a 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
New users get to try the service completely Free afterwhich it costs $6 per call and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need.

Dazzling_ysi: If you do a project youare supposed to do research and not get the answer handed to you. You can ask for help with it and resources and a solution field is not big enough anyhow to write a "project". But to help you with it, this is a very goodresource on the topic:
Let me citate some lines that I think even answer though shortly your question with FULL credit to the author:
" The advantage of multiple encryption: is that it provides bettersecurity because even if some component ciphers are broken or some ofthe secret keys are compromised, the confidentiality can still bemaintained by the remaining encryptions."
Disadvantage and danger:
" If a multiple encryption has a branch thatends with a parallel block, we are then able to construct an adversaryA that breaks it with only one key exposure query and one decryptionquery.
If a multiple encryption has a branch that ends with a sequentialblock, we may then be able to construct an adversary A that breaks itwith only one key exposure query on the last component and onedecryption query."
For more on the topic please read the pdf.

The latest SPs always contain all of the patches, fixes and security updates (very important) that are released since the last SP. I recommend installing the SP3. I did this on my main developemtn machine and had no problems at all. If you are looking for a real comparison, you'd need to check Microsoft's website to see if they have any information.

This paper presents both theoretical and practical analyses of the security offered by watermarking and data hiding methods based on spread spectrum. In this context, security is understood as the difficulty of estimating the secret parameters of the embedding function based on the observation of watermarked signals. On the theoretical side, the security is quantified from an information-theoretic point of view by means of the equivocation about the secret parameters. The main results reveal fundamental limits and bounds on security and provide insight into other properties, such as the impact of the embedding parameters, and the tradeoff between robustness and security. On the practical side, workable estimators of the secret parameters are proposed and theoretically analyzed for a variety of scenarios, providing a comparison with previous approaches, and showing that the security of many schemes used in practice can be fairly low.

Horrible Operating systems. Unfortunately, if you buy a new computer you are saddled with them. Stay with XP or Win 7. If not, good luck - you will need it! Very steep learning curve.
