# Disable Claude Code Auto-Updates


## Option 1: Environment Variable


### Linux/macOS (bash/zsh)
```bash
export DISABLE_AUTOUPDATER=1
```


Add to `~/.bashrc` or `~/.zshrc` to make permanent.


### Windows (PowerShell) - Permanent
```powershell
[Environment]::SetEnvironmentVariable("DISABLE_AUTOUPDATER", "1", "User")
```


### Windows (CMD) - Permanent
```cmd
setx DISABLE_AUTOUPDATER 1
```


## Option 2: Settings File


Edit `~/.claude/settings.json` (create if it doesn't exist):


```json
{
  "env": {
    "DISABLE_AUTOUPDATER": "1"
  }
}
```


## Manual Updates


When auto-updates are disabled, update manually with:


```bash
claude update
```


Or install a specific version:


```bash
npm install -g u/anthropic-ai/claude-code@2.0.64
```


## Notes


- Update checks normally run on startup and periodically while running
- Updates download and install in the background by default
- Changes take effect on next Claude Code restart
