Wipe the Computer Clean in Windows 7 without a disc is hard to understand, how could one wipe hard drive entirely when Windows 7 is running, I mean how to erase the operating system when you are running programs in it? Years ago, it may be difficult for software companies to wipe a computer clean without a CD, but now, with the help of Macrorit Disk Wiper, we can wipe the whole disk including System Partition without a disc.
1. Download Data Wiper Portable Edition, since we are doing wipe job, so you don't have to install more software, just download the portable edition, run it without installation;

5. Click Wipe Now;
6. Click Yes when warning message shows;
7. Type WIPE to Confirm.

Warning: Data Wiper removes everything (include personal information and the recovery partition) on the disk if you select the **Entire drive** option, no matter the disk is HDD, SSD, or USB flash drive, it's not factory reset Windows, it's wiping it, you cannot use Windows again unless you reinstall the operating system.
Maybe you will ask: what's the status of the disk after the above steps? it's RAW disk, or you can call it Factory settings of the disk. If you are going to reinstall a clean system, a RAW disk is needed; or you can set the disk to factory settings before donating or reuse. Nothing is in there, that's the fastest way to set restore disk to factory settings without a disc.
People we reuse your disk would ask a disk with an original state so that they can make a clean installation on it. Clean wipe is to ensure a clean installation. Traditional ways to wipe hard drive requires a bootable CD, windows installation disc, and complicate commands if you want to install new Windows System.
