Other types of updates correct errors or enhance functionality within Windows, and are not necessarily security related.
Protecting Your Computer To ensure that the latest Windows updates are downloaded and installed, you should check that your computer is set up as follows: You will generally receive a notification from Microsoft in the form of an alert on your screen, that Windows updates are available.
We can of course go for a 64-bit version of Windows, but even today, there is still quite a lot of software which cannot run properly on x64, which can be inconvenient if you’re someone like us who installs and tests a lot of software.
Not only that, Windows 64-bit doesn’t accept unsigned drivers unless you disable driver signature enforcement manually every time you boot. Well, here is good news for Windows 8, 7 and Vista users because we have some patches here to make your 32-bit Windows support more than 4GB of memory.
Weirdly, Windows 20 can already address more than 4 GB of memory so why can’t we do that with Vista and newer operating systems?
The answer is: Microsoft doesn’t want that and it’s all just a licensing matter.
