New Option for Microsoft Defender

Keeping Microsoft’s operating systems up to speed on the newest cyber attack defenses has been a top priority for the company over the years. Recent effort by Windows developers has resulted in the creation of a Microsoft Vulnerable Driver Blocklist.

“Security, simplified. Microsoft Defender is your personal defense against digital threats. Secure your devices across operating systems including Windows, Apple, and Android.”

It is hoped that by implementing this blocklist, suppliers would take the security of their drivers more seriously.

Universal Control on Mac

Apple’s operating system is getting a slew of new features, many of which were introduced at WWDC. One of which is Universal Control.

According to MacRumors, “Universal Control streamlines multi-device workspaces by allowing you to use the same peripherals across multiple Macs and iPads.

With Universal Control, you can use your main Mac’s trackpad and keyboard to control additional Macs and/or iPads nearby, so you don’t need a desk cluttered up with more than one set of input devices.”

It’s possible with Universal Control to use a single set of keyboard, trackpad, and mouse controls on a variety of Macs and iPads. You may now slide your mouse cursor off the edge of your Mac, and it will appear on the iPad when you set it adjacent to the computer. iPad keyboard and trackpad functions are identical to those on a Mac, and material may be transferred between both.

It’s best to note that this feature is still in the beta phase. This means if you would like to try it out, you’ll have to manually turn it on. Go to System Preferences ——> Displays ——-> Universal Control to access it.

Hard Drive Failure Issues

Depending on the circumstances, the failure of a hard drive might have disastrous implications.

The procedure of replacing an old hard drive with a new one is straightforward; however, data stored on the old hard drive may get damaged or lost during the replacement process. In addition to using your current hard drive as a secondary disk after installing a new hard disk on your computer, you may connect your current hard drive to the computer using a USB cable.

The vast bulk of the information provided is that which is currently saved on the computer’s hard drive. Having restored your data, you will be able to remove the corrupt hard disk from your computer. Making frequent backups of your most important files and papers is one of the most efficient strategies of protecting your data.

In the case of a hard disk failure, Google Drive or other free cloud storage services are fantastic solutions for keeping data online that can be retrieved rapidly.

Search Highlights Feature

Windows 10 and 11 developers are constantly coming out with handy features to make work, school, and personal agendas flow easier. A new feature in the Search app called Search Highlights allows you to see popular search terms, holidays, and significant dates in your area from inside the app.

An announcement from Microsoft discusses progressive rollout to consumers over the next weeks and that it might take months for all users to get access.

We are taking a measured approach starting with the March 2022 Cumulative Update Preview for Windows 10, and broad availability will occur in phases. Devices running Windows 10 who have installed the March 2022 monthly quality update (or later) will be included in this phased rollout.

To utilize this function, click the Search bar in the taskbar; you should see a new interface with Search Highlights. You may click a result to access it in your web browser.

PC Crashes After Turned On

It can be frustrating when your PC crashes, unable to load the operating system. This may be the culprit:

There may be an issue with your PC’s RAM or hard drive if it boots up to the manufacturer’s logo before crashing. Both RAM corruption and hard drive damage are possible explanations for why an operating system cannot be loaded.

If you have more than one RAM slot, removing one at a time and restarting the computer can help you identify the problem. Finally, you’ll have to get a new RAM module or a new hard drive to fix the problem.

However, if that isn’t the case, Karls Technology would be happy to assist!

E-Mail Attachments Not Opening?

It might be really aggravating to open your e-mail only to find attachments that would not open. What may be the source of the problem? The majority of the time, this is due to the file format and a lack of a reading application on your computer.

Not sure what kind of file you have or what application you’ll need to open it? Simply look up the file extension online (the three letters that appear after the file name e.g. pdf.) If the file name lacks an extension, you’ve discovered the issue; simply re-save the file and manually add the appropriate extension initials, and the document should be viewable.

Computer Hope explains you should ask “the sender save the file as a different format that the computer supports and re-send the attachment. If you are going to be working with this file format often, install a program or viewer on the computer that supports the file format. Below is a listing of some of the more common file formats send over e-mail, their file extension, and the programs used to open those files.”

DNS Cache Clearing: How To

A Domain Name System (DNS) server converts recognized domain names into IP addresses, which computers use to connect to one another. When an application attempts to connect to a domain name, your computer searches the Internet for a DNS server to obtain the accompanying numeric IP address.

Windows 10 saves a copy of the information it receives from DNS servers locally on your PC to save time. This is referred to as the DNS cache.

The DNS cache is stored in system memory rather than a file on your machine. The system memory is cleared every time you shut down your computer, which helps to explain why restarting your computer solves so many problems.

To clear your DNS cache, all you need to do is to restart your computer.

Change Default Browser on Mac

Apple’s Safari is the default browser for browsing the web on macOS. Over recent years, however, users have been running into too many problems with Safari.

According to 9to5Mac, “By comparison, 10.38% of desktop users were surfing the web with Safari in January 2021, which suggests that Apple’s web browser has been losing ground to other alternatives. If Safari continues to lose users, it will probably slip to the third or fourth place in the ranking over the next few months.”

Thankfully, you can change your preference. Other browsers you can utilize include Chrome and Firefox. Because all of the frontrunners are free to download, the best thing to do is install them, test them out, and keep the one you like most. Then you may set it as your default browser.

Changing your default browser is super easy. Simply, go to System Preferences and select the General icon. From there, go to the dropdown menu next to Default web browser. You can choose whichever browser you’d rather use.

That’s it! Which browser do you prefer?

Warning for iOS 15.4

Apple released its iOS 15.4 update to its iPhone users. Unfortunately, this update came with a plethora of security issues.

It was stated that Apple has worked on fixing the 39 known security problems. Some of the issues included WebKit, which assists the Safari browser.

Forbes states on their website, “Even so, many of the issues fixed in iOS 15.4 are serious, which means you should update your iPhone now if possible. There are vulnerabilities that allow for Kernel level access, which is “about as bad as it gets,” says independent security researcher Sean Wright.”

Several of the flaws that Apple has recently addressed, such as the single but critical weakness repaired in iOS 15.3.1, were resolved after they had been exploited to attack iPhones. None of the vulnerabilities resolved in iOS 15.4 are currently being actively exploited, as noted in the Apple support page.
