Alto, I personally am a big fan of alt-tabbing, I must admit that I am not a big fan of having multiple browsers tabs on screen when I do press key combo. Luckily there is a very easy way to turn this feature off.

These methods do require some advanced knowledge and computing skills, so if you are unable to complete the steps below successfully or do not have confidence in your ability to undertake these methods on your own, contact a qualified computer repair service that is familiar with the Windows 10 installation process.
Error CausesThere are a few different issues that can cause Error Code 0x8000222 to arise during the installation process on your Windows operating system. The first is a corrupted file in your system library or dynamic link library, also called the DLL. The second is interference by your proxy, firewall, or antivirus software that inhibits the machine from being able to access the files that it needs to successfully complete the installation of your Windows operating system or software.

Keep in mind that these steps do require some advanced skills and knowledge about your computer, so if you don’t believe that you can undertake these steps on your own or if the following methods do not fully resolve the issue on your device, talk to a qualified computer repair technician for assistance.
Here are the best ways to address Error Code 0x8000222 on your Windows machine:
Before implementing this method, make sure that a proxy is not active on your computer. To check to see if there is an active proxy, simply press the Windows key together with the “R” key and type in the command “cmd”, then when the prompt opens up, type in the following command: “netsh winhttp import proxy source=ie”. From the box that follows, if you see a message saying that there has been an error writing in the proxy settings and that access has been denied, it means that you can turn off the proxy setting in your Internet Explorer and the error will go away on its own.
If you do not have an active proxy, it is time to check and see whether your DLL dependencies are properly set up. To do so, open up the command prompt again by pressing the Windows key and “R” key at the same time and typing in “cmd”. Once the command prompt is active, simply typing in “regsvr32 Officevalidator.dll”, then attempt to resume your installation once it has been complete.
In some cases, you may need to restart your computer before attempting the Windows installation process.
If the above method did not successfully resolve the problem, you can go into your control panel and turn off any firewalls or antivirus programs that may be interfering with your ability to complete the Windows installation process. Depending on the programs that you use for your antivirus needs, you may need to restart your computer before you reattempt to do the installation process.
You should be able to turn your firewall and antivirus programs back on once the installation process has run through to completion.
In most cases, taking the steps above will fully resolve the appearance of Error Code 0x8000222 on your Windows 10 machine.

Error CausesComing in October for insiders and in November for all in the update, Microsoft has prepared a series of updates which they call an "additional set of experiences"
These updates are looked upon by Panos Panay, a vice executive president at Microsoft & chief product officer for Windows and devices as sort of makeup tests. They will consist of new additions with the biggest one being a tabbed version of File Explorer.

File Explorer received a UI makeover in the last update but the tabbed interface was missing which was expected by many users so it will come in following the next update.
The rest of the features that we will receive are an updated Photos application, Suggested Actions in the Windows Shell, Overflow menu for the taskbar, and improved Nearby Share.
The tabbed File Explorer interface is essentially File Explorer’s version of Sets, the tabbed window interface that Microsoft tested out several years ago. In testing, the tabbed interface proved handy for moving and copying files, and we’d expect the same once the feature formally goes live. The difference between Sets and the tabbed File Explorer interface is Sets allowed for multiple applications to be clustered together via tabs.
Photos app will include a “new photos-managing experience that brings a gorgeous gallery, simplifying browsing, finding, management and consumption of your collection of photos.” It will allow “easy backup to OneDrive” and a “delightful Memories experience.”
As for other features, nothing specifically was said except giving just some tips on what will they bring, it is obvious that File Explorer and the photos app were the main focus for MS in this upcoming update.
