of the specific type of keyboard the victim was using and the material of the surface (such as a metal or wooden tabletop) that the keyboard and phone were placed on.

“Repair Install Windows 10 with an In-place Upgrade”:

See the TenForums article by Shawn Brink | Category: Installation & Upgrade 25 Jul 2019

How to Do a Repair Install of Windows 10 with an In-place Upgrade

If you're having problems with Windows 10 on your PC, you could use push-button reset to refresh or reset Windows.

Refresh your PC fixes software problems by reinstalling the OS while preserving the user data, user accounts, and important settings. All other preinstalled customizations are restored to their factory state. In Windows 10, this feature no longer preserves user-acquired Windows apps.

Reset your PC prepares the PC for recycling or for transfer of ownership by reinstalling the OS, removing all user accounts and contents (e.g. data, Classic Windows applications, and Universal Windows apps), and restoring preinstalled customizations to their factory state.

The options above are great for what they are intended for, but you could also do a repair install of Windows 10 by performing an in-place upgrade without losing anything other than all installed Windows Updates.

  • You will only be able to do a repair install of Windows 10 from within Windows 10. You will not be able to do a repair install at boot or in Safe Mode.
  • You will need at least around 8.87 GB + what Windows is currently using of free space available on the Windows drive.
  • The installation media (ex: ISO or USB) must be the same edition and same or newer build as your currently installed Windows 10. If it's not, then the repair install will fail.
  • The installation media (ex: ISO or USB) must be the same language as your currently installed Windows 10. If it's not, then you will not keep anything.
  • If you have a 32-bit Windows 10, then you must use a 32-bit ISO or USB. If you have a 64-bit Windows 10, then you must use a 64-bit ISO or USB.

If Windows is encrypted by BitLocker, then you will need to either suspend or turn off BitLocker for the Windows drive before doing a repair install. Once installation has finished, you can resume or turn on BitLocker again.

Before you get started doing a repair install of Windows 10, be sure that you also temporarily disable Secure Boot in your UEFI firmware settings. Once installation has finished, you can enable Secure Boot again if you like.

  • System Protection will be reset to the default of being turned off. It is recommended to turn on system protection after the repair install has finished to have restore points.
  • You will lose any custom fonts.
  • You will lose any customized system icons.
  • You may need to re-establish your Wi-Fi connection.
  • You will need to redo Windows updates subsequent to the build you have used for the repair install.
  • Windows.old will be created.
  • You will need to redo any language downloads including the display language if you changed that.

Starting with Windows 10 build 18298, Microsoft made some adjustments to the design of Windows 10 Setup when running setup.exe from a Windows 10 ISO file.

This tutorial will show you how to do a repair install of Windows 10 by performing an in-place upgrade without losing anything.

You must be signed in as an administrator to be able to do a repair install of Windows 10.

“Windows Recovery Disk May Become Obsolete”:

See the Infopackets article by John Lister on August, 1 2019 at 09:08AM EDT.

Microsoft may be ending the need to have a physical disk to reinstall Windows 10. A 'Cloud Download' option could save time and hassle.

At the moment, the main way to reinstall Windows is to use a recovery disk (or a copy of the relevant files kept on a hard drive or USB device.) That's got a few limitations, most notably that not everyone who gets a recovery disk with a new computer will be able to find it.

Other problems are that recovery disks don't always have the drivers necessary to make sure Windows 10 works smoothly with a specific PC, and that the disks don't usually work well for people on the Windows Insider test program.

Cloud Download a New Option

There's also the headache that once somebody reinstalls Windows from a recovery disk, they'll need to download all the security and feature updates Microsoft has released since the disk was made. That's more of an issue with Windows 10 where the update schedule is planned to run indefinitely.

While Microsoft hasn't commented publicly on the changes, they've been spotted by an avid user of Windows Insider. The latest test updates include a new screen that will appear when somebody boots up the computer and selects the reinstall option.

That will now ask "How would you like to reinstall Windows?" and offers two options, "Cloud download: Download Windows" and "Reset locally: Reinstall my existing Windows operating system." (Source: zdnet.com)

Given the technicalities of this particular set of tests, the most likely point for this change to take effect is Windows 10 20H1: in other words, the first of the two major updates expected next year.

No Need To Burn Disk

Windows users can already download the latest version of Windows 10 for recovery purposes, but that involves burning the files to a DVD to create a recover disk. This new option looks like it would be a one-click affair to download and reinstall Windows.

There would still be some limitations, most notably that the method would only work if the computer isn't so screwed up that it can't get an Internet connection.

Fun Facts:

“Can you do Percentages in your Head?”:

Try calculating 32% of 75 without help from calculators.

Not easy?

How about switching the numbers and doing 75% of 32 instead.

Now, that's easy. Finding 3/4 of 32 gives 24. Correct!

Ah, but does this trick always work, and can you prove it?
