Tips and tricks for longer SSD life

From the various report, it is now clear that no one is prone to Ransomware attacks. Cyber-criminals never target any specific field of the user workgroup for this Ransomware attack. But in past few years, it has hugely affected home users, businesses, organizations. We can say, Ransomware victims come in all shapes & sizes. Many business owners think that they will never be attacked by Ransomware crooks because their business is not so big. But that’s not true. A huge proportion of Ransomware attacks happened in small sector businesses because of their weak security resistances.

Some leading negative consequences of Ransomware attacks faced by almost every victim are:

1. Permanent or temporary loss of proprietary or sensitive information.
2. Lots of trouble in performing regular operations.
3. Huge financial losses sustain for restoring up your files and systems.
4. Latent harm to the reputation of an organization.
5. Even making the Ransom payment doesn’t guarantee the safe releasing of your encrypted files.
6. Attackers get the victim’s money along with their banking details.
7. Getting the decrypting files doesn’t mean malware infection has completely been removed.

Ransomware put a tremendous impact on disturbing business operations and in the end, leads to data loss situations.

Here are some huge impacts of Ransomware attacks on business are:

1. Damage or loss of all the crucial information
2. In the Ransomware post-attack period Business disrupts a lot.
3. Destruction of hostage data, file, and system.
4. Business downtime
5. Victimized company’s reputation dropdown
6. Productivity loss

Apart from the ransom, the cost of downtime because of restricted system access will bring major concerns. It’s a fact that due to downtime victims may has to pay a cost of ten thousand dollars daily. As, Ransomware is becoming more and more widespread, so all companies require to brush up on their annual cyber-security goals. Moreover, approach for some appropriate implementations of Ransomware recovery plans and commit sufficient funds in their IT budgets for cyber-security resources. Among the most effective impact of Ransomware, “data encryption” is very hard to deal with. Meanwhile, this victim is completely restricted to access any of their encrypted data. The only way for unlocking these encrypted files is through the decryption key which only belongs to hackers. Many times, the decryption key is given to the organization, after the payment of the ransom. But there are also some cases when data is not handover to the victim, even after the ransom payment. The main risk that generates with “operational impact of Ransomware” is on the businesses. Can you just imagine, what will happen if all of a sudden entire services or processes of your business halt down?

Well, this dreadful Ransomware threat is so impactful that it can:

1. Close down the entire plant
2. Freeze manufacturing control system
3. Make other backlogs

All the damages that occur due to downtime can be a major one and can have so many consequences. A well-organized strategy of backup and recovery will not certainly make the Ransomware attack painless. As this takes an extensive amount of money and time for data restoration.

Apart from that, the decision of recovering your system using the backup moreover depends on three things:

1. First the amount of data loss that is considered acceptable by your business or organization.
2. Up to how extent, the impact of Ransomware has spread
3. How fast the Ransomware attack was spotted.

However, in many cases, data gets so encrypted that you can’t revert back to the restore point. At that time external backup is considered the best option. Among the wide-reaching impact of Ransomware “Data loss” is the most effective one.  As it starts from little disruption and leads to permanent business failure. Sometimes data loss in a Ransomware attack leads to disclosure of all your confidential information which ends up in fines and lawsuits. Attackers always look for backup files and folders after encrypting your system data. So that user can’t retrieve their corrupted file from the backup. Such dreadful activities make this Ransomware threat so profitable and effective. Victims don’t have any choice left either they have to pay the ransom or they have to face their risk of data loss.

There are instances when the Windows 10 installation needs interaction before it reaches the file process. And so if you suddenly encounter the Windows Update Installation Failure 0x80240020 error under the Windows Update History, then you need to get it fixed. When you encounter this kind of Windows Update Error, you will see an error message that says, “The operation did not complete because there is no logged-on interactive user”. This error also indicates the “WU_E_NO_INTERACTIVE_USER” code. To resolve this issue, in this post we’ll walk you through a couple of steps but before you get started, know that you don’t have to run any troubleshooter or delete any file just to fix this error since all you have to do is enable one option that can automatically login with your account and complete the installation for you. With that said, just make sure to only try running Windows Update once you’re told to do so. There are two ways you can enable the option that could resolve the Windows Update Installation Failure 0x80240020 error. One is via Settings while the second one is via Registry Editor.

Option 1 – via Settings

Step 1: Go to Settings > Accounts > Sign-in Options. Step 2: From there, toggle on the “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart” option. Step 3: After that, it will make sure that the interaction part is removed from the Windows Update process. Note: If your device is joined in a domain or if some work or email policies are applied to your device by your company or organization, then you wouldn’t be able to see this option in Settings and that’s where the Registry Editor comes in. Just make sure that you’re logged in as an administrator and that you create a System Restore Point first since registry hacks are sensitive and could highly impact how your computer behaves or functions. Once you have that covered, follow the steps below.

Option 2 – via Registry Editor

Step 1: In the Start search, type “Regedit” and hit Enter to open the Registry Editor. Step 2: Navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade

Note: If the above-given registry key does not exist, you can simply create it. All you have to do is right-click on the WindowsUpdate key and then select the New Key option and type “OSUpgrade” as its name. Afterward, create a new DWORD (32-bit) Value and name it “AllowOSUpgrade” and set its value to 0x00000001. Step 3: Restart your computer and check if the error is now fixed. And then try to update your Windows 10 computer again and while you’re at it, make sure that you’re around your computer to interact with the prompts needed to complete the installation process.

Windows has a lot of built-in tools that help you fix tons of system-related issues. One of them is the System File Check which is the tool you can use to conveniently replace potentially corrupted or missing system files with good ones. But what happens when it does not work? Well, you’ve come to the right place as in this post, you will be guided on how you can replace a corrupted single Windows system file manually with a known good copy of the file if the System File Checker scan is not working. When you encounter this issue with the System File Checker, it will be unable to replace the corrupted system files and returns an error message instead. And so to fix and replace corrupted system files in your Windows 10 computer without the help of System File Checker, you can refer to the instructions provided below. Step 1: First, you need to open the log files listed below and identify which particular file has been corrupted:

• %userprofile%Desktopsfcdetails.txt
• Log %WinDir%LogsCBSCBS.log

Step 2: You will see all the details on the given log files. Once you find out the name and the path of the file, you have to take ownership of this corrupted system file. Step 3: To take ownership of the corrupted file, you need to pull up Command Prompt by tapping Win + R keys on your keyboard and then type “cmd” and tap Enter. Step 4: After opening Command Prompt, type and enter the command below to execute it:

takeown /f FileNameAndPath

Note: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll” Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again. Step 6: In the elevated Command Prompt, type and enter the following command to execute it:

icacls FileNameAndPath /GRANT ADMINISTRATORS:F

Note: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”. Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:

copy NewFileLocation FileNameAndPath

Note: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”

Many of us are taking the google search engine for granted and it is no true that it has crawled in almost every spore of our digital lives but if we wanted a little more privacy? Do we have options or we are destined to use google and send our information to this company. What if we really wanted that our searches are well safe, secure, and private?

This will hopefully resolve error code 41 on your system and you will be able to use your desired hardware device without any hassle. Nonetheless, if the error code continues to persist, try other methods illustrated below.

Method 2 - Replace the Hardware or Try Reattaching it to your System

Sometimes the error may pop up due to poorly configured devices. This is common if it is a plug-and-play device. The best way to resolve is to remove the device, reattach it properly, and then try using it again.

However, if the problem is with the hardware, then it is advisable to replace the hardware with a new device compatible with your Windows version.

Method 3 - Update the Drivers Manually

If the underlying cause for error code 41 is outdated or corrupted drivers, then it is advisable to update the drivers.

However, when updating drivers and ensuring that the newly installed drivers work perfectly, make sure you install versions that are compatible with your device and Windows. Incompatible drivers are no good.

You will continue to face Device Manager Errors if you install incompatible drivers.

To update drivers, here’s what you have to do:

• Identify the problematic drivers
• Go to the Device Manager and locate all drivers with yellow exclamation marks
• Now install new and compatible driver versions from the manufacturers’ site

Method 4 - Download Driver Assist to Update Drivers Automatically

During Windows 10 installation, you will see all the beautiful user interfaces, however, what’s more, important are the drivers, your processor, and free storage disk in order for the installation to be successfully completed. So if you are getting the CompareExchange128 error during the installation of Windows 10, this means that the CPU lacks a very important instruction known as “CMPXCHG16B”. Thus, if you don’t have CMPXCHG16B, then it will result in the CompareExchange128 error when you install Windows 10. In fact, CMPXCHG16B, PrefetchW as well as LAHF/SAHF is a criterion for you to be able to use Windows 10 64-bit version when upgrading from an earlier version of Windows. So what exactly is the CMPXCHG16B instruction? The CMPXCHG16B instruction is the one that performs an atomic compare-and-exchange on 16-byte values. This instruction can also be referred to as “CompareExchange128”. The atomic compare-and-exchange means that the CPU compares the contents of a memory location with a given value. So if the values are the same, it modifies the contents of that memory location to a new given value. Note that this kind of issue only happens to the 64-bit Windows 10 version and the only way to resolve it is by getting an update on the hardware level from the OEM. On the other hand, if nothing really works, it’s maybe time for you to get a new CPU but before you resort to that, in the meantime, you can try following the options given below to fix the CompareExchange128 error during the installation of Windows 10.

Option 1 – Try to update the BIOS and Chipset Drivers

One of the best things you can do to fix the CompareExchange128 error is by updating the BIOS and chipset drivers which is why you need to check if your OEM has an update available for your computer’s BIOS as well as the related chipset drivers. But before that, you need to first check the BIOS version. To do so, follow these steps:

• Type “msinfo32” in the search bar and hit Enter to open the System Information Tools.
• After opening the System Information Tools, check the BIOS version.
• Then take note of that BIOS version. You also need to use the BIOS utility that came with your computer and use it for the upgrade. Note that it is different for every computer and if you don’t have it, you can just go to the OEM website and see if there is an option to download it there.

Option 2 – Try to downgrade to the 32-bit Windows 10 version

If option 1 didn’t work as the BIOS update is not available, you can also try downgrading to the 32-bit version of Windows 10. Keep in mind that this will bring restrictions on the amount of RAM installed and other places but that won’t be a problem as you can still switch.

Option 3 – Try buying a new hardware

If none of the first two options didn’t work for some reason then maybe it’s time for you to purchase new hardware especially if your computer is way too old. In such cases, it’s better to buy new hardware or better yet, a new computer that can keep up for the next couple of years.

Windows 11 is coming soon, from its typical view and color scheme, Windows 11 will natively support dark mode. The dark mode is very popular in many applications today, some large companies like Adobe, Autodesk, and many more have already adopted a dark color scheme for their software so it is logical for others to follow and Microsoft is aboard for it. The dark mode itself has its benefits, for people who work on computer for longer period of time dark mode inside applications will throw less white and blue light on their eyes making workhours easier and pleasant on them. As a person who does indeed spend a lot of time in front of the screen, I would advise you to switch to dark mode regardless of the time that you spend with a computer, your eyes will be grateful.

Switching to Dark mode in Windows 11

1. Open Windows 11 Settings by pressing ⊞ WINDOWS + I
2. Click on Personalization on the left sidebar
3. On the right side click on Color
4. In color options click on the drop-down menu right next to Choose your color
5. Select Dark

Your choice will be applied right away and you can safely close settings.

Stop C00002lA Fatal System Error- What is it?

C00002lA Fatal System Error is a blue screen of death error that may occur when you start your Windows NT 4.0 based computer. This error causes the screen to turn blue and the system also shuts down. The stop C000021A error message is displayed in the following format:

Stop c000021a {Fatal System Error} The session manager initialization system process terminated unexpectedly with a status of 0xc0000017 (0x00000000, 0x0000000) The system has been shut down.

Error Causes

The stop C000021A error occurs when either Crsrss.exe or Winlogon.exe fails. When the Windows NT kernel identifies that either of these processes has failed, it stops and the error code stop C000021A appears on the computer screen. Here are some of the underlying causes for the stop C0000021A error:

• The incompatible third-party program
• Hard disk issues
• Service pack installation has failed
• Mismatched system files have been installed
• Bad and invalid registry keys

Further Information and Manual Repair

To resolve the stop C000021A Fatal System Error on your PC try the following solutions:

• Remove Incompatible Third Party Programs

If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program. To remove the program go to the start menu and click on the control panel. Now click on Add/Remove Program tab and double click on the program name that you recently installed and remove it from the list. Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.

• Repair and Restore the Registry

This procedure is slightly long and tricky. To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT. Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive. Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST. Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1. This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002. Now locate the following registry key: HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open. Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys: HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation. This will resolve the stop C000021A error.

5. Remove entries in the HOSTS file

   If the previous solutions do not work, your computer could have trouble connecting to Adobe's activation servers. This could be because of an incorrectly configured Operating System hosts file (Operating system hosts files map host names to IP addresses). To solve this issue, try removing Adobe-related entries from the hosts file. You can remove the Adobe-related entries from the hosts file in two ways: Automatically repair the hosts file using the Limited Access Repair tool: Repair the hosts file using the Limited Access Repair tool. With this method, you do not have to manually edit the hosts file -- the tool automatically repairs the file. Reset the hosts file manually: If the issue is not fixed even after you run the Limited Access Repair tool, reset the hosts file manually: To reset the hosts file on Windows, do the following: Navigate to C:\WINDOWS\System32\drivers\etc. Open the hosts file with a text editor such as Notepad. Check for any Adobe-related entries in the hosts file. If there are Adobe-related entries in the hosts file, move the file to the desktop, for example by dragging. Delete the Adobe-related entries from the hosts file. Make sure that you do not delete any other entries. Save the hosts file that you edited in the previous step. The updated hosts file should not have any Adobe-related entries. Move the file from desktop to the original location: C:\WINDOWS\System32\drivers\etc. When moving the file, select the Replace option. To reset the hosts file on macOS, do the following: To find the hosts file, open Finder and then choose to Go > Go to Folder. In the box, type the following location and then press Return: /private/etc/hosts If you are unable to locate the file, it means that the hosts file is hidden. Type the following command in terminal to unhide the file, and then repeat Step 1. chflags nohidden /etc/hosts Open the hosts file using a text editor such as Text Edit. Check for any Adobe-related entries in the hosts file. If there are Adobe-related entries in the hosts file, move the file to the desktop, for example by dragging. Delete the Adobe-related entries from the hosts file. Make sure that you do not delete any other entries. Save the hosts file that you edited in the previous step. Move the file from the desktop to the original location: /private/etc/hosts. When moving the file, select the Replace option.
