How to kill Windows XP Professional edition sp3 without the possibility of recovery (Live CD and others)?

Question

Windows

Good afternoon everyone!
Interested in the question of how to kill Windows XP Professional edition sp3 without the possibility of recovery (Live CD and other manipulations), there is root access. I ask you to omit ethical moments right away - there is a sports dispute here. Tips to kick your foot in the HDD area and other wrecking advice on hardware are not good :). Only software - only hardcore. I myself have already tried to demolish different files and libraries = the system stops booting, but this is easily cured by Live CD - that's why the option is needed for sure and finally. Thank you.

Answer 1

You can overload and boot from a USB flash drive / disk.
I mean that user 1 works and has full access, can reboot the PC and do whatever he wants programmatically, BUT the point of no return should come after a few more reboots when user 2 is already working (so that they don’t think about user 1 - the moment of secrecy of manipulations is important) - I think the task scheduler in Windows itself can do?

Answer 2

So from a Live CD, you can simply reinstall the system. You can't do anything against it.
But you can try to wipe the first few sectors of the disk with zeros to clog the boot sector and markup, up to the root directory of the first partition.
Restoring files from broken ntfs is not a task for livecd.
Regularly, you can do one more thing: encrypt the file system on the system disk, with a pincode on the flash drive, "lose" the flash drive, respectively.

Answer 5

If you can not reload and boot from a flash drive / disk:
0. Create a new user and log in under him;
1. Remove all programs in the "Installing and Removing Programs";
2. Delete the %systemroot%\system32\config folder - these are the Software, System, and Security registry keys;
3. Delete the Ntuser.dat files from the folders of all users;
4. Delete all files from the desktop of all users;
5. Search for all media files and delete;
6. Start deleting the Windows folder as far as it goes.
If you can boot from a USB flash drive, then the advice of Axian Ltd.about wipe hdd it's the most. Boot from any Recovery Disk/Recovery Flash that should have a utility to clean up the hard drive.
