How to Fix DLL Errors in Windows?

A general rule of thumb, which is followed by most users, is to download the specific missing DLL file and place it within the software’s installation directory. However, this can be harmful to your system as hackers often upload popular malicious DLL files to target systems. Thus, you should avoid downloading DLLs from the internet. And follow these steps to fix the DLL error:

Restart your computer
System restore to an earlier state
Run a malware/virus scan
Update all the hardware drivers
Running SFC /scannow command in command prompt
Then do as the error suggests, reinstall the program if it’s feasible. Game files can take several hours to install and therefore, reinstallation can be a cumbersome job. Also, frustrating if the error appears after reinstallation.
Update device drivers manually, such as graphics drivers, DirectX software if you see DLL missing error while running game

Fix Windows Cannot Find a System Image

If you have encountered the “Windows Cannot Find a System Image on This Computer” error while you are trying to restore a system image, then read on as this post will guide you in resolving this problem. A system image is basically a backup of your whole data in the system. For instance, it can be the backup data of your hard disk or the whole hard disk itself, or one of the volumes. This is really useful in some cases like when you are not able to get back into your system for some reason or when your system has been corrupted. In such cases, you can utilize this feature and get going safe and sound. However, not all things go the way as expected like when you make a system image of a drive for instance, or use that backup to restore data and you suddenly encounter the “Windows Cannot Find a System Image on This Computer” error. This kind of error occurs due to a number of reasons but worry not for your data is safe and you can fix this error easily. This error is most likely triggered by changing the name of the “WindowsImageBackup” folder. Renaming this folder will certainly be an issue since it is the one that stores all your data. Aside from renaming the WindowsImageBackup folder, renaming the sub-folders can also cause this error which means that renaming the sub-folders of the WindowsImageBackup folder can trigger the error. To fix this error, here are some suggestions that might help:

Option 1 – Try putting the WindowsImageBackup folder in the Root directory

Windows will have issues finding the WindowsImageBackup folder if it isn’t in the root directory of the drive so if it is not there, the “Windows Cannot Find a System Image on This Computer” error will pop up. When a folder is in a root directory, it means that it shouldn’t be stored within a folder but in the main directory instead. Thus, you need to put the WindowsImageBackup folder in the root directory to fix the error.

Option 2 – Don’t add any sub-folders in the WindowsImageBackup folder

Another cause of the error is when you add sub-folders in the WindowsImage Backup folder. Adding any sub-folders in this folder will only trigger the error so you should leave the folder as it is and you must not make any modifications to it. So if you have added sub-folders in it, make sure to remove them right away.

Option 3 – Make sure that there is one system image per USB drive

The error can also appear if you’ve stored multiple images inside a single USB drive as it could confuse Windows and will trigger the “Windows Cannot Find a System Image on This Computer” error. Note that storing system images of different volumes of your hard disk in a single USB will prevent you from restoring your data.

Option 4 – Try renaming the System Image folder

If you’ve just changed the name of the System Image folder after you store it on a USB stick or other external device, then it’s no wonder why you’re getting the “Windows Cannot Find a System Image on This Computer” error. Windows search for the default name, “WindowsImage Backup” folder when restoring your data so if it is not able to find it, it throws up this error instead. To fix the error, you need to change the folder back to its default name which is “WindowsImageBackup”.

Option 5 – Check the WindowsImageBackup sub-folders

As mentioned earlier, renaming sub-folders in the WindowsImageBackup folder can trigger the error so if you have renamed sub-folders in this folder, you need to change them back to their default names so that you can restore your data peacefully.

Blu-ray player does not recognize the disc

So, you just made some popcorns, dimmed light, relaxed in from of the TV, pressed play on your application and Blu-ray drive can not read your movie. Your movie night failed sadly, but there is hope and in this article, we are going to explore and offer you solutions on what to do when something like this happens so you do not miss another movie night and some hard-earned relaxation. Please note that in this article we are assuming that you are using a Blu-ray player on your PC, so some of the solutions presented are meant only for this case. So the first thing that you are supposed to do is to check the disc itself. You can turn the disc around and visually check the disc for fingerprints and scratches which can be fatal for disc playing, alternatively, you can try to play the same disc on another device and if it fails there also it is not the disc, it is your drive. So if it is no issue with the disc let's see that seems to be a problem with the drive. The common thing that could stop disc reading are cables, check all connections and cables in the back of your device to be sure that everything is plugged in correctly and nicely. After checking cables if the issue persists lens cleaning is the next step. Over time lens from the Blu-ray, the device becomes dirty and dust accumulates on it, there are special cleaning discs on market made especially for this purpose, to clean the dirty lens of optical devices. If you have one put it in and clean your lens. After lens cleaning with a specialty disc, a good idea would be to use compressed air in a can to reduce the dust inside so no excess dust will accumulate quickly again on the lens itself.

So the device is cleaned and checked and still no disc playing?

Update firmware first. In order to accomplish this visit your device manufacturer's website and follow instructions there on how to upgrade firmware. If this did not helped also update or reinstall device drivers. Go to device manager and update drivers for your device by right-clicking on it and choosing update driver. If none of the things helped, go to command prompt as administrator and type in SFC /scannow, leave the process to finish, and reboot.

Fix Could not find the Recovery Environment

If you suddenly find the Windows Recovery Environment not working and you see an error message saying, “Could not find the recovery environment”, then you’ve come to the right place as this post will guide you on how you can fix it. In times when you can’t boot into the Windows Recovery Environment, there could be several reasons behind it. However, have you ever wondered where exactly the Windows Recovery Environment is in your computer? Windows initially places the Windows RE Image file in the installation partition during Windows Setup so if you have installed Windows in the C drive, you can find the Windows RE at the C:/Windows/System32/Recovery or C:/Recovery folder. Keep in mind that this folder is hidden and later on, the system copies the image file into the recovery tools partition to make sure that one can boot into recovery if there are any issues with the drive partition. The “Could not find the recovery environment” error mostly occurs if the Windows Recovery Environment is disabled or if the “Winre.wim” file is corrupted. Thus, to fix this error, you need to refer to the given suggestions below.

Option 1 – Try to enable Windows Recovery Environment

In the Windows Start Search, type “PowerShell” and from the search results that appear, right-click on Windows PowerShell and then select the “Run as administrator” option to open it with admin privileges.
Next, type the “reagentc /info” command and tap Enter to execute it.
After that, if the output states that Status is enabled, then you’re all set.
Now type the “reagentc /enable” command and tap Enter to enable the Windows Recovery Environment. You will see a success message at the end signifying that Windows RE is available.

Option 2 – Try to fix the corrupted or missing “Winre.wim” file

If the Winre.wim file is either corrupted or missing, you need to get a new copy of this file from another computer where the Windows RE is working. Once you’re able to get a new copy of the Winre.wim file, you have to set the image path to a new location. For more details, refer to these steps:

First, type “Powershell” in Windows Start Search and right-click on Windows PowerShell from the results, and select Run as administrator.
Next, execute the given command below to change the path of the WIM file to the new location. Note that the steps should be used when the file path of the Windows Recovery Environment is different from the usual spot.

Reagentc /setreimage /path C:RecoveryWindowsRE

As mentioned, if the file is corrupted, you just have to get a new copy from another PC but before you do that, make sure that the WINRE on that computer is disabled (just enable it later on) and then place it in the C:/Recovery path and then set its path again using the command given above and then verify its path by executing the following command.

reagentc /info command

Note: Since the Recovery folder is hidden as well as the WINRE folder in it and you won’t be able to access them using the Windows File Explorer, you need to use the Windows PowerShell or Command Prompt so that you can access them.

Option 3 – Try checking and fixing the WinRE Reference in the Windows Boot Loader

The Windows Boot Loader is the one that determines if it has to load the Windows Recovery Environment. It could be that the boot loader is pointing to an incorrect location which is why you’re getting the error. To resolve it, you have to check and fix the WinRE Reference in the boot loader. How? Follow these steps:

In the Windows Start Search, type “PowerShell” and from the search results that appear, right-click on Windows PowerShell and then select the “Run as administrator” option to open it with admin privileges.
After that, execute the “bcdedit /enum all” command.
Next, look for an entry in the Windows Boot Loader identifier set as Current and look for “recoverysequence” in that section and take note of the GUID.
Ensure that the device and the osdevice items show the path for the Winre.wim file and that they are the same. If not, you need to point the current identifier to the one which has the same.
Once you’ve found the new GUID, execute this command: bcdedit /set {current} recoverysequence {GUID_which_has_same_path_of_device_and_device}
Now check if the error in the Recovery Environment is fixed or not.

Option 4 – Try creating a Recovery Media

You could also try creating a Recovery Media to resolve the error in the Windows RE. All you have to do is download the Windows 10 ISO file using the Media Creation tool and then create a recovery drive. Once you’re done, check if it fixes the problem or not.

Hive ransomware on Exchange servers

Hive ransomware has been targeting Microsoft exchange servers lately vulnerable to ProxyShell security issues in order to deploy various backdoors. Once the backdoor has been placed various attacks can be performed including but not limited to network reconnaissance, stealing admin accounts, taking valuable data, and even installing and deploying file-encrypting algorithms.

ProxyShell wide abuse

ProxyShell is a set of three vulnerabilities in the Microsoft Exchange Server that allows remote code execution without authentication on vulnerable deployments. The flaw has been used in past by various ransomware like Conti, BlackByte, Babuk, Cuba, and LockFile.

Security vulnerabilities have been reported to be fully patched on May 2021 but how Hive was able to still be successful in exploiting PowerShell and infiltrating into the system there seems to be still some unpatched and open issues.

Hive

Hive has gone a long way since it was first observed in the wild back in June 2021, having a successful start that prompted the FBI to release a dedicated report on its tactics and indicators of compromise.

In October 2021, the Hive gang added Linux and FreeBSD variants, and in December it became one of the most active ransomware operations in attack frequency.

Last month, researchers at Sentinel Labs reported on a new payload-hiding obfuscation method employed by Hive, which indicates active development.
