# The Go Programming Language
|
||
|
||
**go-legacy-win7** is a fork of the Go programming language that maintains support for Windows 7 and Windows Server 2008 R2, and allows for deprecated `go get` behaviour. This project aims to provide a stable Go environment for users who need to support legacy Windows systems or prefer the traditional Go workflow.

## Differences from Upstream Go
|
||
|
||
1. **Windows 7 and Windows Server 2008 R2 Support**
|
||
While the official Go project has dropped support for Windows 7 and Windows Server 2008 R2, this fork maintains compatibility with these legacy Windows systems.
|
||
|
||
Tested on Windows 7 RTM (build 7600) — no updates required — through Windows 11 24H2
|
||
|
||
2. **Classic `go get` Behaviour**
|
||
This fork allows for the deprecated `go get` behaviour when `GO111MODULE` is set to "off" or "auto". This means:
|
||
|
||
- In `GOPATH/src`, `go get` and `go install` can operate in `GOPATH` mode.
|
||
- Outside of `GOPATH/src`, these commands can use module-aware mode when appropriate.
|
||
|
||
3. **Compatibility Notes**
|
||
Please be aware that some newer Go features may not be fully compatible with Windows 7 or Windows Server 2008 R2. We try to maintain as much functionality as possible, but some limitations may exist.
|
||
|
||
## Changes in Each Release
|

|
||
|
||
- Switched back to RtlGenRandom from ProcessPrng, which breaks Win7/2008R2 (reverted [693def1](https://github.com/golang/go/commit/693def151adff1af707d82d28f55dba81ceb08e1))

|
||

||
### Before you begin
|
||
To avoid PATH/GOROOT conflicts and mixed toolchains, uninstall any existing Go installation first.
|
||
|
||
#### Windows Installation
|
||
|
||
1. Download the `go-legacy-win7-<version>.windows_<arch>.zip` file.
|
||
2. Extract the ZIP to `C:\` (or any preferred location). This will create a `go-legacy-win7` folder.
|
||
3. Add the following to your system environment variables:
|
||
- Add `C:\go-legacy-win7\bin` (or your chosen path) to the system `PATH`.
|
||
- Set `GOROOT` to `C:\go-legacy-win7` (or your chosen path).
|
||
4. Add the following to your user environment variables:
|
||
- Add `%USERPROFILE%\go\bin` to the user `PATH`.
|
||
- Set `GOPATH` to `%USERPROFILE%\go`.
|
||
|
||
#### macOS and Linux Installation
|
||
|
||
1. Download the appropriate `go-legacy-win7-<version>.<os>_<arch>.tar.gz` file.
|
||
|
||
- For macOS: `go-legacy-win7-<version>.darwin_<arch>.tar.gz`
|
||
- For Linux: `go-legacy-win7-<version>.linux_<arch>.tar.gz`
|
||
|
||
2. Extract the archive to `/usr/local`:
|
||
|
||
```
|
||
sudo tar -C /usr/local -xzf go-legacy-win7-<version>.<os>_<arch>.tar.gz
|
||
```
|
||
|
||
3. Add the following to your shell configuration file:
|
||
|
||
- For bash, add to `~/.bash_profile` or `~/.bashrc`
|
||
- For zsh, add to `~/.zshrc`
|
||
|
||
```bash
|
||
export GOROOT=/usr/local/go-legacy-win7
|
||
export GOPATH=$HOME/go
|
||
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
|
||
```
|
||
|
||
4. Apply the changes:
|
||
|
||
- For bash: `source ~/.bash_profile` or `source ~/.bashrc`
|
||
- For zsh: `source ~/.zshrc`
|
||
|
||
Note:
|
||
|
||
- On macOS Catalina and later, zsh is the default shell.
|
||
- On most Linux distributions, bash is the default shell.
|
||
|
||
After installation, verify the installation by opening a **new terminal** and running:
|
||
|
||
```
|
||
go version
|
||
```
|
||
|
||
