<p data-path-to-node="1">In 2026, Bitdefender users occasionally encounter the <strong data-path-to-node="1" data-index-in-node="54">"Service is Busy"</strong> alert or notice <strong data-path-to-node="1" data-index-in-node="88">High Disk Usage</strong> (often over 90%) in Task Manager. These issues are typically triggered by a <strong data-path-to-node="1" data-index-in-node="180">Background Threat Scan</strong> colliding with a Windows 11 system update or a corrupted <strong data-path-to-node="1" data-index-in-node="260">VSS (Volume Shadow Copy)</strong> service. When the Bitdefender engine attempts to verify a 2026 security certificate during a heavy OS process, the service "hangs," leading to system slowdowns.</p>
<p data-path-to-node="2">For 24/7 technical assistance to resolve "Service Busy" loops, optimize your 2026 disk performance, or to request a refund for a renewal charge, call the expert help desk at <strong data-path-to-node="2" data-index-in-node="174">[phone]</strong>.</p>
