My brother had been using my PC for watching movies and play games and I wanted to work, so I installed archlinux without any DE or WM, now if he tries to use it he might learn thing or too or leave my PC alone!!!!

Normal people set a password.

@Maer lol I have tried that but he once saw me bypassing the windows password with Windows bootable disk, and then few days later with the help of Internet he starting bypass passwords too but Linux is kind a different domain for him right now and if he learns Linux by this it's a win-win.

he prob will install windows on ur pc

@gustiyoga for which he had to reformat linux ext4 partition into windows ntfs and that way he will loose my data (and I told him that my imp work related data is on that computer so he will not try to format the drive) until and unless he finds my external hard drives and backups my data and then installs Windows. Shit.
