Here are some of the best and efficient methods to repair error 577 - no technical expertise is required.

Method 1 - Check and Update Device Drivers

If the problem is triggered by the outdated or corrupted driver for the device reporting the error then it is advisable to update the driver.

To do this, first, uninstall the corrupted driver and then reinstall the latest version.

For this simply click the start menu, go to the control panel and then click Performance and Maintenance, and then System. In the new window, you will then see a tab called Hardware and the Device Manager.

Double click on the device whose driver you need to uninstall. Click on the properties window with a tab marked driver. Then click on the driver you want to uninstall. To activate changes reboot your PC.

If the reason for error 577 is a viral infection, then simply install a powerful antivirus, run it to scan your entire PC. Remove all the viruses and malicious programs immediately to resolve.

If the issue still persists, then try method 3.

Method 3 - Repair the Registry

Sometimes registry corruption can be the underlying cause for error 577. The registry is the part that saves all activities performed on the system.

It stores both important and unnecessary files like junk files, cookies, and bad registry entries. If these files are not removed from the registry frequently, they accumulate and corrupt the registry which then generates system error codes.

Fix Chassis Intruded…Fatal Error…System Halted
When you encounter an error message that says, Chassis Intruded…Fatal Error…System Halted on your monitor then it indicates that the Chassis or the cabinet that holds the CPU, GPU, motherboard, and many more is open. It is a security feature offered by OEMs wherein a connector that is found in the motherboard can detect if the chassis component has been replaced or removed. There are a few OEMs that offer onboard speaker or PC chassis speaker which goes off in this kind of situation. Obviously, the problem has something to do with the hardware and in most cases, you have to put the jumper back on the motherboard with the pin-labeled chassis signal and ground. There are times when some OEMs offer a simple switch that is armed automatically when you properly close the chassis. Thus, you need to check if this switch has something to do with the error. If there is no switch or if it doesn’t resolve the issue, although you may be able to get into Windows with a warm boot, the normal Windows boot won’t really work unless you fix the problem. It is rather false positive and has something to do with the RTC RAM state or the BIOS. You might need to completely disable the Chassis intrusion feature to fix the error. Refer to the suggestions given below to try and fix the “Chassis Intruded, Fatal Error … System Halted” error.

Option 1 – Try to clear CMOS

You can easily clear CMOS by shorting two pins which can be found side by side on the motherboard. Keep in mind that it may vary from OEM to OEM although the basics are still the same to clear CMOS. In addition, you might also have to download the manual from the OEM’s website so that you’ll know its exact location.

Option 2 – Try booting into the BIOS

You can also try booting into the BIOS. All you have to do is tap either the DEL or F2 keys to get there. Note that everything will be set back to their default setting after you reset the CMOS.

Option 3 – Try disabling Chassis intrusion

In this option, you have to look for the Chassis intrusion feature in your BIOS. It might be located under security. From there, disable it and check if the problem’s fixed.

Option 4 – Try to reconfigure the BIOS

Once you have disabled the Chassis feature, you need to reconfigure the BIOS the way you expect it to be or to what it was before the reset.

Run Windows Updates from Command Line
As you know, one of the most highlighted features of Windows 10 is Windows Updates. It was offered to the customers as a service rather than a product with the release of Windows 10 under the scenario of Software as a Service which led to Windows Updates being set by default on Windows 10 and without an option for any users to disable it. Although not all users are happy with what Microsoft did, this is an ultimate step towards the greater good of all its customers since Windows Updates helps users in keeping their computers secured against all kinds of threats as well as provide them with the greatest and latest updates from Microsoft. So if you are one of those users who approved of the Windows Updates service, then read on as this post will guide you in running Windows Updates from Command Line either via Command Prompt or Windows PowerShell. For the complete set of instructions, refer to the options given below.

Option 1 – Run Windows Update via Command Prompt

Command Prompt in the Windows operating system exists for a very long time now compared to the comparatively new Windows PowerShell. That’s why it has similar capabilities to run Windows Updates. However, the highlighting point here is that you don’t have to download any module for Windows Updates. To get started running Windows Updates using Command Prompt, refer to the steps below.
  • First, type “cmd” in the Cortana search box, and from the search results, right-click on Command Prompt and select the Run as Administrator option to open it with Administrator privileges.
  • If a User Account or UAC prompt appears, just click on Yes to proceed.
  • Next, type in the commands listed below, and don’t forget to tap Enter right after you type each one of them.
    • UsoClient StartScan – use this command to start checking for updates.
    • UsoClient StartDownload – use this command to start downloading updates.
    • UsoClient StartInstall – use this command to start installing the downloaded updates.
    • UsoClient RestartDevice – use this command to restart your computer after you install.
    • UsoClient ScanInstallWait – use this command to check, download and install updates.
Note: Keep in mind that the commands in Command Prompt listed above are only meant for Windows 10. On the other hand, if you are using an older Windows version, you can try using the following commands instead:
  • wuauclt /detectnow – use this command to start checking for updates.
  • wuauclt /updatenow – use this command to start installing the updates detected.
  • wuauclt /detectnow /updatenow – use this command to check, download and install updates.

Option 2 – Run Windows Updates via Windows PowerShell

If you run Windows Updates in the Windows PowerShell, it will require you to install the Windows Update module manually. Hence, you have to get the Windows Updates downloaded and install Windows Updates.
  • Search for PowerShell in the Cortana search box and then run it with administrator privileges.
  • Once you’ve opened the Windows PowerShell, type the following command and hit Enter.
    • Install-Module PSWindowsUpdate – use this command to install the Windows Update module for Windows PowerShell.
    • Get-WindowsUpdate – use this command to connect to the servers of Windows Update and download the updates if found.
    • Install-WindowsUpdate – use this command to install the Windows Updates you’ve downloaded to your computer.

Mastodon test and review

What is Mastodon? Mastodon is an open-source microblogging network very similar to Twitter. You can make 500 characters post messages called toot (tweet), share videos or images, and follow other people. But unlike Twitter, Mastodon is decentralized, meaning the entire Mastodon is not run by a single company pulling all strings.

mastodon

Mastodon can be used directly in your web browser or through a mobile client on a smartphone or tablet. It includes features that seem copied from Twitter-like replies, boosts (retweets), favorites (loves), a timeline view, blocking, and voluntary content warnings that hide sensitive content.

Mastodon also has some great features that Twitter does not have like automated post deletion for the older post of a certain age, requiring approval for follows without restricting your account, and opting out of search engine indexing.

Currently, there are also no ads on Mastodon meaning no ad tracking or ad network surveillance.

How Does Mastodon Work?

Mastodon is a social media network made of nodes called servers or instances each running special software meaning anyone can run their own Mastodon instance (if they have a proper dedicated server). When you have your own instance it can be linked in the federation or remain private, so individuals or companies can have control over individual Mastodon servers.

The software itself is open source based on the social networking protocol ActivityPub which was developed by WWW Consortium.

While using Mastodon, people sign up for accounts with specific instances. Once logged in, you can view a local timeline (of posts from that instance only) or, if the instance is federated with others, see a federated timeline comprised of toots from people in other instances. Mastodon users can send messages to each other using their Mastodon account names that are similar to email addresses in that they feature the server address as well as the user name.

How to Fix Windows 10 Error 0x80070070

Error Code 0x80070070 - What is it?

Error code 0x80070070 can be presented when there is not enough drive space on the computer to install updates. It is possible to uninstall apps that are not often used, or you may delete or archive files that are no longer needed, you may even add on some removable storage space to free up the internal memory of the computer. The computer needs a significant amount of internal memory in order to be able to update the operating system properly. When the computer fails to have the amount of memory that is needed to perform the update, the error code 0x80070070 will be presented. If this error message is not resolved, your computer might be opened to other error messages, including error code 0x80072EE2.

Common symptoms include:

  • Windows cannot install updates properly.
  • You might not be able to install any additional programs or apps onto the computer.
  • When you check the memory of the computer, it may be very near its full capacity.

Solution

Restoro box imageError Causes

The Windows 10 upgrade error is caused by varying factors including a lack of computer space or resources, malware or virus infestation, or a clogged registry on the computer.  The error code 0x80070070 will present itself when there is not enough free space on the computer to perform the necessary updates on the computer. Too many apps or programs downloaded onto the computer, too many photos, or too much music may also contribute to the lack of storage space on the computer, thus contributing to the error, and the computer not being able to install the updates to the operating system properly.

Further Information and Manual Repair

There is not a lot of information regarding this error code, but there are a few methods to repair it when it does present itself. There are practical and manual steps that can be taken when trying to get the PC up and running. The primary way to solve this problem is to free up disk space and there are several ways to do this. Please do note that if these methods seem confusing or too complicated, do contact a Windows repair technician so that they may properly correct the problem. You will need to know for sure that it is error code 0x80070070 that you are dealing with so that these options are the best bet for fixing it.

Method One: Disk Cleanup

It is important to know how much space there is on the computer to start with prior to trying to free up any space. Use the free program on the computer called the Disk Cleanup tool. This will save time and free up some hard drive space while optimizing the computer to work better.

From the Start menu, browse to the Explore option, and then select This PC. Right-click on the C drive, and then select Properties. Select Disk cleanup. From here, select the options that you would like to clear. Make sure that the recycle bin is emptied of any temporary files or any error logs. Once done, select Okay.

Use this same process to clear the system files after an update from Windows, as they may still have files from the old operating system in place.

Go through your computer and remove any unwanted apps that are present. There are sure to be some that you do not use or do not want.

Follow these steps: From the Start menu, select Settings. Then, select System, Apps, and Features. When you have found the program that you would like to uninstall, select it and then select Uninstall. NOTE: some apps that are built into Windows do not have the capability to be uninstalled. Once you have selected Uninstall for the app or program, follow all directions that appear on the screen.

Method Three: Cloud Storage

If there are a lot of media, photos, documents, videos, and the like that are not used on a regular basis, try out cloud storage. These files will still be in your possession and will be able to be accessed from anywhere. There are many applications or websites that cater to this.

Method Four: External Storage Options

If none of the above methods work, add more storage. To acquire more storage, you can incorporate devices such as SD cards, USB flash drives, and even external hard drives.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Fix Windows Update error 0xC1900209
What is Windows Update Error 0xC1900209? Before you can install any updates on your Windows 10 computer, there are a lot of conditions that have to be fulfilled and one of these conditions is software compatibility. It is one of the important factors in installing Windows Updates. So if one of the software in your computer is not compatible with the new Windows Update for your OS, then the Windows 10 setup will not proceed and will block the installation of the new update. This both applies to the cumulative updates and feature updates. In such cases, you will get the following error message when you run Windows Update:
“0xC1900209, Incompatible software is blocking the upgrade process. Uninstall the application and try the upgrade again.”
This error message comes under the umbrella of the Windows 10 pre-upgrade validation using Setup.exe. And for you to identify the incompatible app, you need to grab a Windows 10 install image using the Windows Media Creation tool to download the suitable Windows 10 version and mount it. After that, execute the setup.exe file that’s located in the root folder of the Windows 10 install image. Once you execute the setup file, the upgrade wizard will give you a list of incompatible apps. Once you have determined which software is not compatible with the Windows Update, there are two options you can try to resolve the Windows Update error 0xC1900209 – you can either try to update the conflicting software or uninstall it. For more details, follow the given options below.

Option 1 – Try to update the conflicting software

If you are using an older version of the software that’s in conflict with the Windows Update, you might want to update it to its latest version and then try to apply the updates again to your Windows 10 computer. You can update the concerned software by visiting the official website of the software or any of its distribution sources. On the other hand, you can also use the Check for updates feature of that particular software if it’s available.

Option 2 – Try to uninstall the conflicting software

If updating the problematic program didn’t work, the next option you can try is to uninstall it. All you have to do is follow these steps to uninstall it successfully:
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “appwiz.cpl” in the field and tap Enter to open the Programs and Features in Control Panel.
  • Next, arrange the list of installed programs in the order of the installation date.
  • After that, look for the problematic program and right-click on it, and then select Uninstall.
  • Once the uninstallation process is done, restart your computer and see if the Windows Update error 0xC1900209 is fixed or not.

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.

The system found unauthorized changes
If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem. When you encounter this kind of problem on your computer, you will get the following error message on your screen:
“Secure Boot Violation The system found unauthorized changes on the firmware, operating system, or UEFI drivers. Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed. Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”
This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:
  • First, boot your computer into Windows 10.
  • Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
  • After that, go to the BIOS of your computer.
  • Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
  • Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Select the UEFI Firmware Settings which will take you to the BIOS.
  • From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
  • Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
  • Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.
  • Boot your computer into the Advanced Startup Options screen.
  • From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
  • Now select Troubleshoot > Advanced Options > Command Prompt.
  • After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.
  • After making the bootable drive, you need to plug it into your computer and then reboot.
  • Next, tap the F10 or Esc key to open the boot options.
  • Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

Is it wise to keep old electronics

Hello all the wonderful people and welcome to our new article where we take a little different turn than usual and discuss why keeping old electronics around the house is not such a good idea. We all have some drawer or in some bag around the house and in the end of the day if that electronic has battery inside it is probably not the smart thing to keep it.

So naturally, the question comes why it is a bad idea to have old electronics with batteries in them? Well unlike a battery failure with, say, some AA batteries jammed in the back of an old toy, the risk with a lithium-ion battery failing isn’t just some leaking and corrosion in the battery compartment, it’s a potential fire as the battery swells up and the gases (combined with the stored energy) turn the battery into a potential fire hazard.

Good thing is that the battery will not explode just like that, it will swallow over time and get bigger and bigger until the breaking point is reached and all the fire breaks lose. So if by any chance you have some old gadgets lying around you can check up on them and see if has swelling process started, if yes, dispose properly of that piece of the old device immediately.

How to keep old electronics

If you’re not ready to get rid of the gadget then it’s best to charge it properly for storage. Proper charging keeps the battery cells and circuits in optimum health.

While recommendations vary by manufacturer and application, the general consensus is that lithium-ion batteries should be charged to approximately 40%. (Some manufacturers recommend charging 50% or 60% instead.)

Really, the important part here isn’t the exact percentage. What’s important is ensuring that the battery is charged to roughly half capacity and not stored with a completely discharged or completely full battery.

Discharge rates on lithium-ion batteries in completely powered-off devices are very slow, but you should still plan to top off the charge every 12-18 months or so to keep it around 50%.

If you wanted to go above and beyond, a metal storage container with a snug lid on a basement shelf with a desiccant pack inside to control the moisture would offer optimum conditions.
