No. You have to pay for an update for your pc. It will cost a bit to update your hardware. Some pc updates are free. Even though they are free, they will help improve your computer by quite a bit.
Depends what kind of package and which update. I would recommend buying one off eBay to get the best prices. But make sure to find a software compatible to your computer or you will waste your money.
No, it's free.
If you're looking to get the Windows Update from Microsoft than you can visit the Microsoft website and check their update section. You can also get it from your computer by going to the Start menu, clicking all programs and than clicking on Windows Update.
Nope. The only updates that cost money are if a new operating system comes out and you want to upgrade up (just like going from Windows Vista to Windows 7). But all regular updates will automatically update with no cost.
No, it's just an update.
All updates are free
It doesnt cost any money :)
No. It is part of the OS.

Double-Glazed windows cost much more than conventional windows. They are worth more money because they are much better. However, if you worried about the cost, then buy conventional windows. Easy installation and lower prices. If you want better quality windows, get double-glazed.
