Thank you for posting your question in the Microsoft Q&A forum.
Regarding your issue, may I kindly ask a few questions to help understand your issue better
- What is actively syncing right now? Is it related to OneDrive/SharePoint, Microsoft Account settings, or something else?
- What is the specific process name in Task Manager? (e.g., CDSSync, OneDrive.exe, etc.)
- When does the heavy usage occur? Only after sign-in, during file transfers, or constantly in the background?
- How long has this been happening?
- Have you made any recent changes to your system? Did you install updates, add a new device, or enable sync settings recently?
Hope to hear back from you soon.
The initial response may not fully address your needs, but it will help me better understand your situation. Once I get the information, I will try my best to find the next steps.
