All Windows computers don’t fall in the same category because they have different SoC and internal components. Users can custom-build a gaming machine using internal parts manufactured by various brands. I have listed a few reasons why 0xc00007b persists in your computer. Read them all and identify the root cause early on to resolve the issue sooner.

Windows 10 to 11 Upgrade:

My computer ran into many Windows errors after upgrading the software from the 10th edition to the latest version. The software upgrade has lacked in many ways, even though Microsoft improved the UI/UX design as an update. The software upgrade may have disrupted the software components. My computer faced a similar problem, and I have mentioned the solution below.

Windows 11 Bugs and Glitches:

I’m an early Windows 11 adopter, and I have tested the software on Intel laptops, AMD laptops, and AMD desktops. In my testing, I used an unsupported Ryzen 5 1600 processor. Microsoft released a statement that the 11th edition has bugs and glitches. Over time, the Redmond-based company plans to improve the software.

Microsoft Visual C++ Redistributable Errors:

MS Visual C++ Redistributable packages have revived the gaming sector in the world. Game developers have built the games on Visual C++ Redistributable packages. One of the packages has gotten corrupted, causing the issue. We have to identify the corrupted package from the program list and inspect them.

Problematic Problems:

Third-party software developers don’t have the resources to release compatibility updates. You got multi-billion companies releasing compatibility updates early because they have the resources and Microsoft assistance. Many smaller companies have challenges releasing updates due to a lack of funding. Some programs clash with the operating system, and they cause problems. We have to take up the challenge and identify the problematic program.

Pirated Programs:

I know people who have installed pirated programs on Windows PC.

Ask yourself a question on why would an (unknown) developer spend hours patching a premium software.

These developers have accumulated experience by spending years mastering coding and programming languages.

These pirated programs have unknown threats, and they destroy your machine within.

Pirated Windows:

Unfortunately, I have witnessed many young users activate Windows copy. I’ve met a player online who suggests others activate Windows using the illegal program. Pirated OS comes with risks and you might be the victim of it.

PC Threats:

Malware single handled destroyed my Windows laptop in the past. No one can argue that many flash drives, removable drives, and devices stopped working due to malware obstruction. Data loss is another problem when the desktop or laptop has malware infected in the hard disk drives.

FIX: The application was unable to start correctly (0xc00007b) in Windows 11

I suggest the readers back up the photos, videos, documents, and files. We don’t know what’s lingering in your system, like viruses, malware, etc. I don’t want you to lose stored data on your Windows PC. Pick up a flash drive and copy the files to the removable drive.

Shut Down Windows PC

Shut down your Windows PC for a couple of minutes. The operating system dumps temporary files, background processes, startup programs, etc. Let me show you how to shut down Windows 11. The software boots necessary files in the next session and may resolve the issue.

1. Press the Alt + F4 keys together.

2. Click the “OK” button.

3. Let the PC shut down.

Shut Down Windows 11 PC

Give a few minutes, and I would give a minimum of ten minutes of sleep time. Disconnect the charger and let the laptop sleep for ten minutes. A charging computer pumps up the heat further, and we don’t want it. Turn on the PC after a few minutes of sleep time.

Inspect Operating System Files

Windows operating system files get corrupted when you overlook the damages. We don’t care about the software’s health and abuse the system for months. Almost everyone doesn’t pay attention to the software’s health, and the system files suffer from corruption later. Microsoft bundled a tool in Windows to identify the corrupted files and fix them when possible.

1. Click on the Start key.

2. Search for Command Prompt. Run the CMD as administrator.

Inspect Operating System Files (2)

3. Enter (SFC /scannow) in the empty field.

6. Scan reports revealed some corrupted system files, but the Microsoft built-in tool fixed them.

Remove Windows Threats

Scan Full Windows OS

Inspect your Windows PC for viruses, malware, spyware, adware, and others. We don’t know what malware protracted in the system and how it’s damaging the system files. Many pirated games or programs require DLL files, and the malware slowly tampered with the DLL file. Run a full system scan and drag the threats out of hiding.

You can use any antivirus system since we don’t want to influence your choice. Remember, antivirus protection should have good protection against the latest threats.

A complete system scan takes a minimum of sixty minutes to finish on the latest SoC. I implore the readers to take out sixty minutes or more for the system scan.

Quarantine the virus or malware from Windows PC without hesitation. Reinstall the operating system when you detect the same virus back in the machine.Use the official Windows ISO file for software reinstallation.

Remove Pirated OS

Removed Pirated Windows 11

My desktop doesn’t have an activated Windows copy. And I have two laptops with genuine copies of Windows out of the box. Microsoft offers a free version for the masses, and I never felt like activating the software. Free Windows 11 users prompt the activation watermark and lock personalization functions.
The world moved on the notch display, but Apple continues to supply newer iPhones with a notch.

Apple users have learned to ignore the notch.

Honestly, your brain will learn to ignore watermarks somewhere down the line.

Remove the pirated software and install Windows from the Microsoft-supplied ISO file. My desktop has Windows 11 installed from MS supplied USB maker.

Update Windows 11

Windows Update

Microsoft’s in-house team is putting hours into releasing Windows 11 updates for stability and improvement. However, I want you to follow a few rules before updating the software.

A. Read online news about the latest Windows update.

B. Watch some video reviews related to the Windows update.

MS can make a mistake and worsen the problem after the software update. Never install the major update on day one and wait for the world to try it first.
