This could cause certain Windows applications <em>—</em> particularly those related to the Microsoft store as well as operations related to Windows updates <em>—</em> to fail to run following bare metal recovery or Windows replica restore. This issue occurs in otherwise successful restore operations. <br> </p> <h2 data-id="resolution"><strong>RESOLUTION</strong></h2> <p>To prevent possible issue, customers that are protecting Windows 2010 and/or Windows Server 2016 via bare metal are strongly encouraged to update their Windows agent to version 10.3.1. Upon updating to agent 10.3.1 the Unitrends backup will be promoted to a full.<br><br>Agent links are below. These agents will also be present in the appliance samba share after updating paid license appliance versions to 10.3.1-3 or higher. <br><br><u><a rel="nofollow" href="/home/leaving?allowTrusted=1&target=ftp%3A%2F%2Fftp.unitrends.com%2Fbp%2F10.3.0-4%2FUnitrends_Agentx86.msi">32-bit Unitrends agent v.10.3.0-4 for Windows 10 and Server 2016</a><br><br><a rel="nofollow" href="/home/leaving?allowTrusted=1&target=ftp%3A%2F%2Fftp.unitrends.com%2Fbp%2F10.3.0-4%2FUnitrends_Agentx64.msi">64-bit Unitrends agent v.10.3.0-4 for Windows 10 and Server 2016</a></u></p> <h2 data-id="cause"><strong>CAUSE</strong></h2> <p>Unitrends has identified a change in the way that Microsoft distributes patch updates for Windows 10 and Windows Server 2016. Hard links may be created associated with temp files after a <a rel="nofollow" href="/home/leaving?allowTrusted=1&target=https%3A%2F%2Fsocial.technet.microsoft.com%2Fwiki%2Fcontents%2Farticles%2F43406.windows-servers-patching-best-practices.aspx">Windows update</a> is applied if the updated system is not rebooted prior to the next scheduled backup. If these temp files are not included as a part of an incremental file level backup, issues with hard links can cause a bare metal restore not to boot properly. To ensure that our customers are protected, a special Windows agent has been created as version 10.3.1-3. <br> </p> <h2 data-id="notes"><strong>NOTES</strong></h2> <p>Following agent upgrade, some caveats related to Windows hard links still apply: </p> <ul><li>If deleted hard links were present in the recycle bin when the backup was taken, Windows replicas <em>—</em> when booted to Audit or Live mode <em>—</em> may display an error message stating that the recycle bin is corrupted. This error message asks if you want to empty the recycle bin. Click <b>Yes</b> to clean up the corruption.</li> <li>Full backups of Windows 10 assets (though this may also affect other Windows versions) may complete with the following error message: "The process cannot access the file because it is being used by another process." Furthermore, these backup jobs may take longer than expected to complete. </li> <li>If issues persist, it may be necessary to reinstall the application following recovery. </li> </ul><br> </article> </main>
