How to Fix Unknown Hard Error in Windows 10

What is DownloadAdmin/ Updateadmin?

As a digital creation of Blueis, the DownloadAdmin application peruses your computer system for programs/applications that are outdated. This program then makes the necessary updates/installation on your computer, as if it were the Administrator. While most people might consider this application harmful, scrutinizing the Digital Publisher/Creator of the application should be reason enough to remove DownloadAdmin (and any other associated program) from your computer. Why? Blueis is infamous for producing/distributing “adware type software”, according to herdProtect Anti-Malware. Is that not a plausible reason for you to remove applications associated with that publisher? Additionally, DownloadAdmin not only updates your outdated applications, but it installs additional programs - usually utility tools and search toolbars. This is a sly way to promote third-party software and to get ads loaded onto your computer system. Technical details about DownloadAdmin include:

Digital Publisher: Blueis Product Version: 4.0.0.1 Original File Name: DownloadAdmin Entry Point:  0x0000234A

Assessment of DownloadAdmin

For this assessment, the DownloadAdmin file was obtained and installed on a test computer. After the DownloadAdmin/Updateadmin application was installed, it made several modifications to the computer system. These modifications may class the newly installed file as a PUP (potentially unwanted program). Outlined below is what took place after the file was installed.

• Updated an outdated application installed on the computer

Subsequent to the update made by Updateadmin, I thought the PUP had run its course. However, it was not quite finished. It was after scanning the contents/programs of my Local Drive, I stumbled on an additional program, one that I did not download or install, at least not intentionally. As predicted, the DownloadAdmin application scanned through the computer system (in the blink of an eye), during installation and made adjustments to an application already installed. This program was the Mozilla Firefox. Since Mozilla Firefox was rarely used on the PC in question, the DownloadAdmin application thought it quite appropriate to revive the Mozilla Firefox browser, by replacing it with the latest or more contemporary version.

• Installed a search toolbar

While DownloadAdmin did request permission to install an updated version of my Browser, it provided no warning about installing a search toolbar. This is quite shady and deceptive. In addition to updating the Internet Browser, DownloadAmin also installed the SearchProtect toolbar (Conduit). This toolbar is no stranger to the market as I’ve encountered it on several occasions during my assessment of malware.

Should you remove DownloadAmin?

That decision is totally yours to make. However, here are some reasons why most people would consider that program unwanted

• It updates your outdated programs

In most cases, at least those I’ve seen, if a user has a program installed, they don’t necessarily want a new version of that program. In fact, this PUP could spell trouble since some programs, especially paid, require a license to use the software. When that program is updated/ upgraded, you might have to acquire a new license to get it to work.

• Unnecessary program

If you’re totally lackadaisical and loathe the idea of doing work yourself, this program might come in handy. Many users will update their computers manually by using Microsoft’s preinstalled/pre-programmed updater in their computer’s Control Panel. This option searches for and installs all the necessary programs to keep your computer safe and secure. The DownloadAdmin program only occupies needed space and resources on your computer. However, what’s good about this program is that it doesn’t operate at the start time so it doesn’t necessarily cause unnecessary lags on your computer.

• Modifies your search experience

By installing a search toolbar called SearchProtect, Updateadmin modifies or changes the browsing experience you’re accustomed to. SearchProtect hijacks your browser and changes your homepage to their choice while removing yours. This is often hard to reverse since the publisher created this software to remain once installed.

What is Error Code 37?

Error Code 37 is a Device Manager Error Code that you may come across when you are unable to use an installed hardware device on your PC. It will pop up on your screen with the following display:

“Windows cannot initialize the device driver for this hardware. (Code 37)”

If you receive the above message, it means that your operating system was unable to acknowledge the drivers for a particular peripheral device.

Solution

Error Causes

Error Code 37 mainly occurs due to device driver corruption. However, there are other factors that can trigger this error code, some of which are the following:

• Missing device drivers
• Out-of-date device drivers
• Presence of malware or spyware in the system
• The particular device is not compatible with your PC

Device driver corruption or other data corruption is not uncommon and part of everyday PC use.

From an installation gone wrong to an unexpected shutdown, commonly generated data errors are considered the main culprit behind error codes.

Further Information and Manual Repair

Just like most PC error codes, Error Code 37 isn’t that difficult to get rid of. There are many DIY methods you can try to have your PC running smoothly in no time. Here are a few methods to resolve this issue:

Method 1: Restart your PC

It is possible that the display of the error code is merely due to a temporary issue with your peripheral device and not anything serious.

Therefore, the quickest and easiest method to solve the error code 37 is to simply restart your PC.

Method 2: Scan for Viruses

If restarting does not do the trick, a quick scan for viruses and removing them is another simple method you can follow to fix your PC.

Since the error code is due to corruption of data, viruses such as malware or spyware create error in your PC’s registry and eliminating them can help restore some of the corrupt data, which also speeds up your PC.

Method 3: Undo recent changes

A possible explanation for the error code may be the recent changes in your Device Manager or due to the peripheral device installation. You can thus undo the changes by either:

• Remove or change settings of the installed peripheral device
• Roll back the version of the driver to the one before the update.
• Use System Restore to reverse the changes made in the Device Manager

Method 4: Manually uninstall and reinstall the drivers

If the above stated methods do not help in speeding up your PC and is still giving you an error code, you may want to manually uninstall and reinstall the corrupt or missing drivers. Here are the following steps:

• Double-check if the installed external device is properly connected and working smoothly
• Open Device Manager and double click on the device that is causing problems
• When it opens, click on the ‘Driver’ tab and click ‘Update Driver’

Method 5: Use DriverFIX

However, updating the missing or corrupt drivers can be time consuming and may also require having a hardware documentation ready that contains specific details about the driver that you should download.

To avoid this time-consuming process, you can use DriverFIX software.

DriverFIX will help you to download the required driver without you having to waste your precious time and effort looking it up in a user manual.

Updating your Windows 10 computer does not always go smoothly as there are some errors you can encounter along the way. One of these Windows Update errors is the error code of 0x80246008. This kind of error can occur during different phases of an update that’s being downloaded or installed and even when an update is being initialized. If you narrow down the cause of this Windows Update error, you’ll most likely see that it is related to the deliverability of a file to a computer from the servers of Microsoft. In other words, the error might be due to conflicts from programs like Firewall as well as third party programs like Antivirus or it could also be due to corrupted disk image or system files or it could be that any of the supporting Windows Update components and services are not working properly. Whatever the cause may be, the potential fixes provided in this post can be applicable to Windows Updates as well as the Microsoft Store. Refer to the suggestions provided below to resolve the Windows Update Error 0x80246008 but before you proceed, make sure that you create a System Restore point first.

Option 1 – Apply some tweak in the Windows Registry from Command Prompt

• Tap the Win + X keys and select Command Prompt (Admin) to open Command Prompt with admin privileges.
• Next, navigate to the root location of the bootable device inside the Command Prompt command line.
• Once you’re in the root location, type the following command and tap Enter to execute it:

reg add HKLMSYSTEMCurrentControlSetControlBackupRestoreFilesNotToBackup

• After that, close the Command Prompt command line and then tap the Win + R keys to open Run utility.
• In the field, type “services.msc” and click OK or tap Enter to open the Windows Services Manager.
• From there, look for the following services:
  • Windows Update – Manual (Triggered)
  • Background Intelligent Transfer Service – Manual
• Now open their Properties and make sure that their Startup type is as mentioned above and that they are running. If they are not running, just click on the Start button.

Option 2 – Run the System File Checker Scan

If the registry tweak didn’t work, you can run a System File Checker scan instead. It is a built-in command-line utility that replaces bad and corrupted system files to good system files that might be the cause why you’re getting the error when you try updating your computer. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer.

Option 3 – Run the Windows Update Troubleshooter

If the System File Checker wasn’t able to resolve the Windows Update error, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including this one. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Try to disable your antivirus program

Disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 5 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer.

If you experience this error, check first if any of your newly installed hardware is compatible with Windows 10. You can find the required hardware for Windows 10 from this link. 

If all your hardware is compatible with Windows 10, you might need to check the device driver or system service. Review the bug check message. If any of the drivers you have is listed in the message, either disable or uninstall them before upgrading or setting up Windows 10.

You might also find it useful to check the System Log available in the Event Viewer for other error messages that can help you figure out the driver or device that’s causing the error. Running hardware diagnostics can also be useful.

Method 2 – Disable (or preferably uninstall) Software Before Upgrading

If you’re upgrading Windows 10 from Windows 7 or Windows 8.1, you might need to disable or uninstall the software first. First, try uninstalling your Antivirus utility before starting the upgrade. Restart a few times before starting the Windows 10 installation. If you’re upgrading using the Windows 10 update, make sure that you disconnect from your Wi-Fi or Internet LAN (Ethernet) connection as soon as the download reaches 100% before attempting to start the set-up. Other users also reported that the cause of the KMODE_EXCEPTION_NOT_HANDLED issue is BitDefender. If this is what happened in your case, it will show in the error message such as KMODE_EXCEPTION_NOT_HANDLED (bdselfpr.sys). Users reported that a common solution for this is renaming the file. In the case of BitDefender, try renaming it to bdselfpr.s__. However, make sure to do this cautiously. Sometimes, renaming a file will even do more damage than good.

Method 3 – Disable/Disconnect From Hardware

If you’re connected to any general USB devices (such a smart card reader), disable it. If your computer is connected to other external devices, disconnect all of them. Examples of this include gaming controllers, printers, external hard disk, USB keys, and other non-essential devices).

Method 4 – Other Troubleshooting Steps

Other troubleshooting steps include:

• Upgrade using an .ISO file, instead of directly upgrading from Windows Update. When you do this, make sure you’re disconnected from the Internet during installation. If the process started and you forgot to disconnected, it’s best to restart the installation.
• If you’re connected to a domain while trying to set up Windows 10, disconnect and use a local account.
• If you’re using a SCSI hard disk, connect a thumb drive with the drivers for your storage device. While Windows 10 is setting up, click on the Custom Advanced Option. Using the thumb drive, use the Load Driver command to load the SCSI drive.
• Another possible cause of this error is due to BIOS incompatibility. BIOS issues can be solved by upgrading your version of your system BIOS. If you don’t know how to do this, refer to your BIOS manufacturer’s website.

Method 5 – Use A Trusted Automated Tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.
