Rights
- Installing O&O SafeErase requires administrator rights.
- In the program, cleaning free space, erasing drives and partitions, setting up Fortress Mode and changing the Recycle Bin integration require administrator rights. The program offers Restart as administrator where needed.
Fortress Mode
Fortress Mode, which is needed to erase the system drive and the entire PC, runs in the Windows Recovery Environment (Windows RE). If Windows RE is switched off or missing, the setup can repair it. If BitLocker protects the system drive, keep the recovery key at hand.
Browsers
O&O SafeErase cleans these browsers from the listed version on, including later versions:
| Browser | From version |
|---|---|
| Google Chrome | 115 |
| Microsoft Edge | 115 |
| Mozilla Firefox | 115 |
| Brave | 115 |
| Opera, Opera GX | 101 |
| Vivaldi | 6 |
Only the stable releases of Brave, Opera, Opera GX and Vivaldi are supported. Internet Explorer and the earlier Edge (Legacy) are not cleaned.
File systems
When cleaning free space, Erase cluster tips (DeepErase) works on NTFS drives only. Clean up references in the MFT treats the MFT on NTFS drives and the directory entries on FAT drives. Erasing drives and partitions works independently of the file system.
