Windows Defender error code 0x80073afc

When you upgrade or update your Windows 10 computer but you suddenly got Error 0x8024a206 while trying to install the updates, it is due to a rouge update that was downloaded or because of some corrupted component in Windows. In case you don’t know, any file downloaded by Windows is verified for its integrity and if the files don’t pass the integrity test, then Error 0x8024a206 will most likely pop up during the Windows update or upgrade.

Option 1 – Reset the Windows Update components to the default

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush 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. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• 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, and then try to run Windows Update once more.

Option 2 – Re-register DLLs related to Windows Update

DLL files, also known as Dynamic Link Library, are parts of applications that are separated from the core program so that they can be used again as well as independently be updated. The DLL files are loaded into memory and then used. Note that they have to be registered with Windows so they can be loaded. So if they’re not, the main program will fail. And this is the same with the DLL files related to the Windows Update. Thus, you need to register them in order to resolve Error 0x8024a206.

• In the Cortana search box, type “command prompt”.
• From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that execute the commands listed below one after the other and don’t forget to hit Enter right after you key in each one of them.
  • regsvr32 JSCRIPT.DLL
  • regsvr32 MSXML3.DLL
  • regsvr32 WUPS2.DLL
  • regsvr32 WUPS.DLL
  • regsvr32 WUAUENG.DLL
  • regsvr32 WUAPI.DLL
  • regsvr32 WUCLTUX.DLL
  • regsvr32 WUWEBV.DLL

Note: You also have the option to run the commands together via a batch file. Simply create a batch file by copying all the commands in a notepad and then save it as “WURegisterDLL.bat”. After that, run the batch file and it will execute the commands all at the same time. Then you have to restart your computer and see if it has fixed the Error 0x8024a206.

Option 3 – Run the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Error 0x8024a206. 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. 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 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update Error 0x8024a206. 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. After that, follow the next on-screen instructions and you should be good to go.

When you get the error information, "The Software Can Not Begin Because MSVCR100.Dll Is Missing", what this implies is that the Computer will be lacking the  MS Visual C++ 2010 libraries. The malfunction is rather frequent throughout installations. It doesn't matter the number of times you try to reinstall the program. The malfunction can happen whether you've been utilizing your pc for many years, or it's really a recent one.

Solution

Error Causes

a) Missing MSVCR100.DLL: As the problem message indicates, you get this information mainly because MSVCR100.DLL is completely missing. b) Broken MSVCR100.DLL: When the msvcr100.dll is broken, you will also get the same error, suggesting the software won't start. The thing you need to understand is the fact that MSVCR100.DLL is playing an important role in the application referred to as MS Visual C++ 2010 Redistributable Package. Without the MS Visual C++ 2010 Redistributable Package, any software that you simply make an effort to install won't start. You could possibly complete installing it by pursuing proper installation procedures, and then end up getting the "The Software Can Not Begin Because MSVCR100.Dll Is Missing" error.

Further Information and Manual Repair

If you get the "The Software Can Not Begin Because MSVCR100.Dll Is Missing" error information on an effective setup of any software, you shouldn't worry. You can really repair the issue and commence your recently installed software without any more hassle. Start by checking whether you presently use 64-bit or 32-bit Windows. Visit the start button, in case you use Winxp. Type winver. On the window that appears, click Run, subsequently push enter. Head to Start, in case you use both Win7 or Vista. Subsequently, click on the search box and type “Computer”. Right-click windows and subsequently click on Properties. Under Windows Edition, you'll find whether your Windows is 64-bit or 32-bit. Search for the correct variation of MS Visual C++ 2010 Redistributable Package, as soon as you discover whether your Windows is 64-bit or 32-bit. Down load the x86 variant of MS Visual C++ Redistributable Package if your version is 32-bit and you must obtain the x64 variant of MS Visual C++, for those who own a-64-bit version of Windows Operating System. You must never obtain MS Visual C++ 2010 Redistributable Package from third-party websites. This is because Microsoft doesn't charge a cent for the files. The files are openly and easily available on Microsoft. These files come in many different variants. Consequently, select what's suitable for your own Computer with regards to the version of Windows which you operate.

• Never pick the edition of MS Visual C++ 2010 Redistributable Package that's not compatible or appropriate to your Windows Operating System.

Make use of the release date, when installing MS Visual C++ 2010 Redistributable Package. You might also look out for Service Pack 1 and obtain it for your Windows. Service Pack 1 only ensures that you simply obtain the latest edition. As soon as you end installing the most up-to-date version of MS Visual C++ 2010 Redistributable Package as demonstrated above, reboot your computer and you'll not have to worry about getting the annoying"The Software Can Not Begin Because MSVCR100.Dll Is Missing" error message anymore.

To turn password login in Windows 10 you will need approximately one minute of your time. So let's do it fast and efficient Press ⊞ WINDOWS + X to open the secret menu Click on command prompt (admin) Type in command prompt following:

powercfg /SETDCVALUEINDEX SCHEME_CURRENT SUB_NONE CONSOLELOCK 0

press ENTER

powercfg /SETACVALUEINDEX SCHEME_CURRENT SUB_NONE CONSOLELOCK 0

press ENTER And you are done! Next time when you open your laptop from sleep you will no longer need to type in the password.

If the Sleep option is missing from the Power Menu then this could be caused by the power settings, local group policy configuration, etc. in your computer. Based on the reports of users who experience the same problem, the issue occurred after they’ve updated or upgraded their Windows 10 computers. As you know, the sleep mode is quite useful in certain cases and is utilized by most users. If you put your computer in sleep mode, it actually minimizes the power usage of your computer while at the same time keeps your current session running. So if sleep mode is suddenly missing, then that could be a problem but worry not for this post will give you possible fixes to resolve the issue. Make sure to follow each one of them carefully to achieve good results.

Option 1 – Check the Power settings

As mentioned, one of the reasons why the Sleep option is missing could be the power settings in your computer. To check this possibility, make sure that you’ve enabled the sleep mode in the Power options setting window. How? Refer to these steps:

• First, go to the Start menu, and from there open Control Panel.
• Next, set the View by Large icons and select the Power Options.
• After that, click on the “Choose what the power buttons do” option on the left-hand side.
• Then click on the “Change settings that are currently unavailable” option and make sure that Sleep is checked under the Shutdown settings.
• Afterward, click on Save changes.

Option 2 – Modify the Local Group Policy

If the Power setting isn’t the cause of the problem, then you might want to check the Local Group Policy and modify it. There is a dedicated policy for showing the sleep option in the power menu and if this policy is disabled, then it’s no wonder why you don’t see the sleep option in the power menu. To change this policy, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to this path: Computer Configuration -> Administrative Templates -> Windows Components -> File Explorer
• Look for the “Show sleep in the power options menu” option from the right-hand side pane and double click on it.
• Now change it to Enabled and click on the Apply and OK buttons to save the changes made and restart your computer.

Option 3 – Try to turn on Standby

Standby, also known as InstantGo, is a feature in Windows 8 and 10 that allows users to maintain network connectivity after a computer has been put into sleep mode. Thus, if this feature is disabled, it can cause the Sleep option to disappear from the power menu. To turn it on, follow these steps:

• Tap the Win + R keys to open Run.
• And type “Regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPower
• From this path, look for the “CsEnabled” key on the right-hand side of the pane and double-click on it.
• Set its value to “1” and click OK to save the changes made.
• Now reboot your PC.

Note: If you were not able to find the CsEnabled key, then this indicates that your computer does not support the Standby feature. And if that’s the case, proceed to the next given option below.

Option 4 – Try to install a Video Card driver

On the other hand, some users reported that the problem was caused by the video card driver. And if your computer lacks the video adapter driver, it can also cause the same problem. Windows 10 typically install the video card driver on its own, however, there are rare cases when it doesn’t which is why you have to do it yourself manually. All you have to do is go to your manufacturer’s website and look for the video card driver, download it and then install it. Once you’ve installed the video card driver, reboot your computer and check if it has fixed the problem.

If you are trying to save a file in a PDF format on your Windows 10 computer but then the PDF text content in an Adobe file suddenly disappears, then read on. This post will give you more insight into this issue. This kind of issue is rare and mostly occurs in forms that you can fill upon. In such a case, the text you enter in the form vanishes right after you click the Save button. One of the benefits of working with PDF files is that it has the ability to compress high-quality files to relatively small file sizes. This is really useful especially when you are saving hard drive space and you’re working with limited storage resources. However, these files can contain layered content if they are created from layered documents using applications like Adobe InDesign. Consequently, a single page of the PDF file can contain different layers with different content. So if you try to save or print a PDF file that contains layered content, the elements will disappear from the PDF. To resolve this issue, you can try to merge or flatten the file since it will help keep the changes in the PDF file. On the other hand, you can no longer make any alterations or form data once you flatten the file. Another thing to keep in mind is that merging or flattening the file can’t be undone so you might want to save another copy of the file before you proceed.

Option 1 – Print to PDF

• First, you have to open the desired PDF file and tap the Ctrl + P keys to open the Print dialog box.
• After that, select the “Microsoft Print to PDF” option as the printer.
• Once the action is confirmed, it will regenerate another version of the PDF file with the default settings and merge all the existing layers into a single layer.
• On the other hand, you can also click on the “File” menu of the PDF file and select Print.
• From there, click on the Print button and select “PostScript (*.ps)” as the “Save as” type to save a PostScript copy of the original PDF file.
• Once you’re done, double click on the .ps file to open the file in the Adobe Distiller which will flatten the file automatically and convert it to a PDF file with only one visible layer.

Option 2 – Save the PDF file as an Optimized PDF file

If you are using the Acrobat Reader Pro version such as the Acrobat Pro, Foxit, and so on, you can try to flatten the layers by saving the PDF file as an Optimized PDF file. Refer to these steps to do so:

• Select File > Save as > Optimized PDF.
• Next, select the Transparency checkbox from the Settings window that opens.
• Then click on the Save button to apply and save the changes made. After that, the PDF text content should not disappear when you try to save a file on your Windows 10 computer.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.
