Even with the new Groove Music in Windows 10, a lot of users still prefer to use the old Windows Media Player. This isn’t surprising since Windows Media Player still remains to be one of the best players you can find. However, that does not mean that it is without flaws as it could still encounter some issues from time to time. One of the issues you might encounter when using the Windows Media Player is when you try to burn DVDs or CDs but end up failing due to an error that pops up that says, Windows Media Player cannot detect the length of the file. At the time of writing, it isn’t clear yet what the real cause of the error is. However, there are several fixes that are provided in this post for you to check out so you can resolve the problem. You can try to get rid of any unsupported files from the burning list or you could also try running the Windows Media Player troubleshooters. Aside from that, you could also try to drag and drop music or change the burning speed. For more details, refer to the following options.

Option 1 – Get rid of the unsupported files from the burning list

You must get rid of the unsupported files from the list of files to burn. This list can be found on the right-hand side of the Windows Media Player. One of the indications that a file is causing problems is when there is a white cross in a red circle next to the file. You can simply click on that icon to remove the file from the burning list. Once you’ve gotten rid of all the unsupported files, try to burn your files to the CD or disk once more.

Option 2 – Try running the Windows Media Player troubleshooters

The next thing you can do to fix the error is to run the built-in troubleshooters for the Windows Media Player. Windows 10 actually comes pre-packed with three troubleshooters designed for Windows Media Player. They can help in fixing the “Windows Media Player cannot detect the length of the file” error. To run these troubleshooters, simply tap the Win + R keys to open the Run dialog box and type “msdt.exe -id WindowsMediaPlayerConfigurationDiagnostic” for the Windows Media Player Settings troubleshooter or type “msdt.exe -id WindowsMediaPlayerLibraryDiagnostic” for the Windows Media Player Library troubleshooter, or type “msdt.exe -id WindowsMediaPlayerDVDDiagnostic” for the Windows Media Player DVD troubleshooter.

Option 3 – Try to drag and drop music

Another thing you can check out is to drag and drop all the tracks into the Windows Media Player before you burn them. All you have to do is open the folder where the tracks are located and highlight all of them and then drag them to the Windows Media Player. It should now be able to detect the length of each one of the tracks without any errors.

Option 4 – Try to change the burning speed

Since the burning speed is set to fastest by default, you can try to change the burning speed to resolve the problem. Just open the Options window and then go to the Burn tab. From there, select either Medium or Slow burning speed and save the changes made. Now try to burn your files to the CD or disk once again.

Hello and welcome to our user account notifications in Windows 10 tutorial where we will dive a little more into how you can control notification and behavior settings for your or someone else's user account in your Windows 10. If you are annoyed with confirmation windows each time you start a new application or install one please keep reading and I am sure you will find just the right setting for you. User account options are a little hidden and not so obvious, well at least not in Windows 10 compared to previous Windows versions. Since we will not be able to find them under typical and standard settings we will need to do few tricks in order to get to them.

Opening control panel

First thing is to press ⊞ WINDOWS + R on your keyboard so the run dialog window pops up on your desktop. Once run dialog is shown type in it control panel as shown in the picture and press OK If you have followed the steps precisely, you should be now in the control panel of Windows 10.

If you prefer some notifications try to find which of the remaining 3 settings best suit your needs. Once you are done and satisfied with your choice click on OK.

Distributed Component Object Model or DCOM is a module on Windows computers that allows computers to run programs over a network to another computer. It is a software component from Microsoft that allows COM objects to communicate with each other while that program is remotely running over the network. The COM Model is another extension of the DCOM model which both work together in order for the intended task to be executed. To make this module work, there are three components needed such as the Class Identifier or CLSID, the Programmatic Identifier or PROGID, and the Application Identifier or APPID. However, DCOM does not always work as expected as it could still encounter some errors. One of them is error 1084. Because of this error, the execution of programs in a remote computer on the network would be interrupted. So if you encounter the DCOM error 1084 when you try to start a service like running the DISM tool or in other scenarios on your Windows 10 computer, then this post could help you. Refer to the instructions given below to start troubleshooting the problem.

Option 1 – Try checking the status of DCOMLAUNCH Service or DCOM Server Process Launcher and its 3 dependencies

The DCOM Server Process Launcher service launches both COM and DCOM servers in response to object activation requests. This is why if this service is stopped or disabled, the programs that are using COM and DCOM won’t properly function. So you need to make sure that the DCOMLAUNCH service is running.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
• Next, check the following services:
  • DCOM Service Process Launcher
  • Background Tasks Infrastructure Service
  • Local Session Manager
  • Remote Procedure Call (RPC)
• Then right-click on each one of the services and click on their Properties.
• After that, select Automatic from the drop-down menu of Startup Type and make sure that all the aforementioned services are Running.
• Now click OK for each one of the services.

Option 2 – Troubleshoot the problem in a Clean Boot State

There are instances that some conflicting programs installed in your computer might be the one that’s causing DCOM error 1084. To identify which program is causing the problem, you need to put your computer in 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 3 – Try to use the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the DCOM error 1084. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the DCOM error is now fixed.

Option 4 – Reset your computer

• Tap the Win key or click on the Start button located in the Taskbar.
• Then click on the Power button at the bottom right portion of the screen.
• Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.

Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.

The Windows 10 Telemetry and Data Collection features are auto-enabled and they collect all sorts of user activity and sends it to Microsoft. Microsoft says that the data collected only enhances the overall user experience and Windows functionality better but the number of data breaches happening across the globe has forced users to be extra cautious about their data privacy. So naturally, from stronger passwords and other services management, it is only logical to turn off Windows data gathering. To do so:

• Press ⊞ WINDOWS + R to open the run dialog.
• In the Run dialog type: taskschd.msc
• Press CTRL + SHIFT + ENTER key combo to open Task Scheduler in admin mode.
• On the left pane, navigate to the: Task Scheduler Library > Microsoft > Windows > Customer Experience Improvement Program
• At the location, on the middle pane, right-click on the task named Consolidator and select Disable from the context menu...
• Repeat the process with all other tasks listed in the middle pane.
• Exit Task Scheduler.

If you are using your Google Chrome browser and suddenly notice a constant flickering after you’ve upgraded your Windows 10 computer, read on as this post will help you sort out the issue. A lot of users have reported this screen flickering issue in Chrome after having upgraded their devices to a recent Windows 10 build. The bizarre thing about this problem is that it only affects the Google Chrome browser and when it occurs, the Chrome browser will start to flash or flicker. According to users who experience the problem in Chrome, it seems to get worse when they try to play videos on YouTube or other streaming sites. To resolve this problem, many users tried to use Chrome in Incognito Mode, cleared the browser cache as well as cookies. They even tried resetting the browser settings and reinstall Chrome but nothing seems to work. Worry not though as there are still other options you can try to fix the problem and they’re easy ones so you’ll have no problem following them. The screen flickering problem in Chrome appears to be related to the Windows background and color settings as well as incompatible display drivers. This is why it is advised that you have both the video card drivers and Chrome browser updated to prevent the same problem from happening again. To get started troubleshooting the screen flickering issue in Chrome, refer to the following options.

Option 1 – Try modifying the background and colors settings

• Tap the Win + I keys to open the Settings app.
• From Settings, go to Personalization to load the Background Preferences and if this window does not appear, just select the Background option from the left side panel.
• Next, select a Solid Color as the new background from the drop-down menu.
• After that, check if the problem is fixed. This should be fixed especially if the one that’s causing screen flickering is the Windows automatic background switching.
• Once you’ve selected the Solid color as the background preference, go to the Colors tab under Personalization. This will open a new window and from there, check the box of the “Automatically pick an accent color from my background” option.
• Now close the Settings app and open Chrome again.

Option 2 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.

• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: If updating the Graphics driver didn’t fix the problem, you can also try to roll back to its previous version and see if that helps.

Option 3 – Try to disable the Hardware Acceleration

For better performance, Google Chrome uses the Hardware Acceleration by default. Unfortunately, there are just some cases when your hardware, GPU to be specific, might not be able to cope with the requirements, resulting in the black screen issue. And if this is your case, you should try to disable the hardware acceleration from your Google Chrome browser settings panel. To do so, follow the steps below.

• Open the Google Chrome settings page.
• Click on the Advanced button to get more options.
• Look for the option called “Use hardware acceleration when available” and then disable it by toggling the button to the left.
• After that, check if the screen flickering issue in Chrome is fixed.

Option 4 – Try to disable “Smooth Scrolling” in Chrome

Disabling “Smooth Scrolling” in Chrome might also help you fix the issue. To do so, follow these steps:

• Open Chrome and type “chrome://flags” and hit Enter.
• Next, look for a flag named “Smooth Scrolling”. You can scroll down until you find it or search it in the Search Flag bar. Note that Smooth Scrolling is enabled by default in the newer versions of Chrome.
• After that, select the drop-down menu and select Disabled.
• Then click on the “Relaunch Now” button.

A Word of Advice

For regular PC users, it is advisable to install an anti-virus and malware scanner and run it every time you use your computer. This helps you keep informed about the viruses or errors that your computer might be exposed to. And you can take timely actions before you experience file corruption and damage.

Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system. This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files. In this article, we will tackle both scenarios and provide you with solutions in both cases.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

Mozilla Firefox has introduced a new feature known as Restart with Windows which allows the browser to automatically start when your Windows 10 computer boots. This means that if you leave the Firefox browser opened while shutting down your computer, Firefox will re-open automatically along with the tabs that were opened right before you shut down your computer. Although some users may find this feature convenient, there are others who do not approve at all as it could be a nuisance. So if you’re one of the latter, then read on as this post will show you how you can disable the Restart with Windows feature in the Firefox browser on your Windows 10 computer. Refer to the instructions laid out below to get started.

• Step 1: Open Mozilla Firefox and if it’s opened already, just open a new tab and then type the following text in the address bar:

about:config

• Step 2: After typing the text given above, hit Enter and if a prompt with a warning message pops up, simply click on the “I accept the risk!” button to proceed.
• Step 3: Next, type “Restart” in the search filter which should display the following preference in the window:

“toolkit.winRegisterApplicationRestart”

• Step 4: After that, check for the preference value and then see if it’s set to true or not. If it is set to true, then it means that the Restart with Windows feature is enabled so obviously, to disable it, you need to set its value to false.
• Step 5: Now restart your computer without closing Firefox. After restarting your computer, you should no longer see Firefox starting automatically.

The Restart with Windows feature by default is disabled for most users. On the other hand, Mozilla will have this feature enabled as the default configuration in the coming weeks so it’s best that you now know what to do when that time comes since the newer versions of Mozilla Firefox are already being shipped with the Restart with Windows feature. However, if this post did not help you, then you might want to check if the feature has been added to the Startup folder, and from there, you can disable this startup program using the Task Manager > Startup tab.

In today's world setting up a LAN network or internet connection is no longer a daunting task that will require having a bachelor's degree in computer science nor a specialized technician. But even in the present-day environment issues and problems can occur. One of these problems is detecting or running a network at a slower 100MB speed instead of 1GB. Troubleshooting of this nature is somewhat more complex than your typical troubleshooting issue because several things including hardware could be involved in this particular problem but do not worry, we are here to back you up and guide you Setting up a home or small office network no longer requires a specialist technician to constantly monitor and optimize the LAN routers and connected PCs. As Windows networking has improved and new features have become available on the hardware, configuring a 1GB network should be as simple as connecting the LAN to a router that came with this capability. If however the network’s rated speed only gives 100MB, troubleshooting the issue is more complex. To find the problem, you’ll need to check the hardware devices, cable connections, and the software you are using to connect and manage the network.

Hardware checks

1. Check both connection jacks to see if it has any loose or frayed wires. If any of the wires are loose, it can be the cause of the performance issue. You should replace the cable if you discover damage to the connectors.
2. Inspect the entire length of the cable and check if the harness shows any clear signs of damage. A bent or damaged cable can reduce the amount of information it’s capable of transferring between the PC and LAN router. If you find any damage to the cable, replace it to restore your network speed.
3. Is the cable capable of transferring 1GB speeds? Different network cables support different network speeds. A Cat-5 cable will only provide 100MB transfers, while a Cat-5e or Cat-6 can support up to 10GB transfers. Check the cable’s labels to make sure you are using a Cat-5e or higher-rated data cable.

Now when the hardware issue is out of the way we can focus a little more on the software part.

Let's try the first easy solution, run Windows built-in troubleshooter

1. Click the Windows button and type Control Panel. Then select the top result.
2. If your Control Panel shows the Category View, change it to display Small Icons instead.
3. From the list of available applications, select Network and Sharing Center.
4. In your Network and Sharing Center, you can see the active network, set up a new network connection, troubleshoot problems, or change your adapter settings. Before making changes to your device properties, you can let Windows run a troubleshooter on your adapters to see if it can automatically fix your connection issues.
5. Click on Troubleshoot Problems from the Change Your Network Settings section.
6. In the Troubleshooter Application, scroll down and find the Network Adapter option.
7. Click on Run Troubleshooter to let Windows check your network adapter’s configuration for any issues.
8. Select the Ethernet Adapter you’re currently using from the list and click Next to proceed.
9. Wait for the process to complete and check the results. If Windows detects any issues, it will recommend a fix. However, if the configuration of your network adapters does not have any problems, you’ll see a message that Windows couldn’t detect any problems.
10. If there are any issues with the cable, the troubleshooter will detect the connection issue and request you replace the cable and connect it to your PC.
11. It can occur that even after inspecting the cable and you didn’t find any visible damage on the housing or connectors, it could still be faulty. Replace the cable with a new one and rerun the troubleshooter to see if the cable is working as required.

If the troubleshooter finished and you received a Windows Couldn’t Detect Any Issues result, you’ll need to verify your adapter’s speed settings.

1. In your Network and Sharing Center, select the Change Adapter Settings option from the left menu.
2. On the list of adapters, choose the one you’re using and click the Right Mouse Button to open the context menu.
3. Select Properties from the Context Menu to access your adapter’s settings.
4. On the Ethernet Properties window, you can enable or disable different features and install additional protocols. To change the device settings, click on Configure to continue.
5. This will open the Device Controller Properties window where you can check the status, make changes to the settings, find out information about the driver, or check historical events on the device. Select the Advanced tab to access the device settings.
6. On the Advanced tab, locate the Speed and Duplex setting.
7. The Auto-Negotiation option may cause network performance issues on certain Ethernet adapters and routers. The setting allows your adapter to change the speed settings according to the LAN configuration you connect to your PC. If you connect to different LAN networks regularly with different speeds, it can occur that the setting doesn’t update from 100MB to 1GB while switching.
8. Change the Value to match the network speed of the LAN you’re connecting to your PC and use the manual speed setting.
9. Click OK to apply the setting and test your network performance. If your adapter doesn’t have the 1GB setting available but you know the rating should go up to that speed, it could indicate that you aren’t using the right driver for the device.

If you don’t have the setting available or the device still only provides 100MB speeds after changing the Speed setting to a manual value, you may have to update the driver for the device.

1. On the Ethernet Properties Window, once again click on Configure to access the Device Properties Window. Then select the Driver Tab to access your driver details.
2. Select Update Driver from the available options.
3. On the Update Driver window, select the option to let Windows Search Automatically for Updated Driver Software.
4. Windows will connect to the internet and search for the latest drivers online. If a newer driver exists, Windows will download and install the driver for you. If you’re using the latest driver, Windows will inform you that no updated drivers are available.
