Fix Windows Update error 0xC1900209

The previous Windows versions all came with Microsoft's browser Internet Explorer. A lot of users love it because not only that it is easy to use. It is also very fast. Users didn’t have to worry about compatibility because it is almost always compatible with its Windows Version. When they introduced Windows 10, they changed the name of the browser from Internet Explorer to Microsoft Edge. It is faster and more user-friendly compared to its predecessors. But after the Creator Update, some experienced receiving the inet_e_resource_not_found error code. In contrary to what everyone expects, you actually don’t have to uninstall and reinstall the Microsoft Edge App. What you can do is reset the browser in your Apps & Features Settings in your Microsoft Settings.

To reset the browser you can follow the steps below:

1. Click on the Windows icon and go to settings.
2. Click on Apps and this will bring you to the Apps & Features page. Look for Microsoft Edge from the list of Apps and click on it.
3. Choose Advance Option
4. Scroll down then Under Reset, click on repair or reset. When you repair it will fix the existing problem but the data that caused the problem may still be present and can still cause problems. If you click on reset, it will delete all the cache and cookies that are installed in your browser but it will save your Favorites as well as your bookmarks.

Another way to resolve this is by disabling the feature TCP Fast Open on Microsoft Edge. To disable this, go ahead and follow the steps below:

1. Open the Microsoft Edge browser.
2. Type in about: flags on the Address (URL) bar.
3. Under Networking, uncheck the Enable TCP Fast Open.

If you find that your headphones are suddenly not working, read on as this post will help you sort out the problem. There could be several reasons why your headphone is malfunctioning, it could be due to an update you just installed, or it could also be due to incompatible operating system, drivers, and so on. Although updates are created to fix bugs on a computer, there are times when it also causes some issues in the computer. One of the issues it causes is the broken headphone. When this happens, the computer will stop playing any audio using the headphones. The problem, as pointed out, could be due to Windows Updates or incompatible or corrupted drivers in the system. To resolve this problem with the headphones, there are several fixes you can check out. Make sure that you follow each one of the given potential fixes below.

Option 1 – Try to set the headphone as the default device manually

There are times when you plug a headphone, it does not toggle the default audio device. Thus, to fix this issue, you have to set the default audio device to the headphones manually. To do that, follow these steps:

• First, right-click on the volume icon located on the system tray.
• Next, select the Open sound settings option to open the Sound section in the Windows 10 Settings app.
• After that, go to the Output section and select Headphones for the “Choose your output device” option. This should fix the problem for you.

Option 2 – Try to update, rollback or reinstall the Audio driver

If the glitch in your audio has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.

Option 3 – Try checking the status of the audio-related Windows Services

The Windows Services manages audio for all Windows-based programs and if this service is stopped, audio devices, as well as effects, will also be affected and if this service is disabled, any services that depend on it explicitly will fail to start. So you need to check the status of this service. How? Follow the steps below.

• Tap the Win + R to open the Run dialog box.
• Then type in “MSC” in the field and tap enter to open the Windows Service Manager.
• Next, navigate down to the Windows Audio Service and double-click on it to open Properties.
• After that, set the Startup Type to Automatic and then click on the Start button and if it has already started, stop it and then start it again.

Note: You should also make sure that the following Dependency Services are started and have Automatic Startup type:

1. Remote Procedure Call
2. Windows Audio Endpoint Builder

You should also start the Multimedia Class Scheduler and set it on Automatic if you have it in your system. The Multimedia Class Scheduler Service or MMCSS is a service in Windows that allows multimedia applications to get prioritized access to CPU for time-sensitive processing like the multimedia applications as well as prioritized disc access to make sure that the process does not lack data to process.

Option 4 – Try running the Playing Audio Troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the headphones. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 5– Try to rollback or install a newer Windows Update

As mentioned earlier, the issue with the headphones could be due to a Windows Update. Thus, to fix the problem, you can try to either roll back or install a newer Windows Update.

The System32 folder contains vital configuration and information that are essential to the operating system. It is located inside the “Windows” folder and it consists of important DLL files as well as executable files. You probably have noticed some errors that have the “System32” word in them but that does not necessarily mean that the System32 folder is the one that triggers them as these kinds of errors have only occurred when some important files are corrupted or missing. Some users recently reported that each time they start their computers, the System32 folder will automatically open up in the File Explorer. If you encounter the same problem, read on as this post will guide you on what to do to fix it. This kind of issue is most likely caused by service or application interference – it is possible that there is a third-party application installed in your computer or a Windows service that triggers the System32 to pop up during startup. It is also possible that this is a result of system modification. Thus, you need to identify the third-party program or restore your computer to its previous state.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

Option 2 – Perform System Restore

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys 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 and see if the System32 folder still pops up at startup or not.
