Learn how to review running processes in Windows 11, identify warning signs, and investigate suspicious activity without guessing from a process name alone.
Press Ctrl + Shift + Esc to open Task Manager. The Processes tab shows running apps and background processes along with CPU, memory, disk, and network usage. The Details and Services views can provide additional context.
Do not treat an unfamiliar process name as automatic evidence of infection. Look for context: where the executable came from, whether its resource or network behavior is unusual, whether it appeared unexpectedly, and whether other security evidence supports concern.
A useful investigation can connect process activity with network connections, startup behavior, services, scheduled tasks, persistence evidence, Defender/Firewall status, and recent system changes. Sentinel AI is built to correlate that kind of Windows evidence and preserve investigation history rather than forcing the user to interpret one raw list at a time.
Sentinel AI is a Windows security suite built around continuous monitoring, investigation, evidence correlation, containment, quarantine, remediation, optimization, and clear guidance. It works alongside Microsoft Defender rather than replacing the antivirus engine. Defender remains responsible for antivirus and antimalware scanning; Sentinel adds the broader investigation and response workflow around Windows system and security evidence.

No. High resource use can have many legitimate causes. Treat it as a clue that may deserve investigation, not proof of malware.
Yes. Task Manager shows apps and background processes and their resource usage, and it includes additional Details and Services views.
Sentinel AI is designed to correlate process evidence with other system and security signals, preserve investigation history, and support verified containment or remediation when appropriate.

In Task Manager, right-click a process and choose Open file location where available. Examine the folder path and file properties, including any digital signature. A familiar-looking name is not enough to prove a file is safe, and an unfamiliar name is not proof of malicious activity.
Consider whether the process starts unexpectedly, persists after a restart, makes unexplained network connections, or appears alongside browser redirects or account-security alerts. A single CPU spike can come from an update, a browser tab, or legitimate software. Multiple related signals deserve closer inspection.
Open Windows Security, review Protection history, update security intelligence, and run a Microsoft Defender scan. For stronger suspicion, consider Microsoft Defender Offline scan after saving your work. Do not delete system files or disable security services merely because a process name looks unusual.
Write down the process name, file path, timestamp, and observed behavior. Screenshots of Task Manager, Windows Security alerts, and relevant Event Viewer entries can help you compare events. Sentinel AI is intended to complement Defender by bringing monitoring and investigation signals together; it is not a replacement for antivirus scans.

Unfamiliar process names are common, so verification matters more than guesswork.
Open Task Manager, review the process and its publisher where available, and use Open file location to inspect the executable path. Check whether the application was recently installed and whether it has a legitimate reason to run.
A familiar name can be impersonated. Conversely, a strange-looking helper process may be a normal part of Windows or an installed app. Evaluate behavior, signature, path, and related alerts together.
If you suspect malware, disconnect from risky activity, run a Defender scan, and preserve relevant details. Avoid deleting Windows files based on a name alone.
