The ERR_BLOCKED_BY_ADMINISTRATOR error in Google Chrome means a Windows Group Policy or enterprise policy is preventing Chrome from loading a website or running normally. This typically happens on work or school computers where an IT administrator has set restrictions, but it can also appear on personal PCs due to leftover policy settings, third-party software, or malware. In most cases you can resolve it by clearing enforced policies, adjusting registry settings, or removing software that injected the restrictions.

How to Fix Error Code ERR_BLOCKED_BY_ADMINISTRATOR

  1. Check Chrome's Policy List

  2. Check If You Are on a Managed Device

    If this is a work-issued or school-issued device, do not attempt to change group policies or registry settings without permission from your IT department, as doing so may violate your organization's acceptable use policy.

  3. Remove Rogue Chrome Policies via the Registry

    Editing the Windows Registry incorrectly can cause system instability. Back up the registry before making changes: in Registry Editor, click File > Export and save a backup file to your desktop. Only delete the Google\Chrome and Chromium policy keys — do not delete other entries.

  4. Remove Policies via the Group Policy Editor (Windows Pro/Enterprise)

    The Group Policy Editor (gpedit.msc) is only available on Windows Pro and Enterprise editions. Windows Home users should skip this step and rely on registry editing instead.

  5. Run Chrome's Cleanup Tool

  6. Scan for Malware with Windows Defender or a Trusted Antivirus

  7. Reset Chrome Settings to Default

  8. Reinstall Google Chrome

    Uninstalling Chrome will remove your local browsing data if it was not synced to a Google account. Sign in to Chrome before uninstalling to ensure your bookmarks, passwords, and history are backed up to your Google account.

When to Call a Professional

If this error appears on a company-issued or school-issued device, contact your IT helpdesk — they control the policies and are the only ones who can legitimately remove them. If you have cleared all registry keys, run malware scans, and reinstalled Chrome but the error still appears on a personal PC, a local computer technician can perform a deeper system audit to identify persistent malware or rootkits that may be re-injecting the policies. Also seek professional help if you are uncomfortable editing the Windows Registry.

Frequently Asked Questions

Why am I getting ERR_BLOCKED_BY_ADMINISTRATOR on my personal computer?
Even on personal computers, this error can appear if malware or a third-party program (such as an antivirus, parental control app, or adware) has written Group Policy restrictions into your Windows registry. It can also be left over from a previous work enrollment. Clearing the Google Chrome policy registry keys and running a malware scan typically resolves it.
Can I fix ERR_BLOCKED_BY_ADMINISTRATOR on a work laptop?
Only your IT administrator can fix this on a managed work device. The policies are intentionally set by your organization to control which sites or features employees can access. Attempting to remove them on your own could violate your company's IT policy. Submit a request to your IT helpdesk explaining which site or feature is being blocked.
Will resetting Chrome remove my bookmarks and passwords?
No. A Chrome settings reset does not delete your bookmarks or saved passwords. It resets startup pages, the new tab page, default search engine, pinned tabs, and disables extensions. However, for extra safety, make sure you are signed into your Google account before resetting so your data is synced to the cloud.
How do I know if Chrome policies were installed by malware?
Go to 'chrome://policy' in your browser. If you see policies listed that you did not intentionally set and your computer is not managed by an organization, it is very likely they were injected by malware or unwanted software. Running Chrome's built-in cleanup tool and a full malware scan should remove the source.
Does ERR_BLOCKED_BY_ADMINISTRATOR affect all websites or just specific ones?
It depends on how the policy was configured. An administrator (or malware) can block specific URLs, entire categories of sites, or even Chrome features globally. If only certain sites are blocked, check 'chrome://policy' for a URL blocklist entry. If Chrome itself cannot load at all, the restriction is likely at a broader level such as the executable being blocked by software restriction policies.
