Well, without harming your computer, i would say that everything is risky. Reinstall your Operating System, but before you reformat and reinstall the OS. Backup all your important files on CD and Email, and another computer. Once you reinstall, the virus will be completely gone, risk-free.
yes
To reinstall Windows, you can use a dedicated installation partition, typically known as the "Recovery Partition." This partition contains files necessary for restoring or reinstalling the operating system without needing external media. Alternatively, you can create a bootable USB drive or DVD with the Windows installation media, which allows for a fresh installation on the primary system partition. Both methods enable you to reinstall Windows while retaining or formatting other partitions as needed.
Yes.
Any application not written for Windows can be used without Windows.
If your restore requires a windows disk then you cannot restore without one. Most do not require a windows CD. Most include the windows files in the manufacturer restore.
Yes, if you have copied all installion files on your hard disk. If you haven't you cannot reinstall Vista.
You can activate Windows automatically without calling if you are connected to the internet, assuming your hardware hasn't changed.
Partitioning allows you to create a logical separation between different operating systems and data. For example, you could have a windows operating system on one partition, a Linux operating system on another partition, and your personal data (My Documents in windows and /home in Linux) on a third. This allows you to wipe one of your partitions clean and reformat without having to backup the data on the others (say for example, your windows install gets a virus).
Reinstall the operating system or if you have the password simply reset it at "Control Panel".
you have to boot from something else, whether it be a floopy disk, thumb drive, or setup cd. you can't delete files that you are currently using. if you boot into windows xp you can't delete windows xp.
If you are talking about programs, you can't. If you create a dual boot system, the programs will have to be installed on each operating system (actually the program does not reinstall but it does register the files for each of the operating systems). Data files don't care where you put them. You may have to search for a known file name to find them.
