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.

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.

Windows Setup in Continuous Reboot Loop – What is it?

After 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.

Solution

Error Causes

When 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.

Further Information and Manual Repair

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.

Method One: Check For Windows Update

Microsoft Windows released an updated fix for the Windows setup in continuous reboot loop problem. You can try fixing the issue through Windows Update.

1. Open Settings
2. Go to Update & Security
3. Select Windows Update then choose Check for updates

At this point, an additional update will be installed and downloaded to your operating system to resolve the continuous reboot loop problem.

Method Two: Eliminate Bad Registry Entry

Before KB3081424 attempts to install again, you can try doing this solution:

1. Click on the Start menu then type regedit
2. Once the window opens, go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
3. Create a backup for your registry key (since this process is a bit risky). Select ProfileList then click on File and Export then choose your backup name.
4. From the ProfileList IDs, remove anything with ProfileImagePath in it.
5. Close Regedit then reboot. By this time, the KB3081424 should properly install.

Method Three: Perform A Startup Repair

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.

1. Ensure that all unnecessary devices are disconnected from your computer as your computer might detect them.
2. If you are connected to a network, you need to disconnect from this as well.
3. On a working computer, download the Windows 10 ISO then you can perform a startup repair.
4. Boot your computer from the Windows 10 DVD.

To change your BIOS option to boot from the Windows 10 DVD, follow these steps:

1. Boot your computer then press the F2 function key to enter setup.

NOTE: You must do this quickly since the BIOS loads rapidly.

2. Once you’re inside the BIOS, navigate to the Boot Configuration screen. On this screen, you’ll be able to change the first device to be loaded.
3. Go to Removable Devices then hit Enter. Removable devices could either be a thumb drive or DVD. Select DVD to put it at the top and be the first boot device.
4. Save your changes by pressing on the F10 function key. A setup confirmation box will appear with a message Save configuration changes and exit now. Select Yes.
5. Exit BIOS by pressing on the ESC key. You should be prompted to boot from the Windows 10 DVD at this point.

If you're not able to execute the aforementioned processes on your own, get help or download and install a powerful system optimizer to assist with the windows continuous reboot loop process and other Windows 10 error messages.

Error Code0x80070426 - What is it?

When Windows evolved into Windows 10, the program known as Windows Security Essentials is no longer. It is now the program known as Windows Defender. When a computer is upgraded from a previous version of Windows up to Windows 10, the Windows Defender takes over and will replace the Security Essentials. In a small percentage of Windows 10 upgrades, something will go wrong and the new program will fail to replace Security Essentials. The result will be that the operating system has both of the programs installed. In this case, Windows Defender will not offer any protection and Security Essentials will not be able to defend either. This error code will also present itself when the Windows Mail App in Windows 10 fail to retrieve and sync email from the user's account.

Common symptoms include:

• There will be an error message that says: “An error has occurred in the program initialization. If this problem does continue, contact your System Admin. Error code 0x80070426.”
• The computer will be left completely vulnerable to spyware and viruses.
• The Windows Mail App will not be able to retrieve mail and will not sync with the PC user's mail.
• The user can be doing anything on their computer and the error code will show up unprompted.
• The computer will lock up, become slow, crash, or even freeze when dealing with error code 0x80070426.
• The programs from an older version of Windows do not replace the newer version from Windows 10.

Solution

Error Causes

Error code 0x80070426 will present itself when a PC user has upgraded their OS from a previous version of Windows to the new Windows 10 version. When this happens, a small portion of users will experience the disconnect between older versions of specific programs, namely the virus protection. When the previous version of the program under a different name is not completely removed and the new virus protection program is installed, the programs will cancel each other out and collectively offer no protection.

This error code may also be found when Windows 10 tries to sync the user's email with the Windows Mail App.

Further Information and Manual Repair

There are a few methods to repair this problem. It should be noted that should anyone feel that the instructions are too complicated, they should contact a Windows repair technician to ensure that the error is fixed properly.

Method One: Uninstall Microsoft Essentials

Hold down the Windows Key and press R. Type in taskmgr into the run dialogue. You should locate the Windows Defender Service (this may show up as Windefend). Right-click on it and then choose Stop.

This will stop the program, but the program will start back up automatically when the computer restarts. While this program is stopped, uninstall Essentials.

To do this: go to Control Panel, Programs, and Features, Uninstall a Program. Alternately, you may hold down the Windows Key and press R, type in appwiz.cpl, click OK, and then locate Microsoft Essentials. Uninstall it, and then restart your computer.

After this is done, go to Settings, Update, and Security. Choose Windows Defender and ensure that Real-time protection is on. Refer back to the Task Manager, Services. Make sure that Defender service is on and running.

Method Two: If the problem occurs in the Windows Mail App

When error code 0x80070426 presents itself in the form of an error with the Mail app, it may be necessary to run an SFC scan.

Right-click on the Start menu or Windows icon, and select Command prompt. The command prompt may be navigated by using shortcut keys Win and X and then select it.

Run the command prompt and then type in sfc /scannow and then press enter. The SFC scan will be run, and be careful not to abort the process before it has finished. This will scan for any files that are lost or corrupt on the PC.

If the scan has found any corrupt files, type in this code and then hit Enter: findstr /c:”[SR]” %windir%LogsCBSCBS.log >”%userprofile%Desktopsfcdetails.txt.

To skip the repair of corrupt or missing files, type in: Dism /Online /Cleanup-Image /RestoreHealth. The details of the scan can be found on the sfcdetails.txt file that will be on the desktop.
