Use the user-data directory root—not a profile subfolder such as Default—and do not run another Chrome process against that same directory at the same time.
Minimal Windows example
Install Puppeteer in your Node.js project, then save this as screenshot.js. Replace the illustrative profile path with a directory your Windows account can write to.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({
userDataDir: 'C:\Users\YourName\AppData\Local\Puppeteer\ChromeProfile',
});
try {
const page = await browser.newPage();
await page.goto('https://example.com', { waitUntil: 'networkidle2' });
await page.screenshot({ path: 'capture.png', fullPage: true });
} finally {
await browser.close();
}
})();Run it from the project directory with node screenshot.js. The example waits for network activity to settle before capture and saves a full-page PNG as capture.png in the current working directory. Puppeteer documents userDataDir as a launch option in its LaunchOptions interface. Chromium’s equivalent Windows command-line setting is chrome.exe --user-data-dir=c:\foo (Chromium User Data Directory).
User-data directory versus Chrome profile folder
userDataDir identifies the browser’s user-data root: the directory that holds Chrome’s profile data. It is not usually the individual profile directory beneath that root, such as Default or Profile 1. Give Puppeteer the root directory you want it to use; Chrome manages the profile data inside it.

The path in the example is only illustrative, not a required Windows location. Choose a dedicated automation directory and ensure the account running the script has write access. Avoid pointing automation at your everyday Chrome data: a separate directory makes the automated session independent and avoids contention with normal browsing.
Choose the browser executable
With the standard puppeteer package, Puppeteer downloads a compatible Chrome for Testing browser by default. That is the simplest choice when you do not need to control Chrome separately. If you use a separately managed Chrome installation, set executablePath in the launch options, for example:
const browser = await puppeteer.launch({
executablePath: 'C:\Program Files\Google\Chrome\Application\chrome.exe',
userDataDir: 'C:\Users\YourName\AppData\Local\Puppeteer\ChromeProfile',
});The path shown is an example; use the actual location of the executable on your system. Puppeteer guarantees compatibility only with its bundled browser, so a separately updated Chrome gives you update control but also makes browser-version compatibility your responsibility. The official installation guide explains browser installation; puppeteer-core does not download Chrome. If package installation scripts were blocked and the bundled browser was not installed, the guide documents npx puppeteer browsers install as a manual installation step.

Save the capture you need
Puppeteer’s screenshot API is Page.screenshot() (Screenshots guide). Choose the capture mode based on the output you need:
Quick wins for a faster PC:

|---|---|---|
| Save an image file | path: 'capture.png' |
Writes the screenshot to that path. If path is omitted, the API returns image bytes instead. |
| Capture the full page | fullPage: true |
Captures beyond the current viewport. |
| Capture a specific region | clip |
Restricts capture to the specified rectangle. |
| Capture one element | Call screenshot() on its ElementHandle |
Captures that element; Puppeteer’s guide says it tries to scroll a hidden element into view. |
PNG is the documented default image type. The quality option applies to image formats other than PNG. See the ScreenshotOptions interface for the current option details.
Fix common Windows launch failures
Chrome says the profile is already in use
Puppeteer checks for a Windows profile lock. If another Chrome process is using the same userDataDir, stop that process or choose another directory, then retry. Do not try to make two active Chrome sessions share the automation profile. The lock handling is visible in Puppeteer’s BrowserLauncher source.

The profile cannot be written
Use a directory writable by the Windows account running Node.js. Check the path, folder permissions, and whether a security policy or another process is preventing access. Puppeteer distinguishes an unwritable profile from an already-running browser, so follow the actual launch error rather than treating both as the same problem.
Chrome fails under an organization extension policy
Puppeteer passes --disable-extensions by default. The troubleshooting guide notes that some Chrome policies enforce extensions and can conflict with that default; for that policy conflict, it documents enableExtensions: true as a workaround:

Pick the symptom - the matching free tool is one click away.
const browser = await puppeteer.launch({
userDataDir: 'C:\Users\YourName\AppData\Local\Puppeteer\ChromeProfile',
enableExtensions: true,
});Use this only when the reported failure matches the extension-policy issue. Details are in Puppeteer’s Troubleshooting guide.

Downloaded Chrome reports a sandbox permission error
Puppeteer’s troubleshooting documentation says that, beginning with v22.14.0, installation attempts to configure Windows sandbox permissions using Chrome’s setup.exe. Verify your Puppeteer version and the exact error before changing permissions. For older installations or persistent errors, the guide documents an icacls command for the Puppeteer Chrome cache and recommends the more restrictive SID in high-security environments. Follow the instructions for your specific case in the official troubleshooting guide rather than applying broad permission changes.
The Chrome executable is missing
If you use puppeteer-core or manage the browser yourself, install a browser and provide its path with executablePath. The regular puppeteer package normally downloads a compatible browser; if that step was skipped, use the manual browser-install command described above.
Or skip the browser setup
For a screenshot from one request, ScreenshotNeo avoids managing a local Chrome installation or user-data directory. Its API accepts a URL and returns an image or PDF. For example, save a WebP capture with cURL:

Frequently Asked Questions
Does Puppeteer support a custom Chrome user-data directory on Windows?
Yes. Pass the directory as the userDataDir option to puppeteer.launch().
Can two Chrome processes use the same Puppeteer user-data directory at once?
No. Close the process holding the profile lock or launch Puppeteer with a different directory.
