Windows 7 64 Bit with SP3 installation needed

Hello everyone
Does anyone have or know where I can download Win7 SP3 install for 64 and 32 bit system. I need an installation pendrive to create.
Thank you in advance for your help.
best regards

You can download http://basewin.pl/ from here, but it was not officially SP3 for Windows 7.

I just need to install Win7 pro with SP3.
I have several Lenovo laptops that I use for car programming and I have some problems all the time.
I got the information that it is best to Install Win7 with SP3.

Here is kind of SP2 -

officially, not even SP2, not to mention SP3.

So the kb3125574 update is SP2? Can it be combined with the installation on a USB flash drive?

I'm sorry but I asked and it was about Win7 pro with SP1.

So is it better to install this kb3125574 update as well?
And is the WiN7 pro installation with the integrated SP1?

In fact, there are several types of WiN7 pro
64-bit versions:

Do you know how they differ?

The SP1 is the only official SP and it was released at a later date.
There have been different editions of Win 7

Pick the middle one.

SP3 was official for Windows XP.

Thanks for the help.
And will you tell me what this update is and whether it should be installed?
Update for Windows 7 (KB3125574)

When reinstalling W7 it is better to install kb3125574 right away, there will be fewer patches later.
