New Microsoft Windows 11 store
When Microsoft held Windows 11 presentation it took special time to present the upcoming new Windows 11 store as kind of a big deal. It was openly stated that with new Windows we will get a new store with a different attitude and new look.

microsoft storeNew Microsoft store

Microsoft has stated that both customer and developer feedback over time has contributed to their redesign and rethinking of the store itself. They want to be sure that policies for developers are more straightforward and clear so more developers will decide to bring their product to Windows. As for customers, they want more safety and more security so they feel protected when making a purchase. The new store will come in Windows 11 but also in Windows 10 as well via update.

Stories and collections

Introducing the new store will be curated stories. Microsoft believes that stores should be focused on user experience so stories from customers themselves will play a big role here. They are rich editorial content to keep you informed about the best apps and inspire you to achieve more with your device. This approach to information is aimed at bringing unknown applications to users via presenting them in a professional manner. Android apps in the store As stated in Windows 11 unveiling and presentation, Android apps will work inside Windows 11. Microsoft has teamed up with Amazon to bring you Android apps directly inside Windows via the new Microsoft store.

Pop up store from within a browser

When you are surfing on a certain webpage and want to save and install the application from there, a new pop-up store window will show allowing you to install the app directly. Microsoft has not said will this feature work outside their Edge browser so we will have to wait and see about that.

Support for multiple types of applications

Since now developers were tied to certain formats if they wanted to publish their application in any kind of environment. Microsoft wants to bridge this. Windows developers can publish any kind of app, regardless of app framework and packaging technology – such as Win32, .NET, UWP, Xamarin, Electron, React Native, Java, and even Progressive Web Apps. For Progressive Web Apps Microsoft has made open-source tool PWABuilder 3.

Flexibility and choice of commerce platform

Starting July 28, app developers will also have an option to bring their own or a third-party commerce platform in their apps, and if they do so they don’t need to pay Microsoft any fee. They can keep 100% of their revenue.

Google docs crush with repeating a word

A newfound bug in Google docs is causing it to crush and upon reopening it will crush again making it very difficult to re-access your document. The bug is manifested when a series of the same word is typed into a document and Show grammar suggestion is turned on.

google doc bug

How was it found

A Google Docs user, Pat Needham brought up the issue on Google Docs Editors Help forum.

"I've only tried in Google Chrome, with documents from three separate Google accounts (personal, G Suite Basic, and work one which might be enterprise). All three experience this same issue".

"It's case-sensitive. So trying with 'and. and. And. and. And.' doesn't cause it to crash."

While Needham publicly reported the bug, it appears that the issue was discovered by Eliza Callahan who was writing a poem novel for her novel using Google Docs.

Needham's findings have also been confirmed by other users running Firefox 99.0.1

Another user, Sergii Dymchenko, said strings like "But. But. But. But. But." triggered the same response. Some also noticed putting any of the terms like "Also, Therefore, And, Anyway, But, Who, Why, Besides, However," in the same format achieved the outcome.

A YCombinator HackerNews reader suspected the cause to be the "Show grammar suggestion" option in Google Docs.

A Google spokesperson confirmed the presence of the issue adding, "we're aware of this issue and the team is working on a fix."

How to recover your document

First thing first, turn off Show grammar suggestions so you do not run into issue by accident. In order to turn it off go to Tools and then into Spelling and grammar and untick Show grammar suggestions.

Now, if you already have a document that has been crushed, fear not because there is a workaround to access it. For some strange reason this bug does not manifest on Google Docs mobile app, so you can open the crushed document in the mobile app, delete words that have caused the bug and reopen the document on your desktop.

Until Google comes up with the solution this is currently the only way to address the issue.

New focus sessions in Windows 11
focus sessionWindows and Devices chief Panos Panay has revealed new focus sessions feature that will be in Windows 11 on his Twitter account today. He himself is referring to it as a game-changer especially with Spotify integration.

So what is a focus session?

From the video clip provided on Twitter, we can see that focus session users will be able to choose a specific task from the previously made task list, choose songs that will play in the background while the task is active, and set a timer for the chosen task with breaks. Maybe the best comparison and explanation would be a desktop google calendar task with music, basically, that’s it. A neat and good organizer inside your Windows 11 operating system. I think that this is generally a good idea and for sure it will find its audience.

Fix Windows Activation Error 0xC004F212
Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:
“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”
Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:
  • Go to Settings and then select Activation.
  • After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.
The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.
  • Extract the Windows 10 ISO files using an extractor.
  • Then browse to the folder you created and go to the sources folder.
  • From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:
[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Note: “xxxxx” is the KEY to your Windows version.
  • Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.
Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

Malware in Popular CCleaner

On September 18th, 2017, Cisco’s Talos announced that CCleaner, a popular utility with billions of worldwide users, had been compromised by hackers, and was used to unwittingly distribute hidden malware in its installer. Later in the day, Piriform, the publisher of CCleaner, confirmed the problem.

Undetected by all but 1 major antivirus including CCleaner’s own parent company, this occurred for over a month and impacted over 2.7 million users. Users of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 for 32-bit Windows are affected. These downloads were live on CCleaner’s official site from August 15th to September 12th, 2017. Anyone who downloaded the program during this time could be affected. The company claims that while the hackers set up the backdoor and many users were impacted, that the perpetrators have been arrested and that the malware never successfully performed its full task and compromised user’s PCs or sent out their data; in the wake of recent security breaches such as Equifax, users are understandably worried. Given the severity of the threat of hacking and data theft, users should take action immediately if they have CCleaner.

Technical Details of CCleaner Malware Injection

First reported by Talos, the malware, which was hidden in the CCleaner installer without the publisher noticing (despite them being owned by Avast, a massive Anti-virus company), modified a core program DLL file to evade detection, and creates several registry keys. Not only were these files not flagged by any major Anti-Virus, but they were also even digitally signed by Piriform via their Symantec certificate, meaning your PC and security program would likely whitelist and trust the malicious installer. The malware gathers personal information on a user’s PC, including IP address and running programs, and sends it to a remote server. In our testing, the program sent data to IP 216.126.225.148.

Restore Your PC (If Possible)

As of the publication of this article, there have been no assurances given that updating or even uninstalling CCleaner will remove the malware is installed. The only action thus far has been shutting down the remote server where user data was being sent has been shut down by authorities. For this reason, it is best to remove the underlying malware separately, as its presence represents a serious security threat. Unfortunately, as this could have been installed as far back as August 15th, 2017, your System Restore points may not go back that far, or even if they do, restoring to such an outdated point may cause unintended problems with other programs you use and potentially lost files and data. Manually backing up files and doing a full format or clean Windows installation would likely be successful in fully removing the malware, but is extremely time-consuming and can be difficult for many PC users. Unfortunately, this makes a PC Restore or format an unattainable option for many.

Update CCleaner to the Latest Version

While CCleaner has told users to update to the latest version of the program. Prior to doing so, we recommend fully uninstall CCleaner, ensuring you check its program files folders and registry keys, manually deleting any remnants, and then re-downloading the latest version from the official site and reinstalling clean.

Fix Windows Update error 0x80070003
If you are trying to run Windows Update but encountered an Error 0x80070003, read on as this post will guide you on how you can fix it. This kind of error in Windows Update can occur when you activate Windows Firewall or download from the Windows Store. This kind of error indicates that the Windows Update service or WUAUSERV is not started or that the Background Intelligent Transfer Service or BITS can’t be started. Aside from that, you can also encounter this error with the other Windows Update components. To fix the Windows Update error 0x80070003, you can try to run the built-in Windows Update troubleshooter or replace the old Configuration file named “Spupdsvc.exe”. You can also try to reset the Windows Update components or check the status of all the Windows Update-related services, as well as run a System File Checker scan.

Option 1 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error code 0x80070003. To run this troubleshooter, Refer to these steps:
  • Tap the Win + I keys to open Settings.
  • From there, click Update and Security and go to the Troubleshoot section.
  • Next, select Windows Update and click the “Run the troubleshooter” button and wait until it’s finished, and then try to run Windows Update again.

Option 2 – Try replacing the old Configuration file named “Spupdsvc.exe”

The next thing you can do to fix the Windows Update error is to replace the Spupdsvc.exe file. This is a process file that comes under the Microsoft Update RunOnce service. So when an update becomes available for your computer, the process responsible for performing the upgrade is notified. In addition, the RunOnce entry is also added to the registry for the spupdsvc.exe and this process is executed when your computer restarts and when you log on.
  • In the Start Search, type “command prompt” and from the search results, right-click on Command Prompt and select the “Run as administrator” option.
  • Next, execute this command to replace the old configuration of the Spupdsvc.exe file with a new one: c m d (remove spaces on CMD) /c ren %systemroot%System32Spupdsvc.exe Spupdsvc.old
  • After that, try to run Windows Updates again and check if the error is now gone.

Option 3 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.
  • Open the WinX Menu.
  • From there, open Command Prompt as admin.
  • Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv net start cryptSvc net start bits net start msiserver
  • After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
  • Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
  • Type each one of the following commands.
net start wuauserv net start cryptSvc net start bits net start msiserver
  • After that, exit Command Prompt and restart your computer.

Option 4 – Check the status of some Windows Update Services

  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “services.msc” in the field and hit Enter or click OK to open Services.
  • From the list of Services, look for the following services and make sure that their Startup type is as follows:
    • Windows Update – Manual (Triggered)
    • Background Intelligent Transfer Service – Manual
    • Cryptographic Services – Automatic
    • Workstation Service – Automatic
  • After that, check if the Service status of the listed services above are set to Running. If they’re not, click on the Start button to start these services and then check if the Windows Update error 0x80070003 is now fixed or not.

Option 5 – Run the System File Checker Scan

If manually resetting the Windows Update components didn’t work, you can run a System File Checker scan instead. It is a built-in command-line utility that replaces bad and corrupted system files with good system files that might be the cause why you’re getting the error when you try updating your computer. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Restart your computer.

Problem prevented document from being scanned
If an error suddenly pops up that states, “A problem prevented the document from being scanned” when you’re scanning a document in your computer, then you’ve come to the right place as this post will guide you on how exactly you can fix the problem. A lot of users have reported that they receive a two-layer error message when they try to scan their documents – the first screen throws an error message that says, “Error applying Settings to Driver” while the next error message states, “A problem prevented the document from being scanned”. As a result, the scanning won’t be completed which defeats the whole process of buying a printer with a scanner. As you can see the two error messages point to two different situations, while the other one is pointing at the driver, the second one points to the scanning problem. To resolve these issues, there are several suggestions you need to check such as follows:

Option 1 – Run the Printer Troubleshooter

One of the first basic troubleshooting you can perform to resolve the printer issue is running the Printer Troubleshooter. This built-in troubleshooter can detect and automatically fix the problem for you. To use it, follow these steps:
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
  • Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the USB Composite Device option and right-click on it, and select the Update Driver from the options.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try to reset the settings of the Printer or reinstall it

If none of the two options given above worked, you can try to either reset the printer settings or reinstall the printer so that it can go back to its default state. However, if it doesn’t work, you can try to uninstall the printer as well as its related drivers. To do so, follow these steps:
  • First, go to Settings > Devices > Printer and Scanners.
  • After that, select the printer and select the Remove Device option.
  • Once done, restart your computer and check again and see if the error is now fixed.

Option 4 – Try to modify the Registry settings for the Still Image devices

In case you don’t know, Windows has Registry settings for the Still Image devices like Scanners and Printers. And these devices have vendor-specific settings that if ended up getting corrupted or misconfigured then you will most likely encounter errors like “A problem prevented the document from being scanned”. Thus, to fix this error, you can try modifying the Still Image devices registry settings, and to do that, you need to follow the instructions below but before that, make sure that you create a System Restore Point first.
  • Once you’ve created a System Restore point, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and then hit Enter to open the Registry Editor.
  • Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStillImage
  • From there, right-click on the “StillImage” registry key and delete it.
  • After that, exit the Registry Editor and restart your computer.
  • Once your computer has restarted, Windows will recreate the settings of the Still Image devices back to their default settings.
