GoDaddy data breach compromised 1.2M accounts
A very serious data breach has happened to the unfortunate GoDaddy hosting service placing a little over 1.2 million accounts affected. Security breaches sadly are not a rare occurrence but this time it is a little different. GoDaddy breachEach time when the company is breached data is stolen and that places the company in a bad light usually because its user database has been compromised and people are concerned about their data being misused. This is very rational fear and concern but this time things are a little bit different than usual, why is that, you might ask? Well, as before mentioned GoDaddy is a hosting company and the vector of attack was aimed at the part where it is hosting WordPress. Attackers were able to get their hands on the sFTP credentials of customers on that server meaning that all of the websites are also been relieved of their user base as well. This potentially means that there is a high chance that all of the hosted web site's content is also compromised, meaning that your data could also be compromised even if you were not a GoDaddy customer, all you needed to do is to be a member of any site hosted on their platform. GoDaddy has reset WordPress passwords and private keys, so it’s already taken the steps required to stock the attacker from exploiting anything with the passwords obtained. The company is in the process of generating new SSL certificates for customers. Bad thing is that the attack used a compromised password to get into systems all the way back around September 6th, 2021, the breach was discovered on November 17th, 2021, which is more than a 2-month active time where the attacker could harvest tons of data. The outcome of this attack will be seen in the upcoming time, until then be safe, and Just in case change your passwords.

Attempt was made to reference a token
If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.
  • Open Command Prompt as admin from the WinX menu.
  • Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
    • exe /[DLL file]
    • exe [DLL file]
Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.
  • After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

  • First, you need to get the new DLL file from another computer with preferably the same file version number.
  • After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
    • x86: This PC > C:/Windows/System32
    • x64: This PC > C:/Windows/SysWOW64
  • Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
  • Now type the “regsvr32 ntdll.dll” command and hit Enter.
  • Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. 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 and hit Enter.
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.

Option 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.

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.

Software and hardware cleaning tips

They could slow down other applications like file explorer if they have extensions installed into them and can take RAM space with their background processes. If you are not using a particular application anymore or do not plan to use it soon it is always best practice to delete it from the system and thus removing all services and processes that go with it freeing so much-needed RAM and disc space.

Remove browser extensions you do not need

Browser extensions like applications can cause some issues with PC performance. if you spend a lot of time on the internet browser extensions can slow down browser and page loadings, they can make browsers take up more RAM memory and if they are outdated they could even present a serious security threat. Best practices are to keep only the extensions that you need all time, maybe some password managers or similar, extensions that you use on a daily basis, the rest should be uninstalled.

Remove things from the startup

Many services are booted along with Windows itself, some of them are crucial to the system even working, some not so. By eliminating not-needed services from the startup menu you will make sure that your boot times and overall performance of the system are in healthy form and that your PC is more responsive.

Organize files, folders, and desktop

The speeding of computer is not the only thing that you need to take care of, in order to be prepared and have maximum efficiency you will need to organize your files and folders as well. In a working environment, we often tend to save and place files all over the place, and in time they clog up desktop and hard drives. If the files are not well organized we will lose precious time trying to find anything that we need and require, so instead of wasting your time in locating files, why not organize them for easy and logical search so you can access them easily when needed.

Clean taskbar and start menu

Taskbar and start menu as well can be clogged with icons and non-organized application shortcuts and document shortcuts. Remove everything you do not need for that tidy and easily accessible access.

Sort bookmarks

It is very likely that you have plenty of bookmarks saved in our browser. It is also very likely that these bookmarks are not sorted and organized and now would be a great time to do it. Like files bookmarks also can cause you a lot of time loss if you need to find a specific one in a sea of many.

Run disc cleanup

Built-in disc cleanup utility will find temporary files, unused ones, and plenty of other junk on your hard drive. Now would be a great time to run it and get rid of junk files from your system.

Physically clean your computer

Now when we have taken care of the software part of our computer and system, it is time to clean up the computer itself. Unplug your computer and clean it, we will not go into details of this procedure, there is already an article on our site which deals with this part in detail so look it up if you need assistance with this part.

Clean your peripherals

Besides the computer for effective and pleasant work take care of your screen, keyboard, mouse, printer, etc. All of these devices need to be dust-free and clean if you expect them to behave on top of their game.

Fix Error 0x80200056 during Windows Update
You might have experienced a situation where your Windows computer was interrupted due to some battery issues or power failure. It could be that the upgrade process was interrupted because you’ve signed out of your computer or you restarted it by accident. In this case, you will most likely get a Windows Update or Upgrade error 0x80200056. If you are getting this error, read on as this post will guide you in fixing it. This kind of error pops up when the upgrade process was interrupted and could be caused by anything but the baseline here is that your computer was restarted accidentally or someone could have signed out your PC. To resolve the problem, here are some fixes you ought to try:

Option 1 – Try updating or upgrading your computer again

This is the basic thing to do since the process was suddenly interrupted. Just log in to your account and restart the Windows Update or Upgrade process but make sure that your internet connection is stable and that you don’t touch anything so as not to interrupt the upgrade/update process again.

Option 2 – Check if your PC is plugged in or if the battery is full

It is always best to update your computer always when you’re really sure that the power won’t fail. If you’re using a desktop computer, make sure that everything is plugged in. And if you’re using a laptop when this error occurred, make sure that its battery is at 100% but it’s better if you just plug it into power just in case as there are times when the Windows update or upgrade gets stuck for too long like for hours so it will really help if your device is connected to power.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update errors as well as the error 0x80200056. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 4 – Delete the contents in the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow 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 stop bits
  • After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
  • Next, got to the C:\Windows\Software\Distribution 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.
  • Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.
net start wuauserv net start bits
Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Option 5 – Try running the System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be causing the error 0x80200056. 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.

Option 6 – Run the Chkdsk utility to repair hard disk errors

You can also run the Chkdsk utility to resolve the Windows Update error 0x80200056. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.
  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
  • chkdsk C: /r /x
  • chkdsk C: /f

Option 7 – Run the DISM tool to repair the Windows Update client

The Windows update/upgrade error 0x80200056 might be caused by some issues in the Windows Update client so you need to run the DISM tool to repair it. Note that you have to use another computer or another Windows from a shared network to fix it.
