There are not many applications for creating mind maps, even fewer that are completely free, so it is with great pleasure to present you with Freeplane. Freeplane is mind mapping, Knowledge Management, and Project Management software completely free and open source.
You can it here: https://sourceforge.net/projects/freeplane/files/latest/download
Freeplane is a free and open-source software application that supports thinking, sharing information, and getting things done at work, in school, and at home. The core of the software is tools for mind mapping (also known as concept mapping or information mapping) and using mapped information. Freeplane is written in Java using OSGi and Java Swing. It runs on any operating system that has a current version of Java installed. It can be run locally or portably from removable storage like a USB drive.
We use Github only as of the main code repository, all other project parts are hosted at the source forge. So all bugs and feature requests are managed in a separate issue tracker. There is a drop-down box for selecting different types of issues. Other sources of inspiration are our new forum and old forum. Some users write their ideas there. Every contributor and every team member freely decides what task he is going to work on, but for making the best decision we can communicate our self-set goals in the above forum. It is supposed to enable early discussions and community feedback and also to motivate you and other people.
People new to the project can start with implementing a new small feature or doing some refactoring or documentation and not with the bug fixing. Not all bug reports seem to be equally important, and if there are important bugs they usually get fixed by people who broke the functionality. I think you should first get there :).
For internal developer discussions, there is a private mailing list. It is held private to avoid spam mails. If you want to be subscribed let us know what mail address you are going to use with it. This list is the preferred way to ask all code-related questions because they usually get answered soon and by the most competent team member.
Some documentation for new developers is available in Freeplane wiki https://www.freeplane.org/wiki/index.php/How_to_build_Freeplane and also here and here. It is written for new guys and should also be maintained by the new guys to stay up to date.
Looking forward to any questions and contributions,
Freeplane development team

Error Causes“Sfc /scannow”
Error 0xc0000142 can occur in any of the Windows versions and usually occurs when an application fails to properly initialize.
This error can be critical for a computer as it signifies that the system is unstable. Error 0xc0000142 can cause slow performance in a PC, system freeze, startup and shutdown issues, blue screen and errors in installation.
Error CausesWindows/Application Error 0xc0000142 can occur because of a number of reasons.
When a computer is an overload with data, or when system files get broken or missing, this error can occur and will result in startup and shutdown issues as well as the blue screen. Another reason, and one which is quite common, is improper computer maintenance.
This will cause a PC to perform slow, system freezes, and installation errors. This error displays ‘failed to initialize’ on either a Windows error box or the blue screen of death.
Error 0xc0000142 can occur at any time, but there are many ways to resolve it. For instance:
A corrupted registry is one of the major reasons why this error occurs. The registry is used by Windows to store information and settings on the computer, which is why it has a large database.
This database contains emails, wallpapers, saved passwords and much more in ‘file path references’. These allow Windows to run the common files in your system. A registry cleaner can fix any errors in the registry database.
Viruses can cause certain applications to not function properly. Hence, download a strong antivirus and run a deep scan on your system and remove any potential infections and spyware.
Non-critical applications in a computer are those that are installed by the user. If error 0xc0000142 displays in any of your installed programs, then you should reinstall these programs. Often applications have damaged or corrupted files which can slow them down. To resolve this, follow these steps:
The third step is not recommended in case the error is caused by cmd.exe
If the error is still on display despite following the previous steps, then you can repair Windows. This process allows Windows to retain all your data and information by simply replacing the program files and settings with fresh ones. This can stop error 0xc0000142 by allowing the programs access to use necessary files smoothly and effectively.
If you cannot resolve the error in any of these steps, then there is another way to do so if you have a computer that runs the Microsoft Internet Security and Acceleration (ISA) Server 2000. Follow these steps in order to resolve it:
“Something went wrong, We weren’t able to set up your PIN. Sometimes it helps to try again or you can skip for now and do this later.”On the other hand, here’s the error message you get for the Microsoft Store-related error:
“Try that again, Something happened on our end and we couldn’t sign you in.”Here are some potential fixes you can try to fix the Error Code 0x80090016 in the Microsoft Store:
powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRootWinStoreAppxManifest.xml
“This policy setting allows you to control whether a domain user can sign in using a convenience PIN. If you enable this policy setting, a domain user can set up and sign in with a convenience PIN. If you disable or don’t configure this policy setting, a domain user can’t set up and use a convenience PIN. Note: The user’s domain password will be cached in the system vault when using this feature. To configure Windows Hello for Business, use the Administrative Template policies under Windows Hello for Business.”
powercfg –lastwakeOnce you enter the command given above, it will show you the last device that woke your PC up. After that, you need to type in the next command:
powercfg –devicequery wake_armedAfter entering the command, it will show you a list of all the devices that could wake your PC up. The goal in running these commands is to understand the reason what’s really causing your PC to turn on and see the reason is on the hardware level or not. Here are a couple of options you can try if your Windows 10 PC turns on by itself.
“Something went wrong, Sorry, installation cannot continue because no compatible office products are detected.”When you have to work on two different languages, that’s where the language packs come in handy. You might have to work on one language but when it comes to proofreading or help, you need another language. Note that some language accessory packs offer partial localization which is why some parts of the Office might show the default language. If you are using Office 365 or Office 2019, 2016, 2013, or 2010, you need to go to the language accessory pack page from office.com and select your language. Once you see the download link, click on it to start downloading the pack. It includes the display in the chosen language, proofing tools for the selected language, as well as the Help in the selected language. Once the installation is complete, follow each one of the given options below to configure the language accessory pack properly.
The feature that was originally planned for now scrapped Windows 10X is included in Windows 11. You will be able to customize your Virtual desktop with different wallpapers for each screen.
In order to fully customize your virtual desktops with different wallpapers follow this easy step-by-step guide.
