Minecraft has taken the world by the storm, it was an indie project game and it went mainstream. Dream of every game developer I guess. The dream of every gamer on the other hand is to double click on the game and to play it and not to deal with various issues, especially if they are launch issues.
Luckily for all of you gamers, here at errortools we game as well and we are happy to bring you a solution on how to fix Minecraft won't launch issue. So sit back, relax and keep on reading, and hopefully enough you will be gaming again in no time.
Follow the guide presented step by step, point by point how it is presented for the quickest way to get back in Minecraft. This guide also presumes that your hardware configurations meet at least the minimum system requirements for running Minecraft.
90% of the time this is the issue why Minecraft is not working, your antivirus or firewall has detected it as a false positive, and access to system internet, etc has been cut. Try disabling it and if everything is working fine add it to the antivirus or the firewall exception list.
Minecraft will sometimes refuse to run if it does not has administrator privileges. To make sure this is the case locate the Minecraft executable, right-click on it and choose properties. Go to the compatibility tab and check Run as Administrator box.
It came to knowledge that even if Minecraft is not running it can have its processes active in the background.
Press CTRL + SHIFT + ESC to open task manager
Locate if Minecraft has a process running
If you find the Minecraft process right-click on it and choose End Task
If Minecraft still refuses to start try running it in compatibility mode in the previous Windows version
Locate Minecraft executable file in its install location
Right-click on it and choose properties
In the properties, windows go to the compatibility tab
Check run this program in compatibility mode for:
Select previous version of the operating system, try Windows 8 or Windows 7
The best bet is to go to your GPU manufacturer's website and download the latest version of the driver of your GPU.
Mods, plugins, texture packs are all great but sometimes they can cause GPU overloads and other issues to see if this is the case try running Minecraft in Vannila mode without anything installed, just pure and clean Minecraft as it was just downloaded and installed.
If everything else failed, reinstall Minecraft. There might be a chance that some DLL file was deleted or corrupted by mistake or that some crucial files are missing. Clean reinstallation will fix all of these issues.

According to Zimperium zLabs, this malware that was recently detected has been doing its scams and attacks even in November of 2020 and has thus far accumulated hundreds of thousands of dollars in its scam.
On the surface it looks very harmless, asking for typical permissions like internet access, calls, and other related needed functions, and then it waits. After few months the real attack happens when users get charged with premium service they never subscribed to in the first place.

Error CausesSo, you have finished with work, game, movie, music, email, or whatever on your PC, you look at the clock, it is late, you decide to go to sleep or outside, you click on the power button and choose shutdown. Now when a PC is shut down you feel good and go with your business but the next time you power it up you get the same error like the computer never really shut down in the first place. You wonder why and reboot it, just in case and all of the sudden error is gone.
If something similar has happened to you or you had the feeling that after shutting down your computer has not really felt like shutting it down, do not seek professional help, everything is OK with you because when you click on shut down, your computer does not really shut down!
Truth is that Microsoft has changed how to shut down works and how rebooting works in Windows with an update but has not publicly said anything about it so some users may experience this feeling of not shutdown phenomenon and might even think there is something wrong with their PC.
A few years ago shutdown button and option in Windows were really shutting down OS, but things changed when Microsoft wanted to increase boot-up speed. Now when that decision was made shutdown option was changed. So, what was changed? Well in order to increase Windows booting time, the shutdown will now turn off power to PC components and it will look like everything is indeed shutdown but the Windows kernel will actually be saved to a hard drive with all settings and just awaken once the PC is turned back ON. This will result in all errors and other stuff being just still present same as they were once the system was instructed to be turned off.
Rebooting your PC will now clear kernel and file from the hard drive and you will get a clean system startup without any issues tied with the kernel itself.
Now that we know why and what change has been made to Windows logical question is can we shut down our PC at all properly? Luckily for us, the answer is yes and we will not need any external application to do it, we can still do it inside Windows itself and it is quite quick and easy.
In order to bring the old shutdown functionality of your PC please follow the instructions but be aware that by doing this your PC will boot a little bit slower since it will have to load the kernel from scratch each time computer is turned ON.
First thing is to go to settings and go to System

Then once you are inside the system, navigate to the power and sleep and click on it to select it. Once you have it selected to all the way to the right and click on additional power settings.

When you click on advanced power settings you should be led to the control panel's power options. Inside this panel click on top left link where it says Choose what the power button does.

Inside options, you will need to untick the box next to Turn on fast startup (recommended), this option has been ticked ON by the Windows update and probably without notifying you. Option means exactly what was described, it will save kernel state on the hard drive for faster boot time but sadly it can cause some issues since it will never be reloaded from 0.
If you are unable to uncheck the box click on the text beside the shield icon that says: Change settings that are currently unavailable (you will have to be logged in as administrator).

Altho turning off fast startup and shutting down the PC completely will for sure extend your bootup time I still believe that it is the right choice since sometimes a lot of clutter and bad things accumulate over time inside the OS and can cause a vast variety of problems in a long run. So stay safe and shut down that PC as it used to be in the past.
