I am running the Window 7 currently. But it have lots of function that i do not like. Acutely i have to do only the basic Microsoft office work on it. So i did not like the version now i want to do back to the Window XP is there any way so i can do that.

Can anyone help with sole this issue I am waiting friends give answers fast.

I wish to enquire if True Crypt is still a secure option for Windows OS XP. I am curious to know if I have to decrypt my systems and eventually updating my hardware soon, most importantly the Mobo, CPU, Heat Sink Fan, Memory and GPU. I would also like to know if True Crypt keeps a system stable when the PC is fully shut down and no root log other than being presented with the password screen to go past the presented screen. 

I have found that Windows XP is not supported on 3rd Gen i5 Processors. Why is it so? Almost all OS like Windows 7,8.1 ,8, Linux, Ubuntu are supported but why not Windows XP? What is the reason behind the incompatibility of Windows XP with 3rd Gen i5 Processors? What can be done for developing the support?

I bought a new machine that contains the Windows XP operating system. But this computer did not come with its operating system CD and now i am experiencing slowness, difficulty in shutting down etc. The question i have now is that how can i reinstall windows XP without a cd? This is because i want to remove the old windows i had in my computer for restore my computers speed, functionality etc.

There were many PCs which were powered by Windows XP and there are many still but I can't figure out why the Windows XP support was ended by MS. There are many people in poor countries which run their PCs in Windows XP since their specs are really low compared to others. Then why did MS forget some of its users?

After using my computer this morning, i just decided to shut it down after a long time of not shutting the computer down. On coming back to power on the computer, i realized that my computer won't let me login to my account. What could be the problem and what can be the possible solution to this problem?

I have a 32GB flash drive that I want to partition so that I can store sensitive files onto a smaller partition and lock it. is this possible? How would I partition the drive so that I can achieve a smaller partition of 4 GB for my personal files and encrypt this portion only?

I would wish to know how to change the interrupter request and to know if the change of this can affect my computer. Can it make it work faster on the devices listed? What is the implication of making the USB devices listed before most peripherals? Can my printer respond faster if I give it a lower value say IRQ 5?
