For many Windows users and IT administrators, the release of Microsoft Edge version 135 brought a mix of anticipation and frustration. While the update promised enhanced performance and new features, a significant number of users encountered a perplexing "first-run glitch" that disrupted the browser's initial launch. This issue, often manifesting as an ERR_INVALID_URL message, has sparked widespread discussion in tech forums and enterprise environments. In this deep dive, we explore the root causes of the Edge 135 glitch, provide actionable solutions, and analyze what this incident reveals about Microsoft's update processes and support mechanisms for Windows enthusiasts and professionals alike.

Understanding the Edge 135 First-Run Glitch

Microsoft Edge 135, rolled out as part of a broader update cycle for the Chromium-based browser, was designed to refine user experience with improved security protocols and better integration with Windows 11 features. However, shortly after its release, reports began flooding in about a glitch that prevented the browser from launching correctly on the first run after installation or update. Instead of the familiar welcome screen or homepage, users were greeted with an error message—most commonly ERR_INVALID_URL—indicating that the browser couldn't load its initial page.

This issue appears to primarily affect both individual users on Windows 10 and 11, as well as enterprise environments where Edge is deployed across multiple systems. According to posts on Microsoft’s community forums and feedback on platforms like Reddit, the glitch often occurs when Edge attempts to load a default or custom start page that fails to resolve correctly. Some users speculated that the error ties back to misconfigured network settings or cached data conflicts during the update process, though Microsoft has yet to provide a definitive root cause at the time of writing.

To verify the scope of the issue, I cross-referenced user reports with official Microsoft communications. A thread on the Microsoft Tech Community forum confirmed that the company is aware of the glitch, with a post dated shortly after the Edge 135 release acknowledging "intermittent first-run failures." Additionally, a report from TechRadar highlighted similar complaints, estimating that thousands of users worldwide have encountered the error. While exact numbers remain unverified, the consistency of reports across independent sources underscores the glitch’s significance.

Why the First-Run Glitch Matters

For the average Windows user, a browser glitch might seem like a minor inconvenience. However, the Edge 135 first-run issue carries broader implications, especially for enterprise users and IT administrators who rely on seamless software deployment. In corporate settings, where Microsoft Edge is often the default browser due to its deep integration with Microsoft 365 and Azure Active Directory, a failed launch can disrupt workflows, delay onboarding for new employees, and increase helpdesk tickets.

Moreover, Edge’s role as a critical component of the Windows ecosystem means that glitches like this can erode user trust. With competitors like Google Chrome and Mozilla Firefox vying for market share, Microsoft cannot afford persistent reliability issues. This incident also raises questions about the testing and quality assurance processes behind Edge updates—a topic of recurring concern among Windows enthusiasts who expect robust performance from a browser so tightly woven into the operating system.

Technical Breakdown: What Causes ERR_INVALID_URL?

Let’s unpack the technical underpinnings of the Edge 135 first-run glitch. The ERR_INVALID_URL message typically indicates that the browser is attempting to access a webpage with an improperly formatted or unreachable URL. In the context of Edge 135, this error often appears when the browser tries to load its default start page—either the Microsoft News feed, a custom enterprise homepage, or a user-defined URL—during the initial launch post-update.

Several potential triggers have been identified through community troubleshooting and expert analysis:

  • Network Configuration Issues: If Edge cannot resolve the DNS for the start page due to temporary network glitches or firewall restrictions, it may throw the ERR_INVALID_URL error.
  • Corrupted Cache or Profile Data: Updates occasionally fail to clear or migrate old user data properly, leading to conflicts that prevent the browser from initializing correctly.
  • Policy Misconfigurations: In enterprise environments, Group Policy Objects (GPOs) or Microsoft Intune settings that dictate start page behavior might be incompatible with Edge 135’s updated codebase.
  • Bug in Edge’s Update Mechanism: Some users suggest that the glitch stems from how Edge 135 handles the transition during its first run, potentially tied to a faulty initialization script.

While these theories are plausible, it’s important to note that Microsoft has not officially confirmed the exact cause. A statement on the Microsoft Edge Insider blog mentioned ongoing investigations into "first-run anomalies," but lacked specific details. Without an official root cause analysis, users and IT professionals are left to troubleshoot based on trial and error—a frustrating reality for those managing large-scale deployments.

Solutions for Resolving the Edge 135 Glitch

Thankfully, the Edge 135 first-run glitch is not a permanent roadblock. Community-driven solutions and preliminary guidance from Microsoft offer several workarounds to get the browser up and running. Below are the most effective fixes, verified through user feedback on forums like Microsoft Answers and independent testing reported by outlets such as ZDNet.

1. Clear Cache and Reset Settings

Corrupted data is a common culprit in browser glitches. Clearing Edge’s cache and resetting settings can often resolve the ERR_INVALID_URL error.

  • Open Edge (if possible) or access settings via a secondary browser profile.
  • Navigate to Settings > Privacy, search, and services > Choose what to clear.
  • Select All time and clear browsing data, including cookies and cached files.
  • If the browser won’t open, delete the Edge user data folder located at C:\Users\[YourUsername]\AppData\Local\Microsoft\Edge\User Data (ensure Edge is closed before proceeding, and note that this will erase saved passwords and settings unless synced).

User reports indicate a 60-70% success rate with this method, though it’s less effective in enterprise setups with managed profiles.

2. Check Network and Firewall Settings

Since the error often relates to URL resolution, verifying network connectivity is a logical step.

  • Ensure your internet connection is stable and DNS servers are reachable (try switching to public DNS like Google’s 8.8.8.8).
  • Temporarily disable firewalls or security software that might block Edge’s access to default URLs.
  • If in an enterprise environment, consult with IT to confirm that proxy settings align with Edge’s requirements.

This solution is particularly relevant for users behind corporate networks, where strict policies can interfere with browser initialization.

3. Modify Start Page via Policy or Registry

For enterprise users, adjusting the default start page can bypass the glitch.

  • Use Group Policy Editor (gpedit.msc) to navigate to Computer Configuration > Administrative Templates > Microsoft Edge > Startup, home page and new tab page.
  • Set a specific, accessible URL as the start page or disable the first-run experience entirely.
  • Alternatively, edit the Windows Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge to define a custom start page (exercise caution and back up the registry first).

This method has proven effective in controlled environments, as noted in a Microsoft Tech Community thread with over 200 upvotes for similar fixes.

4. Reinstall Edge or Roll Back to a Previous Version

If all else fails, a clean reinstall or rollback may be necessary.

  • Uninstall Edge via Settings > Apps > Apps & features, then download the latest stable version from Microsoft’s official site.
  • For enterprise users, consider deploying an earlier build (e.g., Edge 134) using the Microsoft Edge Enterprise installer until a patch is released.
  • Note that uninstalling Edge on Windows 11 may require PowerShell commands, as it’s a system app.

While effective, this approach is time-consuming and impractical for large-scale deployments.

5. Await Microsoft’s Official Patch

Microsoft has acknowledged the issue and is reportedly working on a fix. Checking for updates via Settings > About Microsoft Edge may deliver a micro-patch or hotfix. For enterprise users, monitoring the Microsoft 365 Admin Center for deployment advisories is advisable.
