Question details

High-spec Windows PCs managed by Intune experience unusually long load times for applications like Microsoft Teams and Office despite robust hardware.

Fix Slow Microsoft Teams and Office Apps on Intune-Managed PCs

Product: Microsoft Intune and Windows
Device & OS: Windows
Scenario: Launching Microsoft Teams or Microsoft Office applications on Azure-only devices deployed through Microsoft Intune.
Observed behavior: Applications take one to two minutes to open on devices equipped with third-party antivirus, BitLocker, SSDs, and 16 to 32 GB of RAM.

Before you start

Before modifying system registries, ensure you have IT administrator privileges and create a system restore point or registry backup to prevent unintended security or system stability issues.

Solution 1Recommended

Adjust Windows Registry for Policy State

Modifying the VerifiedAndReputablePolicyState registry key can resolve severe application launch delays caused by excessive policy evaluation.

In some Intune-managed environments, Windows Code Integrity (CI) policies aggressively verify applications upon launch. Adjusting this specific registry value often resolves the delay.

Open Registry Editor

Press Windows Key + R, type 'regedit' in the Run dialog, and press Enter to launch the Registry Editor.

Navigate to the Protected Key

Use the left sidebar to navigate to the path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Protected.

Modify the Value

Locate the 'VerifiedAndReputablePolicyState' value on the right pane. Double-click it and change the Value data from 2 to 0, then click OK.

Restart the PC

Restart the computer to ensure the registry changes take effect and test the application launch speed.

Adjust Windows Registry for Policy State

Security Warning: This change alters policy evaluation and might affect system security. Test it on a pilot group before deploying organization-wide via Intune.

Solution 2

Configure Antivirus Exclusions

Ensure third-party antivirus software is not aggressively scanning Teams and Office executables during launch.

Frequently Asked Questions

Why is Microsoft Teams so slow to open on my newly deployed Intune PC?

This typically occurs in Intune-managed environments if Windows Defender Application Control (WDAC) or specific Code Integrity policies are rigorously evaluating applications at launch. Third-party antivirus scanning can also contribute to this delay.

How can I deploy the registry fix to all Intune devices at once?

You can create a PowerShell script that modifies the VerifiedAndReputablePolicyState registry key and deploy it as a proactive remediation script or a Win32 app through the Microsoft Intune admin center.

Will changing VerifiedAndReputablePolicyState to 0 compromise device security?

Modifying this key alters how Windows evaluates Smart App Control and certain Code Integrity policies. You should consult Microsoft documentation and your organization's security team to fully understand the impact before deploying this fix widely.

Can network issues cause Office applications to crash or load slowly?

Yes. If applications rely on cloud connectivity and network geo-blocking or strict firewalls restrict necessary telemetry or update servers, the applications might hang, load slowly, or fail to install correctly.
