Due to its hybrid core technology, the Alder Lake line of processors had some DRM issues with some game titles where DRM protection software detected hybrid core design switching via manager as a hack attempt and prevented the game from working properly. Over 50 titles were affected by this issue, now only 3 remain still affected but it is being worked on them so that can be also resolved. Intel says that the remedy to the issue for these games is the scroll lock fix which can be done so by enabling Legacy Game Compatibility mode from the BIOS of your motherboard. When running the said games, you can press scroll lock to park the E-cores on Intel's Alder Lake Desktop CPUs to get rid of DRM issues. Certain motherboard manufacturers such as MSI and Gigabyte have made this even easier through software tools with which you don't have to access the BIOS. All you need to do is select a button in the tool which works on both Windows 11 and Windows 10 operating systems and you will enable compatibility mode.

What is this particular error?

One common issue when trying to upgrade to Windows 10 from Windows 7 or 8 is incompatible software. Any installed software or app that isn’t compatible with Windows 10 will prevent you from continuing with the set-up. Normally, you’ll get an error message “What needs your attention” and it will ask you to uninstall a list of apps manually. Unfortunately, some users reported that they couldn’t find the app it asks to uninstall. In some cases, users said they’ve already uninstalled the app but it still won’t start the Windows 10 Setup.

Solution

Error Causes

This type of issue normally occurs because of the following:

• Incompatible software/apps
• Corrupted software/apps
• Incomplete uninstallation

Further Information and Manual Repair

Here are some steps you can take whenever you encounter this error.

Note: Before taking any steps, make sure that you’re highly equipped to do so. Some steps might affect the system and even do more damage to your computer. You might also want to consider using an automated tool instead.

Method 1 – Perform a clean boot, then retry upgrading

A clean boot is normally done to start Windows using the least set of drivers and startup programs available. By doing this, it eliminates possible software issues that happen when installing or uninstalling a program in Windows 10.

Before performing a clean boot, make sure to take note of the following:

• You need administrative privileges in order to perform this action.
• When doing this, your computer might lose temporarily functionality. However, it will return after start-up.
• It is highly advisable to not use the System Configuration to change advanced boot options.

Here are the steps to perform a clean boot.

• Step 1 – Go to Start and search for msconfig
• Step 2 – Go to System Configuration
• Step 3 – Under Services tab, click on the “Hide all Microsoft services” checkbox. Then, choose to Disable all
• Step 4 – Go to the System Configuration’s Startup tab. Then, click on “Open Task Manager”
• Step 5 – In the Task Manager dialog box, you will see a Startup tab. Choose items that you want to disable and then click the Disable button
• Step 6 – Close the Task Manager dialog box.
• Step 7 – Go back to the Startup tab of the System Configuration box. Click “Ok” then proceed with restarting.

Method 2 – Manually uninstall programs from the Program Files folders

Instead of using the “add or remove programs” feature in Windows, you might need to manually install the program directly from the C drive. To do this, follow the steps below:

• Step 1 – Go to the C drive, and look for the Program Files folders. For 32-bit users, you can find it at C:\Program Files. If you’re using the 64-bit version of Windows, go to C:\Program Files (x86) folder.
• Step 2 – Find the “uninstall” application file
• Step 3 – Right-click, and run the file as administrator. Wait for the uninstallation to finish. In some software, you need to restart your system before the uninstallation will take effect.

Note: In some cases, you may also need to search for files related to the program. You can use the search bar under Drive C to do this. Delete those files as well.

Method 3 – Create a new user account

Before upgrading to Windows 10, create a new user account. Make sure it has administrative privileges. From there, run the upgrade.

Method 4 – Use third-party uninstaller services

If you still can’t run Windows 10 Setup after the above methods, you might need to rely on a third-party service. Microsoft recommends Revouninstaller that can help you.

Before using this software, reinstall the application or utility that Windows 10 wants you to install. Then, use Revouninstaller to delete the program completely.

Method 5 – Disable third-party antivirus software

Some users who experienced this issue reported that it was solved after disabling or completely uninstalling the anti-virus software installed in their system.

Method 6 – Use a trusted automated tool

If after trying the above methods, the problem still persists, it might be best to use a trusted automated tool to fix the issue.

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.
