Code 33 - What is it?

Code 33 is a typical Device Manager error. This error code occurs when Windows is unable to start a device that you are trying to use on your PC. The error code 33 is usually displayed in the following format:

“Windows cannot determine which resources are required for this device. Code 33”

Solution

Error Causes

Error code 33 may be triggered due to two reasons. One reason can be the translator's failure to find the correct resource for the device driver.

And since this error code is associated with the Device Manager, another reason can be an outdated or corrupted device driver. In most cases, the underlying problem for Device Manager error code is outdated/corrupted drivers.

The good news is that Device Manager error code 33 is not detrimental. However, if the error is not resolved timely, it can lower the functionality and the performance of your PC. You may not be able to use the hardware device.

While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

Option 3 – Bypass the Certificate Revocation Check

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.

• In the search box of your browser, type “internet options” and open it once it appears.
• After that, go to the Advanced tab and navigate to the Security subheading.
• Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
• Now restart your computer. Upon the next startup, try opening the website again. This time, your browser will stop checking it for certificate issues. However, it’s not safe to leave those options unchecked so make sure that once the website’s SSL certificate is fixed or once you no longer have to visit that website, you recheck those options.

As you know, the Graphics Card in a computer is one of the important components in an operating system as they are responsible for rendering various objects in your computer. However, there are cases when the performance of this rendering can degrade and your computer can trigger a VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen of Death error instead. The VIDEO_SCHEDULER_INTERNAL_ERROR bug check has a value of 0x00000119 which means that the video scheduler has detected a fatal violation in your computer. Before you troubleshoot the problem, you might want to perform System Restore first as it might help you fix the Stop error. To perform System Restore, refer to these steps:

• 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 Stop error is fixed or not.

If the VIDEO_SCHEDULER_INTERNAL_ERROR BSOD error is still not fixed after System Restore, then follow the given options below to further troubleshoot the problem.

Option 1 – Try to manually check the Graphics Card hardware

You might also want to check the physical status of your Graphics card and you can do this by disconnecting the Graphics card or any other external device connected to your computer. Once you’ve removed the external device, check it for any damages. If there’s none, connect it back to your computer and check if the VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen error is fixed or not.

Option 2 – Try removing hardware or drivers that you’ve installed recently

If you have recently installed some hardware or drivers, you might want to disable or remove them since external devices are proven to be one of the factors that trigger Blue Screen errors like VIDEO_SCHEDULER_INTERNAL_ERROR. All you have to do is physically disconnect any external devices that are connected to your computer and then check if it fixes the BSOD error or not.

Option 3 – Try to rollback, update, or disable the Graphics card drivers

Since the VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen error has something to do with Graphics card drivers, you can either roll back, update or disable them depending on your preference in order to resolve the error.

• 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.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to 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.

Option 4 – Uninstall any faulty drivers

You can also uninstall any faulty drivers via Device Manager. How? Refer to these steps:

• Tap the Win + R keys to launch the Run dialog box.
• Then type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• From there, look for any faulty drivers. You can identify them easily as they will be marked with a yellow exclamation point. And then check which entries would not affect the normal functioning of your PC.
• Now click on the entries of every faulty driver and click on the Uninstall option.
• Once you’ve uninstalled them, restart your computer to allow your computer to reinstall the faulty drivers you’ve just removed.

Option 5 – Run System File Checker at boot time

• Once you get to the Welcome Screen part, click on Next.
• Afterward, click on the Repair your computer option located on the bottom-left part of the window.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• After opening Command Prompt, type the “sfc /scannow” command and hit Enter to run the System File Checker scan.
• Wait until the process is completed and type “exit” to close Command Prompt and then restart your computer to successfully apply the changes made.

Option 6 – Try to run the Blue Screen Troubleshooter

As you know, the Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like the VIDEO_SCHEDULER_INTERNAL_ERROR error. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

If you were trying to copy, move modify or delete a folder or a file in your computer but you’re not able to do so and encountered an error instead that says, “Could not find this item, This is no longer located in <path>, Verify the item’s location and try again”, then you’ve come to the right place as this post will guide you on how you can fix this error. You can encounter this error when you delete, rename, open or copy a certain file which is often created by third-party software and lacks important information like file format, and so on. Although you can see these files in File Explorer, you might not be able to perform some operations in them. To fix this problem, you need to check out the given suggestions below.

Option 1 – Try to rename the file via Command Prompt

If you were trying to rename the file but unable to do so, you can achieve that by executing a command in Command Prompt. Make sure to follow the steps carefully.

• Type in “Command Prompt” In the Start menu to search for it or you could also click the search button right next to the Start menu and then right-click on the related result and select the option “Run as administrator” to open Command Prompt with admin privileges.
• Next, type in “cd” followed by the path where the file is located with this format – “C:/Folder1/Folder2/Folder3”. However, you have to omit the problematic file this time. To put it simply, the last folder in the command must be the folder where the file is located.
• After inputting the command, press Enter on your keyboard and then use the set of commands given below. Note that each command is a new line so you need to tap Enter after copying each line.
  • DIR /A /X /P
  • RENAME (the current name of the problematic file) (a non-problematic name)
  • EXIT

Note: Make sure that you only input the current name and the new name separated by a space. You must not write the brackets in the command. If everything goes well, you will now be able to operate the file like you used to before.

Option 2 – Try to delete the file using Command Prompt

On the other hand, if you were trying to delete the file instead of renaming it, you can execute another command in Command Prompt.

• Open Command Prompt with admin privileges like what you did earlier.
• Once you’ve opened Command Prompt, copy and paste the command given below and tap Entre after you do so. You also have to make sure that you key in the correct path where the file is located as well as its name.

rd /s \?X:badfolderpath

Note: In the command above, “X” is the placeholder letter so you must input the letter that corresponds to the drive’s letter where the file is located.

• After that, you will see the “Operation completed successfully” message on your screen. If you don’t, check if you’ve really inputted the correct location of the file or its name.

Option 3 – Delete the file without any extension

If the file you were trying to delete does not have an extension, this means that Windows does not know what to do with this file which is why it’s throwing an error message. The best thing to do in such cases is to delete the file especially if it takes up a lot of memory. To delete these kinds of files, here’s what you have to do:

• Follow the first two steps from the previous option above so you can navigate to the location of the file accurately just be careful in inputting the folders.
• Don’t forget to tap Enter right after each command and then use the next command below so you can delete the affected file which has no extension:

del *.*

• After you’re done, open the File Explorer and then check if the file is now deleted or not.

A couple of Windows 10 users have reported an error on domain-connected systems when they tried accessing their computer systems remotely. This occurs when the network level authentication or NLA is enabled on the computer. If you are one of these users, you better keep reading as this post will guide you on how you can fix this error. To resolve this issue, there are several workarounds you can try. You can either disable this option directly via properties or you can also modify some registry entries or sub-keys and restart the system. When you encounter this problem, an error message pops up that states:

“The remote computer that you are trying to connect to requires network level authentication (NLA), but your windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using the options on the Remote tab of the System Properties dialog box.”

Or you could also see this error message instead:

“The remote computer requires Network Level Authentication, which your computer does not support. For assistance, contact your system administrator or technical support.”

Before you proceed in troubleshooting the problem using the options provided below, you need to create a backup for your data or system restore point as well as make a copy of any registry entries you are going to modify.

Option 1 – Disable Network Level Authentication via Properties

The NLA is a useful tool that provides your computer with extra security and helps network administrators in controlling who can log into the system with just a click of a single box. However, there are times when it can become a disadvantage and could prevent you from accessing your system remotely. Thus, you need to disable it using Properties.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” and tap Enter to open System Properties.
• Next, go to the remote tab and uncheck the checkbox for the “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)” option.
• Now click the Apply button to save the changes made and exit System Properties and then try logging into the remote computer again and see if the problem is fixed or not.

Option 2 – Disable NLA via Registry Editor

Note that you can only use this option if the first one didn’t work for you. Take note that this option will require you to restart your PC completely which could mean some downtime if your computer is running a production server. So make sure to save all your work.

• Tap the Win + R keys to open the Run dialog box and then type in “Regedit” in the field and tap Enter to open the Registry Editor.
• From there, click on File > Connect Network Registry and input the details of the remote computer and then try to connect.
• Navigate to the path below after you’re connected:

HKLM >SYSTEM > CurrentControlSet > Control >Terminal Server > WinStations > RDP-Tcp

• After that, change the values given below to “0”
  • SecurityLayer
  • UserAuthentication
• The navigate to PowerShell and execute this command – restart-computer

Option 3 – Disable NLA via PowerShell

PowerShell allows you to tap into the remote computer and once you’ve targeted the machine, you can execute the commands given below to disable NLA.

• Tap the Win + S to open Search and then type in “PowerShell” in the field. Right-click on the related result and select the “Run as administrator” option.
• After opening PowerShell, execute the command below:

$TargetMachine = “Target-Machine-Name” (Get-WmiObject -class “Win32_TSGeneralSetting” -Namespace rootcimv2terminalservices -ComputerName $TargetMachine -Filter “TerminalName=’RDP-tcp'”).SetUserAuthenticationRequired(0) Note: In the command given, the “Target-Machine-Name” is the name of the machine you are targeting.

Option 4 – Use the Group Policy Editor to disable NLA

Another option you can use to disable NLA is via the Group Policy Editor. This is ideal for you if you are blanket disabling. Just take note that the Group Policy Editor is a powerful tool and that if you make some mistakes by changing values you have no clue about, you can render your computer useless so make sure that you create a backup for all the values before you proceed.

• Tap the Win + R keys to open the Run dialog box.
• Then type in “gpedit.msc” and tap Enter to open the Group Policy Editor.
• From there, go to this path – Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security
• After that, search for “Require user authentication for remote connections by using Network Level Authentication” and set it to disabled.
• Now check if the error is fixed or not.

When you get an igfxem.exe error in Windows, it is not really clear what does this means, usually, Windows throw us some code or we get a DLL error, rarely we get an EXE error. So what does this error means? Intel Graphics Executable Main Module, shortly called as IgfxEM module is a part of the Windows operating system. When you run Microsoft .NET Framework applications that use the AS/400 Data Queue ActiveX control (Mseigdq.dll) to read from and to write to IBM iSeries (AS/400) data queues, you may experience this error.

If you suddenly get a message telling you that “Your Windows license will expire soon, You need to activate Windows in Settings” on your Windows 10 computer but you know that your Windows 10 is already activated. Worry not for this post will help you get rid of that error message right away. Before you get started, make sure that you have the Windows product key with you. If you don’t, you can get it by running the following command in an elevated Command Prompt:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Take note of the product key and then proceed to the options given below.

Option 1 – Try activating Windows 10 again or use another product key

• If you’re sure that you have the correct product key, click the Go to the Settings button.
• After that, click the Activate button once again.
• If you have another license key, you can also use that as well, just simply click on the Change product key.

• After you enter the second command, you should see a Windows Script Host window with all the Windows licensing and activation status. Take note of the Activation ID.
• Next, in the same elevated Command Prompt, type this command – slmgr /upk <Activation ID>

Note: In the third given command, “/upk” stands for “uninstall product key”. This parameter uninstalls the product key of the current Windows edition.

• Restart your PC. After that, your computer will be in an unlicensed state so you need to re-enter the product key again.

Option 4 – Try rebuilding the Tokens.dat file.

The issue might be caused by a corrupted Tokens.dat file. The Tokens.dat file is a digitally signed file that stores most of the Windows Activation files so if it is corrupted then no wonder you’re having activation issues. To rebuild the Tokens.dat file, refer to these steps:

• From the WinX Menu, open an elevated Command Prompt.
• After opening Command Prompt, you need to type each one of the following commands and after you type each command, hit Enter.
  • net stop sppsvc
  • cd %windir%ServiceProfilesLocalServiceAppDataLocalMicrosoftWSLicense
  • ren tokens.dat tokens.bar
  • net start sppsvc
  • exe %windir%system32slmgr.vbs /rilc
• Now restart your computer.

Option 5 – Try running the Windows 10 Activation Troubleshooter

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 6 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.
