If you encounter an error saying, “Invalid file handle” when you try to rename, copy, delete a file or other operations in your Windows 10 computer, then read on as this post will guide you in what you can do to fix it. This kind of error pops up when the operating system tries to carry out an operation on a folder or file using the following words:
CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9
When you rename or create a folder or file using the reserved words given above, you could encounter an error that says, “The specified device name is invalid”. This occurs since these words are Windows system reserved words that you can’t use, unlike any other words. Thus, if you have a folder or file which contains any of the reserved words on another computer that runs a non-Windows operating system and you try to copy or rename it Windows, then it’s no wonder why you’re getting this error message.
In such cases, you can always click on the Skip button to stop the operation. However, if there are various folders or files, you can just use the Command Prompt to carry out the task. All it takes is a simple command that will get rid of the folder as well as the files in it. How? Refer to the instructions given below.
Step 1: Tap the Win + R keys to open the Run utility.
Step 2: Next, type “cmd” in the field and then tap Enter to open Command Prompt.
Step 3: After opening Command Prompt, execute the following command:
rd \.file-folder-path /S /Q
Note: The “rd” command will remove the directory or the folder while the “\.” command will select the current computer. The “/S” command, on the other hand, helps you in removing all the sub-directories and the files that are in the CON folder. The “/Q” command is not really mandatory since it helps you remove everything silently without any confirmation message. For example, if you have a folder named “CON” located on your Desktop, the path will be like this “C:/Users/<username>/Desktop/CON”. In this case, the command should be like this:
rd \.C:Users<username>DesktopCON /S /Q
However, if the error pops up for a whole different reason, you could use the following command instead to remove the reparse point extended functionality. Once you’ve entered the given command below, you should now be able to delete the file.
FSUTIL reparsepoint delete C:Users<username>DesktopFileName
DEL C:Users<username>DesktopFileName
Anxiety from all these digital threats lurking everywhere? An antivirus program can help put your mind at ease.
A virus is malicious software that can affect pretty much any device and does so in a variety of ways. Be it your computer, your phone or your smart lightbulb - as long as there’s access to the internet, malware can get to it.
How exactly does this kind of attack manifest itself? Well, there’s a wide variety of effects ranging from mild to severe. Among other things, they depend on which type of malware attacks your device - a virus, spyware, ransomware, adware or something else.
These are some of the things you can expect to happen:
It really can be the stuff of nightmares. So, if you want to sleep peacefully knowing that your devices are completely safe, you should definitely consider getting an antivirus.
P.S. don’t let its name fool you - an antivirus does indeed protect your devices against more than just viruses.
Antivirus software is designed to help you battle and ward off malware. Basically, it scans your device to detect any suspicious activity and offers tools to get rid of the culprit.
At first, antiviruses were developed to fight against viruses only, but nowadays they cover a lot more ground. Here are some of the biggest benefits of getting yourself a powerful defender.
Look, constant ads that pop up everywhere aren’t the absolute worst thing that can happen on your computer. If anything, they are annoying, like when you’re trying to sleep but that one fly in your room just won’t stop buzzing.
Now, there’s a free, well-established solution for that - installing an ad blocker. And we’re about a hundred and ten percent sure you’ve already done that on each and every browser you use.
However, “if I can’t see it, it doesn’t exist” isn’t the most ideal approach for your online safety. Ad blockers can’t block everything and they won’t protect you from potential adware. An antivirus on the other hand offers that layer of protection against malware snuck into pop-ups and spammy websites.
Hackers don’t target government institutions only. They’ll target regular people too if they have something to gain.
There are different types of hacking, such as phishing e-mails, transmission of malicious programs, credential reuse, denial of service and more. In any case, they take control of your device and hijack your data.
The good thing is that, as threats evolve, antiviruses evolve too and there are tons of quality programs on the market that can keep you secure for an affordable price.
When malware enters your device, it can target pretty much any file and get access to any and all data.
Installing an antivirus program will make sure that every single file, new or old, is monitored at all times, warning you against threats immediately. That way, you can make sure to react before your other files become infected and data is lost or stolen.
Another great thing for data protection is that the best antivirus software normally comes with a password manager, so no one can use malware to steal your passwords.
As we already stated, malicious attacks can be performed in many ways and malware comes in in different shapes an sizes, such as:
Nowadays, antivirus software is designed to fight against all of these types. That’s why more often than not we hear the term 'antivirus' used interchangeably with 'anti-malware,' like in this article.
You can’t keep your eyes on your kid every second of the day and you can’t protect them from everything. But at least you can limit their exposure to the threats they can encounter at every corner of the digital world.
An antivirus program will block harmful or suspicious websites and ads, which is great both for you and your children. To take it a step further, though, many such programs come with special parental controls and offer monitoring as well. It’s a great solution for keeping your kids safe online without sounding like the irritating, overbearing, controlling parent who “just doesn’t get it!”
There are definitely lots of different antivirus programs out there, both free and paid. We recommend you look for a paid option, since free ones are unfortunately a lot more susceptible to being compromised through malicious attacks.
Now, there are a few factors to consider when choosing the right software. If you use your PC for basic things then a basic antivirus will suffice. However, the more complex your use and the more sensitive the data you deal with, the stronger it needs to be.
It’s also crucial that you take into account the features it includes. As we already mentioned, some programs have additional security options. For example, depending on the package you select, Bitdefender provides:
Some are included in plans and some are separate products, so make sure to check out all the offers.
And don’t worry if you have multiple PCs or you’re looking for protection for your smartphone or tablet as well; Bitdefender has suitable solutions for your needs. Of course, you can also just pick their classic antivirus software if you’re not in need of advanced protection.
Another important point is how regularly the software is updated and enhanced. The more frequent the updates the better, as bugs can make the program more vulnerable. Other things we advise you consider are user-friendliness, impact on performance, reputation (user reviews especially) and, of course, price.
Fact is: anyone can be a malware victim. Don’t let it be you.
You can’t put a price on peace and security, so don’t be reluctant to pay for yours - especially since a lot of options out there are extremely affordable. Is $159.00 a year really too much to pay for cross-platform protection for up to 10 devices? We don’t think so.
Explore your options and protect your files and data before it’s too late.

When you upgrade your Windows 7 or Windows 8.1 system to Windows 10, you’ll undergo a phase called Out of Box Experience, or simply OOBE. This phase is intended to allow users to customize their Windows 10 experience, which includes defining personal settings, creating user accounts, and more. Some users reported having issues when creating their user account during the Out of Box Experience (OOBE) on Windows 10 upgrade. Some also reported issues about non-responsive behavior (Welcome Back) page.
Unfortunately, there’s no known cause for this error. However, some users reported that this occurs when:
Your Windows 10 upgrade will not be successful if you’re not able to create a user account or finish the Out of the Box (OOBE) phase of the installation. Here are some methods that will help you fix this manually.
Some users reported that waiting for about an hour and retrying the process again will solve this problem. It’s also recommended that you keep your computer in a ventilated place while you wait to retry the process.
This method has 2 requirements in order to work.
If you meet these two requirements, you can solve the error by following the steps below:
This method only applies if you’re a laptop user.
Instead of connecting to a Microsoft Account after the set-up, you might want to try creating a local account. To do this, follow the steps below:
If the steps above don’t work, you might want to try Startup repair.
In order to do this step, you need to have official Windows 10 ISO files.
After doing the steps above, there’s a chance you get an error message that says “installation cannot be completed in safe mode”. When you see this, just press Shift+F10. This will execute and open the command prompt of your computer.
From the command prompt, you can try and create a new user account.
For example, net user Username Password /add
The username here should be replaced with the account name you want to add, and the Password here should be replaced with the password you want to use for the account.
After replacing the username and password on the text, press the Enter button on your keyboard. You’ll know if the command is successful once you see the message, “The command completed successfully.”
You can now close the command prompt. Restart your computer and try to log in using the account you just created.
If all the above methods still don’t work, it might be best to try automated software to help you fix this problem.
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.
There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:
• Computer malware has infiltrated your device.
• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.
• When there are mismatched system files installed or system upgrading process failed or still incomplete.
• Premature unloading of Wbemprox.dll
• Newly installed third-party software is not compatible with the operating system.
• There are corrupted, outdated, or incorrectly configured device drivers.
• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.
• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.
In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately. However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.
