Microsoft has resolved launch issues for certain apps on Windows 10 22H2 following the September 2024 preview cumulative update. Non-admin users may encounter failures with apps like Quick Assist and Teams. A Known Issue Rollback (KIR) will automatically apply the fix, with guidance available for enterprise-managed devices.
### Meeting Takeaways:
1. **Issue Description**:
– Microsoft has addressed a known issue affecting app launches for non-admin users on Windows 10 22H2 systems after the September 2024 preview cumulative update (KB5043131), released on September 24, 2024.
– Apps like Quick Assist, Microsoft Teams, and Windows Narrator may fail to start due to child processes running with low Integrity levels instead of medium.
2. **Affected Applications**:
– Any app with the attribute `UIAccess=true` in its manifest can experience startup issues when run by non-admin users. This includes specific secure paths: ProgramFiles folder, %systemroot%\system32, and %systemroot%\syswow64.
3. **Resolution**:
– While a complete fix is forthcoming via Windows Update, Microsoft has implemented a Known Issue Rollback (KIR) to address the problem immediately.
– The KIR fix will automatically propagate to home and non-managed enterprise devices within 24 hours.
4. **Enterprise Deployment**:
– For Windows enterprise-managed devices, administrators must manually install the KIR Group Policy.
– This involves accessing either the Local Computer Policy or Domain Policy via the Group Policy Editor, selecting the target Windows version, and restarting affected devices to apply the policy.
5. **Additional Context**:
– This is not the first time Microsoft has utilized KIR; similar rollbacks were performed in August and July 2024 to resolve performance and automation issues in Windows Server 2019 and Windows 11, respectively.
6. **Further Guidance**:
– Microsoft has published additional support documentation on deploying and configuring KIR Group Policies on their website.
### Action Items:
– Ensure all devices are updated with the KIR fix.
– For enterprise IT teams: Review and deploy the KIR Group Policy as necessary.
– Monitor the Windows health dashboard for further updates.
