When you reach the bottom of your screen with the mouse it will pop up and be visible again, just like in all Windows so far.

Error Code 48 – What is it?

Error Code 48 is a device driver error code that users can encounter on any Windows 2000 operating system and later versions.

It occurs when the connected peripheral device cannot be run as the Windows operating system’s driver required to install the programs for peripheral devices has either been corrupted or is incompatible with the system.

It prompts the user with the following message on the screen:

The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

Solution

Error Causes

Like most other Windows error codes, error code 48 is triggered by the following factors.

• Corrupted system registry files
• Presence of viruses in the device

There are times when the WMI Repository gets corrupted which results in the Provider Load Failure. To resolve this issue, you need to repair or rebuild the WMI Repository in your Windows 10 computer. In this post, you will be guided on how exactly you can do that. In case you don’t know, the WMI which stands for Windows Management Instrumentation is a set of specifications from Microsoft to consolidate the management of devices and applications in a network. The WMI is a database that stores meta-information and definitions for WMI classes. Using only these, the conditions of the systems can be known. You can find the WMI Repository in %windir%System32WbemRepository. It provides end-users with the status of the local or remote computer system. Keep in mind that you must not use this on the Server 2012 Cluster machine. Although there are command-line tools that can fix or restore the Windows Management Instrumentation repository. However, Microsoft suggests that it’s better if you verify if there is corruption. Here are a list of errors as well as permission issues you might encounter:

• Unable to connect to root default or rootcimv2 namespaces. It fails with the error code “0x80041002” pointing to “WBEM_E_NOT_FOUND.”
• 0x80041010 WBEM_E_INVALID_CLASS
• When you open Computer Management and Right Click on Computer Management (Local) and select Properties, you get the following error: “ WMI: Not Found” or it hangs trying to connect
• Trying to use wbemtest , and it hangs
• Schemas/Objects missing
• Strange connection/operation errors (0x8007054e)

To verify if there is corruption, you can try running the following command in an elevated Command Prompt:

winmgmt /verifyrepository

 After you enter the command, if there is a response saying, “repository is not consistent”, then the repository has an issue. If not, then something else is causing the problem. Since you are certain that corruption exists in the WMI repository, then here are some suggestions you need to check out to repair or rebuild the WMI repository.

Option 1 – Try to reset WMI Repository

• Type “command prompt” in the Start Search and right-click on Command Prompt from the search results and then select “Run as administrator”.
• After opening Command Prompt with admin privileges, type and enter this command: winmmgmt /salvagerepository

The command you entered is used when the winmmgmt command performs a consistency check. So if an inconsistency is detected, it will rebuild the repository.

• Next, execute this command to see if the WMI repository now comes back as consistent: winmgmt /verifyrepository

This command will perform a consistency check on the WMI repository.

• If it states that the WMI repository is not consistent, then you need to type and enter this command: winmgmt /resetrepository

This command is used to reset the repository to its initial state when the operating system was first installed.

Option 2 – Try to force recover the WMI Repository

The WMI Repository comes with a built-in self-recovery process so when the WMI service restarts or detects any corruption, it will automatically trigger the self-recovery procedure. This can happen in two ways:

• AutoRestore: This will use the backup images if the Volume Shadow copy or VSS backup is turned on.
• AutoRecovery: The rebuilding process will generate fresh images of the WMI repository based on the registered MOFs. The MOFs are available in the registry located at HKLMSoftwareMicrosoftWBEMCIMOM: Autorecover MOFs

Note: Autorecover MOFs is a key so double click on it to check its value. On the other hand, if the self-recovery procedure does not work, you can try to use the force-recovery process instead. How? Refer to these steps:

• First, you need to check the reg key value is empty or not under this registry path: HKLMSoftwareMicrosoftWBEMCIMOMAutorecover MOFs
• If the reg key value is empty, you have to copy-paste the reg key value from another computer. Just make sure that it’s from the System which is equivalent to the computer in question.
• Next, type and enter this command: Winmgmt /resetrepository
• After you enter the command, if you get an error that says, “WMI repository reset failed. Error code:0x8007041B. Facility: Win32”, then you have to stop all the Dependency Services on the WMI service by running the following commands:
  • net stop winmgmt /y
  • Winmgmt /resetrepository

This should fix the problem.

• Once you’ve opened CMD, type in this command to open the DISPART utility – diskpart
• After that, you should see a new black and white window that would say, “DISKPART>”.
• Next, type in “list disk” in the command line and tap Enter to see the list of all the Storage devices as well as your hard disk connected to your PC. Here, you have to identify your disk’s number.
• Type in this command where “X” is the disk number you have identified and then tap Enter – disk X
• Type in this command and hit Enter to clear the table records and all the visible data on the drive – clean
• Now you have to recreate a new primary partition of the drive so you’ll have to type in this command and tap Enter right after – create part pri
• A new primary partition has been created so you have to select it by typing this command and tapping Enter – select part 1
• Now you have to format it to make it visible to normal users by typing – format fs=ntfs quick

Note: If your platform supports the Unified Extensible Firmware Interface or UEFI, replace the “NTFS” with “FAT32” in the command on Step 10.

• After that, type in this command and tap Enter after – active
• Finally, type this command and hit Enter to exit the utility – exit
• After you prepare the image for the operating system, save it to the root of your USB Storage device.

Option 3 – Try to recreate all the partitions

If none of the first two options given above worked, then you can try to recreate all the partitions instead. All you have to do is restart the Windows installation process and wait until you get to the part that says, “Where do you want to install Windows?”. From there, you will see options like delete, format, extend, create new partitions, and many more. Now you have to select the Delete all the partitions options and then use the “New” button to create new partitions. Just make sure that you have one primary partition at least where you can install Windows 10. After that, continue the installation of Windows on the new partition. Keep in mind that when you create a new partition, it also recreates the partition table configuration which means that the chances of getting an error are very unlikely.
