Compatibility
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
Bitcoin Core is extensively tested on multiple operating systems using
|
|
|
|
|
the Linux kernel, macOS 10.8+, and Windows Vista and later.
|
|
|
|
|
|
|
|
|
|
Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support).
|
|
|
|
|
No attempt is made to prevent installing or running the software on Windows XP, you
|
|
|
|
|
can still do so at your own risk but be aware that there are known instabilities.
|
|
|
|
|
Please do not report issues about Windows XP to the issue tracker.
|
|
|
|
|
|
|
|
|
|
Bitcoin Core should also work on most other Unix-like systems but is not
|
|
|
|
|
frequently tested on them.
