Microsoft will soon offer 4 CPU computer specifically aimed at developers and its name is Volterra. The machine as stated will come with 4 processors but the strange thing is that they will be ARM-based instead of x86.
CEO of Microsoft, mister Satya Nadella has introduced the product and Microsoft has released a youtube video promoting it.
The computer system will have Qualcomm's NPU or built-in neural processing unit to use AI's power to help developers write and produce better and faster code. The sad news is that besides processors used there is no other information on other components that will go into this system.
As seen in the video, the computer reminds me a lot of the apple MAC mini with its size and design, and as stated it is made from recycled plastic which in our opinion will bring the price under $1000.
Microsoft has not provided an official price tag for Volterra, but our hope is that it will be more affordable than building your own development PC. Also, there was nothing said about computer availability, we suspect that the selling model will be typical Microsoft one with first models available only in the USA and moving forward slowly opening it to other markets.
As previously said nothing except the number of CPUs and their type has been officially said but we managed to get some information about some other specific things not including its inside components.

The unit will have a fan inside of it for cooling purposes and better performance and that is what was officially stated by Microsoft. On the outside, it is known that the computer will have three USB-A ports, a mini DisplayPort, and an ethernet input. All of these will be positioned on the back of the device, on its left side there will be two USB-C ports.
The unit itself will be running on Windows 11 but it was not disclosed anything about the version, we presume since this is a model aimed for professional use that it will come with Windows 11 PRO version.
Since this product is aimed at developers logically support for developing software is a must-have and at the time of this writing software that will come and that will run on Volterra is:
Once MAC studio has been released it showed that specific builds have their audience and can be sold for less of a price than full-fledged custom-made workstations. There is no doubt that Microsoft Volterra will find its audience but will that be enough to have more versions of this compact computer only time will tell.
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.
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.
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.
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 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.
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 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. “Installing, this may take a few minutes… WslRegisterDistribution failed with error: 0x8007019e/0x8000000d Error: 0x8007019e/0x8000000d The parameter is incorrect. Press any key to continue.”Error code 0x8007019e or 0x8000000d could be due to the absence of supporting Windows 10 features since the error does not even let one use the WSL-based command line. If you are one of the users facing this problem, then you’ve come to the right place as this post will provide you with a couple of suggestions to fix it. There are two options you can check out to fix the problem, but before you do that, you need to make sure that the Windows Subsystem for Linux feature is enabled. The two options include enabling WSL using the “Turn Windows features on or off” option and using the Windows PowerShell.
“This policy setting lets you prevent Windows from using diagnostic data to provide tailored experiences to the user. If you enable this policy setting, Windows will not use diagnostic data from this device (this data may include browser, app, and feature usage, depending on the “diagnostic data” setting value) to customize the content shown on the lock screen, Windows tips, Microsoft consumer features, and other related features. If these features are enabled, users will still see recommendations, tips, and offers, but they may be less relevant. If you disable or do not configure this policy setting, Microsoft will use diagnostic data to provide personalized recommendations, tips, and offers to tailor Windows for the user’s needs and make it work better for them. This setting does not control Cortana tailored experiences, since there are separate policies to configure it.”
“Shell Infrastructure Host has stopped working. A problem caused the program to stop working correctly.

And to fix this error, there are several options you can check out. You can try to reinstall the Microsoft Redistributable Packages or run a System File Checker scan. In addition, you can also use a new Guest Account or troubleshoot the problem in a Clean Boot State.
