Short answer: Use elevation only when needed for drive access, and treat the resulting ability to change protected files with care.

When this guide is useful
On a shared PC, another user's profile may be outside your permission scope. Permission to diagnose disk pressure does not automatically authorize reading another person's documents or exporting their filenames.
Recommended workflow
- Try the scan in your approved user context.
- Check whether important folders are inaccessible.
- If authorized, repeat with elevation.
- Compare the coverage rather than assuming the first result was complete.
Limits and precautions
Administrator rights increase the consequences of a mistaken delete operation.
Keep a useful record
Record the drive or folder, scan time, application version and the measurement you used. Keep observations separate from proposed changes. If a result leads to a cleanup, record the file owner, backup status and actual free-space change. This makes the result easier to review and helps explain differences in a later scan.
Quick review checklist
| Question | What to record |
|---|---|
| What did you inspect? | The exact volume or folder, not just the PC name. |
| What action is justified? | Compare the coverage rather than assuming the first result was complete. |
| What could go wrong? | Administrator rights increase the consequences of a mistaken delete operation. |
Next steps
If the result is unclear, preserve the current report and narrow the investigation to one folder or application. Make one approved change at a time, then repeat the relevant measurement. Avoid presenting a predicted saving as a measured outcome.
