Which update need to make Windows 7 wSP1 Enterprise 64bit to boot faster?

What it means "Faster"? How fast or slowly it currently starts up?
What is Your computer, most important is the CPU work frequency and also very important is which hard drive is in use.
There is such a level or speed for every pc, which isn't possible make to start up faster in any way.
If your computer is more or less okay, its startup time is normally always quicker than 90 seconds, if is HDD, and faster then 60 seconds when is the SSD.
Also, if the CPU frequency is higher, it start faster. For example, if everything else is the same but only in one pc is freq = 1.666 GHz and in another the freq = 2.1 GHz, then starts up about 3 times faster.
Also is important, if You have HDD, that it is correctly defragmented. SSD don't need to defragment, most of all, it is not recommended to defragment never.
RAM is not very important, it is enough, what You have, because I think you know that in the Windows is a 4GB RAM usage limit. If you want to use more, it is not sufficient just to add RAM. It is necessary to activate the PAE. (A Technique Called also Physical Address Extension, or PAE)
Good luck to You.

 

Install Windows 10

 

Discussion was about windows 7 not 10 and I would say kaljukass gave good reply

 

Thanks! Windows 8 or 8.1 boots up faster only, if is enabled so called "fast booting function" or the hibernation and You use it. If You use normal booting, then isn't any difference.
If you have a 500GB HDD, I recommend you split it into two, and you get a little bit (but little) faster startup. But in spite of this, split the HDD at least to two partition.
Recommended, first or the bootable about 160-200 GB and then the other will be about 260-300 GB. (if You have 500GB HDD disk, then can be use about 465GB )
And why not install Windows 10?

I'm sorry, but you still have not said what is it a slow start-up and how it was or is measured.

 

16 seconds slow? Many systems are slower.

 

You say, 16 seconds? It is not possible, in any case is not possible, if You have Windows 7 and HDD. Somewhere something is very deeply wrong.

 

16 seconds? No matter what you do, your marginal gain is going to be slight if even noticeable. If any of my machines went from dead cold to fully loaded and running in 16 seconds, I'd think I was in the Twilight Zone.

I'd like to see a real time video of that boot process as I've never seen one boot that fast or even close to it. And as I've read on more than one forum, "If you don't have pictures, it didn't happen".

 

As was already said, the perceived faster Boot by Win 8.1 is probably because it uses a "fast booting function". You can achieve essentially the same fast Boot in Win 7 by enabling hibernation and using it instead of a "cold start". That's all the "fast booting function" is. There is no update or convenience rollup that makes Windows 7 boot faster that I am aware of.

Cheers and Regards
