One of the selling points of Windows 11 was the ability to run Android apps natively in it without the need for any third-party software. It is not a big surprise that even after its release Microsoft is evolving and expanding Windows 11 and its features.

Microsoft is now rolling out an update for the Windows Subsystem for Android on the Dev Channel of the Windows Insiders program. The new version upgrades the core operating system from Android 11 to Android 12.1 (also known as Android 12L), which means the new system and app features in Android 12 and 12.1 are now available on Windows for the first time. However, not the new features in those updates apply to the modified version that runs on top of Windows. For example, one of the main improvements in 12.1 was a dual-pane notification panel for larger screens, but Android app notifications on Windows just show up in the Windows notification panel.
The upgrade also improves how Android apps integrate into Windows. The Windows taskbar will now show which Android apps are currently using the microphone, location, and other system services — similar to many native Windows applications. Toasts messages (the small popups that some apps use for temporary messages) are now displayed as Windows notifications, and the titlebar on Android apps will use the current activity name for the title.
Full changelog
The new update is limited to Windows Insiders for now, but once Microsoft fixes all the bugs, it should start rolling out to everyone on Windows 11 that has the Android Subsystem enabled.

Error CausesAfter upgrading to Windows 10 operating system from Windows 7 or Windows 8/8.1, a lot of Windows users are complaining about the Windows setup in a continuous reboot loop. The computer would just keep on rebooting every time the machine is booted and this incites frustration for a lot of Windows users.
Error CausesWhen Windows launched the third update for Windows 10, users trying to upgrade to Windows 10 encountered an endless reboot loop problem. The computer will crash repeatedly. The KB3081424, which is a roll-up of bug fixes of Windows 10, continuously fails once you start the update process and then triggers a message showing: “We couldn’t complete the updates, undoing the changes.” The undoing process will then cause a system reboot mandatorily.
Once you log back on your computer again, the Windows 10 update will try to reinstall KB3081424. You will not be able to stop the update which will cause your Windows setup in a continuous reboot loop.
The KB3081424 will not be successfully installed since if it fails for the first time, that initial failure can be detected to create a bad entry in your Windows 10 registry. This will then prevent your subsequent attempts to reinstall KB3081424 to make it work correctly.
In order to fix the problem of Windows 10 setup in a continuous reboot loop, there are a few methods you can try. Try following these simple steps and you’ll be able to get rid of the problem.
Note: If you’re not highly confident to solve this issue on your own, it is highly recommended to consult an authorized computer technician who would be knowledgeable enough to fix the issue for you. In addition, you can also use a system optimizer to resolve the issue.
Microsoft Windows released an updated fix for the Windows setup in continuous reboot loop problem. You can try fixing the issue through Windows Update.
Before KB3081424 attempts to install again, you can try doing this solution:
Another thing you can try to solve the Windows setup in continuous reboot loop problem is to perform a startup repair from a working computer.
NOTE: You must do this quickly since the BIOS loads rapidly.
Error code 0x800ccc0f is an error that occurs when users attempt to send/receive emails in Outlook or Outlook Express. Though information regarding the error is limited and sometimes difficult to decipher to those unfamiliar with error code issues, the following are possible symptoms users can expect when this error occurs:
Error CausesErrors in Outlook or Outlook Express may occur due to a multiplicity of reasons. It may be due to a problem with your network connection or the server. You may also encounter this problem after an extended period of inactivity.
Since the error could be due to one of many issues, several solutions are recommended. However, note that these suggestions require you to make changes that come with various risks. Be sure to implement these instructions correctly to avoid causing more problems to occur.
If you are not confident that you will be able to successfully implement the solutions below, get help from a certified Windows technician or IT professional.
As with other error codes, manual procedures are available which users can take to correct the problem. To implement manual repair, follow the methods suggested below:
Since error code 0x800ccc0f may manifest itself due to an issue with your network, you can seek to rectify the problem by first checking your connection. To do this, open an Internet browser. Type a valid web address in the address bar and click Enter.
If you are unable to access the website, you may then seek to fix the Internet connectivity issue by using Microsoft Automated Troubleshooting Services. These free tools are available for download on Microsoft’s website.
Not only can these tools fix your Windows Firewall – if this is the cause of your connectivity issues. These automated troubleshooting tools can also resolve other issues related to your Internet browser or network.
However, if after downloading and running these tools error code 0x800ccc0f still persists in Outlook or Outlook Express, implement the solution below.
Verifying your network connection is another way you can resolve your Outlook issues, i.e. once the issue is in fact a network-based problem.
To verify your network connection, make sure your computer’s network devices are turned on and fully functioning. Also ensure that the cables that connect your computer to a network are secure. You may also contact your Internet Service Provider (ISP) to verify your connection.
If there is no issue with your network and error code 0x800ccc0f persists, you will need to implement method three.
Problems with sending or receiving email messages based on the 0x800ccc0f error code could also be due to configuration issues for individuals who connect using a router. If this is a misconfiguration issue, you may be able to resolve the problem by bypassing the router and connecting through your modem.
Before doing this, however, be sure to check if your firewall is turned on as connecting directly can leave your machine vulnerable. Prevent attacks by checking your Windows Firewall setting. After making adjustments where necessary to ensure the firewall is turned on, test your connectivity to ensure you can access a connection. Also, check Outlook to see whether the error message has been resolved. If the error persists, consider the next solution.
Third-party apps like anti-virus software can sometimes cause interference, leading to errors. For this reason, check if the antivirus on your device is the source of the issue. Start by disabling the antivirus software. You may also turn off the software’s email scanning feature to verify whether or not that is the cause of the error.
Note that disabling your antivirus is only a temporary solution as it is not recommended that you use your computer without such protection in place. Consider replacing your antivirus or uninstalling and reinstalling for a permanent fix if indeed your issue with error code 0x800ccc0f was caused by interference from third-party apps.
Also, consider downloading a powerful automated tool to protect your machine from possible errors in the future.
