Microsoft store is ready and prepared for Windows 11 official release on October 5^th and it is coming with some surprises. It has officially confirmed that many open source and free applications will be in it like Opera, VLC, discord, Libre office, etc. It seems that Microsoft wants to place its store as one place to go for all of your software needs. Another great surprise is the coming of Epic games store implementation. It was officially confirmed but not explained in detail, will we have Epic store opened in Windows store or we will only get installer as a package we will see but this is some great news. As for how it states now, it seems that the Windows store aims to eliminate searching the web for applications and bring them all into one environment with reviews and ratings so you know which one to install and use. It also features a great search engine to find proper applications for your needs. The new store will come to Windows 10 as well but after all Windows 11 has been mostly released and adopted. So expect it via update in two or three months' time. It would be great if some larger companies decide to join MS stores like Autodesk, Adobe, the Foundry, etc so you can install everything you need from it but one can only hope.

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.

If you got the Microsoft Store error code 0x80072F30 while trying to open Microsoft Store, then it indicates that the Store fails to connect to the internet or is not able to launch successfully for some reason. It could be that the Windows Update Service has stopped or the Windows Store cache might be corrupted or it could just be due to a poor internet connection. Whichever the cause is, you have to fix this error so that you can use Microsoft Store again and you won’t be getting the following error message every time you open the app:

“Check your connection, Microsoft Store needs to be online, It looks like you are not, error code 0x80072f30.”

The error code 0x80072F30 is related to the Windows Store which prevents it from opening properly. To resolve this problem, you can try fixing the problem with the help of the options given below. Follow each one of them carefully.

Option 1 – Check your internet connection

The first and most obvious thing you can do is to check your internet connection. This may only be a basic tip but it sure works like a charm in most cases. And if you have another internet connection available, you can also try connecting to that and see if you can pull up Microsoft Store or not. 1] Change your internet connection: A basic tip, but sometimes works like a charm. You may want to check if your internet connection has an issue, or you can also try opening a website and see if you can open it and if possible try connecting to a different internet connection and see if the Microsoft Store opens for you. We also suggest you try changing your DNS and see if it helps.

Option 2 – Check the date and time as well as the time zone of your PC

A lot of services and apps rely on the Date, Time, and Time Zone of your PC which is why if they are not configured correctly, a request from the client machine will be rejected from the server and the same thing happens with the Microsoft Store.

• First, go to Settings > Time and Language.
• From there, check if it is set to Automatic or not – if it is, switch the toggle button off to set the Time and Time zone manually.
• Then select the right time zone manually.
• On the other hand, if the Time and Time zone is set manually, you have to switch the toggle button on to set Time and Time zone automatically.
• Restart your PC and afterward try opening Microsoft Store again and check if the problem’s fixed or not.

Option 3 – Run the Network Adapter Troubleshooter

Since Windows 10 is packed with various troubleshooters – one of which is the Network Adapter Troubleshooter – you can use it to troubleshoot the problem. To use it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 4 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again.

Option 5 – Check the Windows Update Service status

You might also want to check the status of the Windows Update Service since the proper functioning of this app depends on the Windows Update Service. It could be that there is some issue with the service which is why you’re getting the error code 0x80072F30 while trying to open Microsoft Store.

• Tap the Win + R keys to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter to open Services.
• Next, look for Windows Update Service from the list of available services in Windows.
• Once you see it, check if its status is STOP or Pause and then change the status to Automatic.

If you are starting to get into the “wonderful” world of coding there is a high chance that you have heard of GitHub or Git for short and there is a slight chance that you might be confused about what exactly GitHub is. If this is the case, we are welcoming you to go through our article and find everything about it and why it is so popular and used all around the world.

What exactly is GitHub?

If we want to go all technical and just point the obvious we could say that GitHub is basically a WEB site and cloud service used for storing and managing code in all languages. But to truly understand why you should use GitHub and not Dropbox or any storage service instead you need to understand concepts like Version Control and Git.

Version Control

Version control is meant to help developers to work separately on different parts of codes and update is separately not breaking the original one. Take note that this option is meant when there is a big project and has more than one coder working on it. If you are a solo coder on your personal project this might not be anything groundbreaking for you personally. But let’s now assume that you are part of a team and that your task is to edit only one function of a project and other people working will also have their tasks. With version control, you could take only part of the code and work on it and once you are finished merge it back into the main repository. All changes in the main code are automatically tracked and can be easily reverted back if needed. The good stuff is that rolling back can be used only let’s say on a code you submitted and other changes made to the source can be kept. As you can see this makes a very good and efficient working space and a good coding environment.

Git

Git itself is a specific version control system, an open-source version control system to be more precise created by Linus Torvalds in 2005. It is a distributed version control system, which means that the entire codebase and history is available on every developer’s computer, which allows for easy branching and merging. Currently, over 87% of worldwide developers are using Git on a daily basis.

So GitHub is?

GitHub is a profit company that offers a cloud-based Git repository hosting service, in other words, it automates and makes it easy for everyone to use Git for version control and collaboration. It focuses on user interface and ease of use so even beginner coders can use it right away without any large confusion and using command lines and setting it themselves manually. GitHub also has a free personal plan in which you can host a public code repository completely free. This option placed GitHub very popular with open source projects. If you are a company you can purchase a plan to have a private code repository shared only to members of your team or company.

Conclusion

As stated almost every developer on a planet uses some version of Git, many of them are on GitHub and there is a lot of open source projects on it. Some employers even ask to see your GitHub repository when deciding if they want to employ you, think of it as a portfolio for coders. There is not a single disadvantage and not a single argument against using it, especially it has a personal free option. So if you want to look better and more professional in the coding world go, make an account and place some code on it, share it with the world, and see how it goes. You might even get some help on projects from other coders if you need it.
