Game centers, Internet cafes and universities all have reborn cards installed in PCs.
Reborn-card will wipe out any installed programs by users at bootup and return to the Day 1 installed configuration. Good for preventing viruses and malicious codes and to ensure all the default configurations are not changed in any way.
For universities, people think that there might be a need to set aside a special partition to store user data where the data will remain intact upon bootup. Hey....man, I rather think that with the emergence of USB memory finger at extremely low cost, it is redundant to consider such a common partition.
