Hello Deepak Mundravale,
The message does not necessarily mean that an organization controls your PC. It can also appear when a local policy or privacy tool has changed the diagnostic-data settings.
First, please confirm your Windows edition by pressing Windows + R, entering winver, and checking whether it is Windows Home or Pro.
Also check Settings > Accounts > Access work or school and confirm that no unexpected account is connected.
If you use Windows Pro:
- Press Windows + R, enter gpedit.msc, and press Enter.
- Open Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds.
- Set Allow Diagnostic Data and Configure diagnostic data opt-in settings user interface to Not Configured.
- Restart Windows and check the setting again.
If you use Windows Home, or these policies are already not configured, please mention whether you recently used any privacy, debloating, telemetry-blocking, or system-tuning tool. Such tools can apply the same restriction through the registry.
