How to Stop Future Error Codes from Occurring

Though it is hard to predict when an error code will occur, each Windows 10 user can take precautionary steps to prevent other errors from occurring. This includes the following:

• Ensure you download software from reputable sources to avoid viruses and other forms of malware.
• Clean your registry often. The registry stores settings across all applications. Regular cleaning will your machine function more efficiently as it reduces the likelihood of issues such as crashes or system errors.

Every time a new drive or any storage device is connected to a Windows 10 computer, the operating system tends to allot a drive letter to it automatically. Not only that, as the OS also maps the location of the drive which helps it point the letter to the exact port location of the drive and serve requests from the user. As a result, it builds up a bit of cache as per the pattern in which the user uses the storage of the computer. This whole process is known as “Auto Mounting” which works for hard disks or optical drive readers that are connected using the SATA ports and even for USB drives that are connected using the USB ports. There are several ways you can enable or disable the Auto-Mount feature in Windows 10. You can do it using the MountVol tool or the Registry Editor or the Diskpart utility. Before you proceed, it is recommended that you create a System Restore point first so that you can always undo the changes you made in case anything goes wrong.

Option 1 – Enable or disable Auto Mounting via MountVol tool

In this option, you will be using the mountvol command in the Command Prompt. Refer to the steps below.

• Tap the Wins key once and type in “command prompt” in the field.
• From the search results, right-click on Command Prompt and select the “Run as administrator” option to run it with admin privileges.
• Next, type the following command and tap Enter to enable the Auto Mount feature:

mountvol /E

• On the other hand, if you want to disable the Auto Mount feature, type the following command instead:

mountvol /N

• After that, type the command below to remove all the previously assigned drive letters:

mountvol /R

• Finally, restart your computer.

Option 2 – Enable or disable Auto Mounting via Registry Editor

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and tap Enter to open the Registry Editor.
• After that, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesmountmgr
• Next, look for a DWORD named “NoAutoMount”. If you can’t find a DWORD with that name then simply create a new DWORD with the same name and make sure that the base is selected to Hexadecimal.
• Now double click on that DWORD and change its value to 0 if you want to enable it, otherwise, input 1 as its value to disable it.
• Restart your computer.

Option 3 – Enable or disable Auto Mounting via Diskpart utility

• Tap the Wins key once and type in “command prompt” in the field.
• From the search results, right-click on Command Prompt and select the “Run as administrator” option to run it with admin privileges.
• After opening Command Prompt as admin, type the following command and hit Enter to launch the Diskpart utility:

diskpart

• After that, a User Account Control prompt will appear. Just click on the Yes button.
• Next, type the following command and hit Enter:

automount

• Following the command you entered, you will an output that either says, “Automatic mounting of new volumes enabled” or “Automatic mounting of new volumes disabled” which means you can use it to check the status of Auto Mount.
• Now if you want to enable the Auto Mount feature, type the following command and tap Enter:

automount enable

• And if you want to disable the Auto Mount feature, just enter the following command:

automount disable

• To remove all the assigned letter and history of drives that were connected previously, type the following command:

automount scrub

• Finally, restart your computer.

Error code 0xc000021a - What is it?

Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.

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.

As you know, Windows 10 comes with the option to create Mobile Hotspot for other devices. This allows you to share your Ethernet connection. However, there are times when one of your devices might fail to reconnect to the mobile hotspot again. For instance, you moved out of the Wi-Fi range because you have somewhere to be and whatnot and when you’re back you find that you are now unable to reconnect to the Windows 10 Hotspot or the shared network. Although you can always restart the mobile hotspot to resolve the problem, however, it might only be a temporary fix. So in this post, you will be given options for a much better solution to the problem. This kind of problem seems unusual and does not occur that often. To fix it, you can try to set up DNS on your Windows 10 device and then configure the settings on the mobile device. It seems that what’s happening here is that the mobile device is unable to lock on to the Mobile Hotspot when the IP address changes for some reason.

Option 1 – Try changing the DNS settings on your laptop

In this option, you need to make sure that IPv4 and IPv6 are selected on your Ethernet connection. You also have to change the Preferred DNS server as well as the Alternate DNS server to 8.8.8.8 and 8.8.4.4, respectively. You also have to validate the settings before you exit just to ensure that you’ve entered everything correctly. After that, open Command Prompt and run the ipconfig command and then take note of the IP address, Gateway DNS 1 and DNS 2.

Option 2 – Try changing the Wi-Fi settings on your mobile device

This option should be mostly the same on all your mobile devices. And given that OEMs build their customization and skin, you might have to fiddle around a little to get the settings. Refer to the steps below to change the Wi-Fi settings:

• Go to the Settings of your mobile device and tap on Wi-Fi.
• Then click the Mobile Hotspot connection that you’ve created on your laptop.
• After that, input the password and tap the Advanced options.
• From there, tap on IP settings and select the Static option instead of DHCP.
• Now you have to enter the IP address, Gateway, DNS 1, and DNS 2 of the laptop you’ve taken note of earlier and that’s it.

Note: If you are already connected to the Mobile Hotspot, long press on the Wi-Fi network and select the Modify Network option and then follow the steps given above to change from DHCP to static. Once you’re done, your mobile device should now be able to connect to the Windows 10 Mobile Hotspot all the time.

If an error suddenly pops up that states, “A problem prevented the document from being scanned” when you’re scanning a document in your computer, then you’ve come to the right place as this post will guide you on how exactly you can fix the problem. A lot of users have reported that they receive a two-layer error message when they try to scan their documents – the first screen throws an error message that says, “Error applying Settings to Driver” while the next error message states, “A problem prevented the document from being scanned”. As a result, the scanning won’t be completed which defeats the whole process of buying a printer with a scanner. As you can see the two error messages point to two different situations, while the other one is pointing at the driver, the second one points to the scanning problem. To resolve these issues, there are several suggestions you need to check such as follows:

Option 1 – Run the Printer Troubleshooter

One of the first basic troubleshooting you can perform to resolve the printer issue is running the Printer Troubleshooter. This built-in troubleshooter can detect and automatically fix the problem for you. To use it, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the USB Composite Device option and right-click on it, and select the Update Driver from the options.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try to reset the settings of the Printer or reinstall it

If none of the two options given above worked, you can try to either reset the printer settings or reinstall the printer so that it can go back to its default state. However, if it doesn’t work, you can try to uninstall the printer as well as its related drivers. To do so, follow these steps:

• First, go to Settings > Devices > Printer and Scanners.
• After that, select the printer and select the Remove Device option.
• Once done, restart your computer and check again and see if the error is now fixed.

Option 4 – Try to modify the Registry settings for the Still Image devices

In case you don’t know, Windows has Registry settings for the Still Image devices like Scanners and Printers. And these devices have vendor-specific settings that if ended up getting corrupted or misconfigured then you will most likely encounter errors like “A problem prevented the document from being scanned”. Thus, to fix this error, you can try modifying the Still Image devices registry settings, and to do that, you need to follow the instructions below but before that, make sure that you create a System Restore Point first.

• Once you’ve created a System Restore point, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and then hit Enter to open the Registry Editor.
• Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStillImage
• From there, right-click on the “StillImage” registry key and delete it.
• After that, exit the Registry Editor and restart your computer.
• Once your computer has restarted, Windows will recreate the settings of the Still Image devices back to their default settings.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL
• SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)

In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers

There are times when you may encounter some glitches on your Google Chrome browser in your Windows 10 computer. One of these glitches is when the connection status of Chrome keeps on saying “Waiting for cache” which is displayed at the bottom-left side of the browser in the Status bar. At the time of writing, it isn’t clear yet what could be causing this problem. Although it is possible that it’s caused by browser cache, some extensions in the browser. On the other hand, it could also be caused by the browser profile or due to some fragmented files or that the SSD is occupied. Whatever the cause is, you can check out each one of the given options below to fix the problem.

Option 1 – Try clearing browser cache

There are times when some data in the browser is conflicting with the loading of the website and triggers some problems like “Waiting for cache”. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

Option 2 – Try to disable writing of Cache files to the SSD

You can also disable the writing of Cache files to the SSD to stop Google Chrome’s dependency on the SSD to gather all the cache files.

Option 3 – Delete the User Profile in Chrome

You can also try deleting the User Profile folder in Chrome. To do so, follow these steps:

• You need to first end every single process of Google Chrome. To do so, right-click on the Taskbar then select the Task Manager. And if the Task Manager is not responding, you can just use the Alt + Ctrl + Del keys and then select the Task Manager.
• After opening the Task Manager, under Processes, look for Google Chrome’s process which would most likely be named “chrome.exe”.
• Right-click on Google Chrome’s process and then select the End task option.
• Next, tap the Win + R keys to open the Run dialogue box.
• Then copy and paste “%USERPROFILE%AppDataLocalGoogleChromeUser Data” and hit Enter.
• From there, look for a folder named “Default folder” and then copy the folder to another drive as a backup.
• After creating a copy of the folder, delete the Default folder.
• Next, open Google Chrome again and go to Settings > Advanced > Reset.

Option 4 – Reset Chrome

Resetting Chrome can also help you fix the error. This means that you will be restoring its default settings, disabling all the extensions, add-ons, and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Option 5 – Try to clean reinstall Chrome

There are instances when programs leave files behind after you’ve uninstalled them and the same thing can happen to Chrome so before you reinstall Chrome, you have to make sure that you have deleted the User Data folder. To do so, refer to the following steps:

• Hit the Win + R keys to open the Run dialog box.
• Next, type “%LOCALAPPDATA%GoogleChromeUser Data” in the field and hit Enter to open the User Data folder.
• From there, rename the default folder and name it something else, e.g. “Default.old”.
