Hello and welcome to our Reasons to Defrag Hard Drive. You ought to defrag your hard drive, in case your PC is slow. This could enhance the efficiency and pace of your PC too as its hardware longevity. It places them where there is space, whenever your PC saves files. Often files are separated into bits. For example, whenever you remember a file and focus on it, it frequently doesn't fit back in exactly the same physical place. Where it can your PC divides up the file, occasionally into several parts, and saves it.

Why defrag?

Fragmentation causes difficulties that doing a defrag can correct. Fragmented files because it requires more resources and time to locate and remember these files slow down your pc. Applications may also take longer to load. Defragging can prolong the life span of the components. A defragged hard disk too can raise your likelihood of recovering lost information. Once fragmentation starts, it can propagate fast -- demanding defragging. It's like the pages of a publication are divided and hidden in several locations around a house, if a file is fragmented. It's like the pages of the book being brought back together, should you defrag. Defragging discovers all the bits of the file and places them in contiguous, actual places.

How will you defrag?

To defrag your hard drive, you must utilize software or utility. There are lots of defragging tools available. SpeedyPC Pro, a whole package of cleaning and optimization tools, can defragment your PC. Before you defrag, it's best to assess your hard drive. This evaluation finds if a defrag is needed and how much of the disc is fragmented. You simply allow the application do the work if it's determined that you must defrag your PC to enhance performance. To be able to defrag a drive, free disk space will be required by your PC. Defragging can take a while. How long depends on several variables, such as the system resources accessible, the disc volume, the number of files, and how fragmented the files are. It's a great idea to defrag when you don't have to use your pc or it isn't doing other jobs. For example, the night could become a great time to defrag. Be certain to close out of resource-intensive applications, like your antivirus scanner, before you defrag.

Having an eMail in today's modern world is no longer a privilege or being geeky, it has surely become a necessity. From Facebook to LinkedIn or Steam many services today require you to have an account in order to use them, and in order to create an account, you need working eMail. That being said many people today have several eMail accounts, one for social media, one for work, maybe even one for very close friends and family. How creating eMail today is completely free we might end up with several eMail accounts. eMail clients have also evolved much since their first days and became more than just applications for receiving eMails, today they can take various different tasks having additional features built into them like calendar, batch eMail processing, etc. Taking all of said into account I am presenting to you within my personal opinion some of the best eMail clients starting with free ones.

Best free eMail clients

Google Gmail

https://gmail.com It would be very difficult to even start a free eMail list without mentioning Google's Gmail. Introduced all the way back in 2004 as an invite-only service it became over time the most popular email platform largely due to the fact Google is offering free eMail accounts. There are a lot of good things to be said about Gmail itself, most of the area is clutter-free and the largest space is reserved for eMail itself letting users focus on what is important. WEB client itself means that you do not need to have any application installed on your device, altho via Google chrome, you can use Gmail offline offering you flexibility if needed. The ability to connect and manage other accounts like Outlook, Yahoo, etc is just making Gmail even more attractive, and the snooze feature is a really neat little detail that will pause eMail notifications if you need to focus on other things. Lack of organizing messages into folders is a little confusing since Gmail offers its own unique label system but sometimes I need to have old reliable save eMail to folder. All in all, Gmail is a great service and it offers a great eMail on the go experience.

Mail eMail client

https://www.microsoft.com/en-us/p/mail-and-calendar/ Free Windows eMail client simply called Mail is what was once outlook express. Mail itself has the ability to work with other popular accounts like Google Gmail account, Yahoo, iCloud etc. How it comes with Windows OS and it integrates very well with Microsoft Calendar, this eMail client is for many the first choice. On the negative side, I might say this is a strip-down version of Outlook which is paid solution so some features are missing if we would compare the two. Overall, a simple and nice eMail client worth your time, especially if you are on the Windows platform.

Mozilla Thunderbird

https://www.thunderbird.net Great eMail client matching in functions against paid and premium solutions of big tech companies. Fueled with plenty of customization options and reskinning ones this eMail client offers a lot for its free price tag. It is also fueled by Mozilla community focusing on privacy and security. It can work with any mail service and it is lightweight with a clean look, altho the look itself can be heavily customized. The bad side is that client itself relies on email services to provide cloud-based emails, so if you are receiving your email via a service that does not have a cloud-based service in itself all of your received emails will be locked to the computer where you have received them. Also customizing it can be sometimes a little too technical for the average computer user. All in all, Thunderbird is one great eMail client and it would be a shame not to use it because of its technical side, if you need a reliable and secure eMail client on a single machine, look no further than Thunderbird.

Paid eMail clients

Microsoft Outlook

https://www.microsoft.com/en-us/microsoft-365/ Outlook comes as a part of the Microsoft Office suite and as one of the oldest eMail clients, it is still widely popular and adopted through many users and businesses. It has tight integration with all Microsoft services and full integration with Calendar making it one of the if not the best eMail client out there. Outlook also has a free online service completely free for personal use as well. The downside is that you can not get it as a separate product if you want a business version other than as a part of the Office suite. The final verdict would be that this is perhaps the best eMail client out but the big downside is that there is no desktop version outside the Office suite.

eM Client

https://www.emclient.com/ eM Client offers a wide array of features, including a calendar, contacts, and chat. Support is provided for all the major email services including Gmail, Yahoo, iCloud, and Outlook.com. The latest version also offers PGP encryption, live backup, basic image editing capabilities, and auto-replies for Gmail. Its automatic system makes it very easy to get emails from other services since there is no manual setting, all that is needed is to type in your email and eM Client will do everything else automatically. A one-time purchase is not pricy and it could offer some features that some free clients are missing. Go check it out with a free trial and see if it is for you.

Mailbird

https://www.getmailbird.com This eMail client's main focus is the simplicity of use with visual appeal while tackling multiple eMail accounts. It has many built-in apps along with a customizable interface. Unlike some more Microsoft-centric email clients, Mailbird Business supports a diverse range of integrated apps, including WhatsApp, Google Docs, Google Calendar, Facebook, Twitter, Dropbox, and Slack, all making for a better-streamlined workflow. The downside of this client is the yearly subscription plan. I think people, in general, want to get away from software subscription plans so I will include this as a downside but bear in mind it is downside just in terms of a business plan not in the client itself.

Inky

https://www.inky.com/ Inky is eMail client if you are looking for security. It uses AI along with machine learning in order to block all types of phishing attacks that can get through to other clients. The proprietary machine learning technology can literally read an email to determine if it has phishing content, and then is able to quarantine the email or deliver it with the malicious links disabled. It also takes things a step further and offers an analytics dashboard, which allows an administrator to see patterns of attacks based on dates, or targeted users. The downside is that client itself is so much focused on security that sometimes some nonsecurity features get overlooked and provide a poor experience but if you need a good and greatly secured eMail client Inky is one to check out.

In today's digital life, when we access the internet daily, browsers are essential almost as our operating system, after all, we do access all of the internet data via them, and having a good, reliable, and personal browser tailored for our needs can make all the difference in the world. In today's article, we will introduce you to the five greatest browsers of today, we will point their advantages and disadvantages and why should you pick one or another. As with each piece of software, there is not an ultimate browser, better than anything else and we will not favor anyone on this list, the decision which you should use is solely up to you, we are here to provide you with an objective opinion on each one. All of this being said, let's begin with the countdown in no particular order.

1. Mozilla firefox.

   If you consider yourself a power user or you value your privacy then firefox is the browser for you. It is open source and is packed with great features like reporting when your email has been used for a known data breach, it stops annoying pop-up notifications, stops browser fingerprinting, and many more. Firefox is also a cross-platform browser making it a great choice if you want to transfer and use your data across multiple devices with one account. The downside of firefox however is its speed, this browser is the slowest on this list, I guess features and advantages took their tool in the speed department, but if that is not a concern for you and you feel like the positives outweigh some slower speed, grab it here.

2. Google Chrome

   Chrome browser has been a game-changer when it was released and even today some of its features are still great and needed. It is packed with some great features like tab freezing, for example, it is cross-platform meaning that also as firefox you can change data between browsers on different devices. it is a very expandable browser with tons of extensions and its speed performance is very very good. The downside of Chrome are two things sadly, one of them is its hunger for RAM, the browser takes a big chunk of RAM once it is active and on some older computer with limited RAM it performs slowly, another is telemetry which its sending, in other words, other browsers don’t come with the lingering fear that Google’s just a little bit too involved in all of our lives. But if downsides do not trouble you and you have a decent amount of RAM in your system chrome might be the best solution for you, grab it here and check it out.

3. Microsoft Edge

   Or should I say Microsoft edge 2.0 since this new Edge is completely recoded and rethought, a completely new browser based on chromium. The first version of the edge was an inhouse attempt from Microsoft and it was a disaster, I guess the lesson was learned, and this new edge we have today is a great Browser, it is lightning fast and packed with some great features with one among them standing out I just love, that is the ability to save web pages as applications and truth to be told you have to try this in order to see al great advantages it offers. A very interesting feature is that edge itself wins the speed race from all of the 5 contestants here which is a great surprise. Of course, the downside of annoying Microsoft pushing it to be your default is, well it's Microsoft, as chrome is tied to Google so is edge tied to Microsoft, and the same dreaded feeling that big MS is watching you. If however, you do not concern yourself with these kinds of things, since it is already part of Windows 10, give it a spin and try it, I am sure you will at least love its blazing speed.

4. Vivaldi

   A new kid on the block, relatively unknown Browser Vivaldi offers some great customizable features no other one on this list offers, a very unique and down to each detail customization option, you can literally tweak each and every aspect of this browser making it best customizable and personal browser ever. How it is also based o chromium, every chrome extension works in it naturally. It is very good in speed and constantly updated and developed. The downside, well if you are anything like me, you could spend ages trying to customize it, ages, it has tons of features, and making it really feel and tick as you want can consume a really lot of time. If this thing does not bother you at all, grab Vivaldi here.

5. Opera

   Last but not least, we have another relic of the old browser age, the Opera browser. Packed with great security and great in-house features like a built-in VPN, built-in ad blocker, built-in crypto wallet, etc this browser seems like a swiss army knife. Opera is full of features and it shows once you start using it. The downside of opera is that its look and feel are specifically tailored to a certain type of user and not everyone will find that appealing or attractive, add some great but hidden and hard to come by features and it may go unnoticed. However, I think you should really give it a go since it definitely deserves more attention than it gets. Grab it here and check it out.

That's it, 5 great browsers to look up, I hope that you have enjoyed the read and I hope to see you again here for more articles. If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

Microsoft sent an email to users on the Dev build channel saying that the company intends to push some builds that don’t represent what consumers will receive with Windows 11 when it officially releases. In other words, these are going to be some rather buggy builds that won’t be too enjoyable to use. The company recommends users switch from the Dev to the beta channel if they aren’t prepared to deal with the instability. We’ll have to wait and see just how buggy these builds are, but if Microsoft is actually sending out a warning about them it is very likely that builds will be plagued with issues and maybe even stability problems.

Back to Windows 10

How we can expect some buggy build of Windows 11 if you prefer a stable system over new features maybe best decision would be to switch back to Windows 10 until the new OS hits official release.

Switching from dev build channel to beta channel

Another solution, if you do not want to deal with too many issues, is to switch from Dev build channel to beta where things will be more stable. Follow the guide below in order to quickly switch to the beta channel. Following instructions only apply to Windows 11 installations that are linked up to the Windows Insider program, not clean installation of OS.

1. Press ⊞ WINDOWS + I to open settings
2. Inside settings click on Windows update
3. In Windows Update click on Windows Insider Program
4. Inside click on Choose your Insider Settings
5. Click on the button next to Beta Channel to select it (you can switch back to the Dev channel here if you change your mind)

The setting will be saved automatically and from now on you will only receive beta channel updates.

If you are testing your headphone or your speaker but all of a sudden encountered an error that says, “Failed to play test tone” in your Windows 10 computer, worry not for this post will walk you through how you can fix this problem. The test tone is used to check the right-left balance of the headphones and speakers in your computer, however, if you are not able to use it, there are several options you can check out. You can try to run the Playing Audio troubleshooter or restart the services that are related to Windows Audio. Aside from these, you could also disable Audio Enhancements or you could also change the default test tone rate and bit depth.

Option 1 – Try to run the Playing Audio Troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to restart the Windows Audio-related services

The next thing you can do to fix the problem is to restart the services related to Windows Audio. Although the audio services start automatically on every system boot, there are times when they might fail to start. Thus, you can start these services manually by following these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Services Manager.
• Then look for the services named “Windows Audio” and “Windows Audio Endpoint Builder”.
• Double click on each one of these services and check if their Service Status is set to Running or not and also check if the Startup Type is set to Automatic.
• If none of the services are running, just click on the Start button and select the Automatic option from the drop-down menu.
• Now click on the Apply and OK buttons to save the changes made and then check if the error is fixed.

Option 3 – Try to update the Audio driver

You might also want to consider updating or the Audio driver as it could help in fixing the error.

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
• From the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.
• Then also click on the option, “Search automatically for updated driver software.
• Restart your PC after the installation.

Note: If updating or reinstalling the Audio driver didn’t work, you can go to the manufacturer’s website and look for the support section where you can download the drivers for your computer. You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 4 – Try changing the default test tone rate and bit depth

Windows selects a default test tone rate and bit depth depending on your headphone or speaker. This allows you to look for the best sound quality from your audio output device. So if your headphone or speaker has some problems with the default settings, then it’s no wonder why you’re getting the “Failed to play test tone” error. To fix this, you can try to change the default test tone rate and bit depth by following the steps below.

• First, you need to open the Windows Settings panel and then go to System > Sound.
• Next, look for the Device properties option located on your right-hand side and click on it.
• After that, select the Additional device properties option and go to the Advanced tab.
• From there, select a different test tone rate and bit depth and then click on the Test button.
• Once done, check if it was able to fix the problem or not.

Option 5 – Try disabling the Sound or Audio enhancements

To make your operating system’s specific hardware sound nothing but perfect, both Microsoft and third-party vendors have shipped audio enhancement packages which are usually referred to as “Audio Enhancements” in Windows 10. However, there are instances when instead of improving the sound or audio quality of your computer, it can cause problems so to fix the problem you need to turn off these audio enhancements. How? Simply follow the steps below.

• Type in “Sound” in the taskbar search and then from the list of results, select “Sound Control Panel”.
• After clicking Sound, the Sound properties box will pop up. From there, go to the Playback tab and right-click on the default device i.e. Speakers or Headphones then select Properties.
• After that, the Speakers properties box will appear. From there, go to the Enhancements tab and select the checkbox for the “Disable all enhancements” option.

The latest security vulnerability was discovered inside both Windows 10 and Windows 11 letting any user access admin privileges inside the operating system. This can, of course, be used by a potential attacker to get full control of the system. The problem lies in Microsoft's security rules assigned to the Windows Registry and the Security Account Manager. Both for some reason have reduced restrictions allowing any local user to fully access the files without administrator privileges. The problem is even more amplified if we think about Security Account Manager which includes all account data including the passwords of all users using the same PC. This can provide a potential attacker with all information and let them log on into the administrator account for full control. Microsoft is aware of the matter and is tracking it with code CVE-2021-36934, and includes a complete workaround for the issue, which includes restricting access to  %windir%\system32\config and deleting any restore points or Shadow volumes that were created before that point until the hole is plugged with an official security patch.
