Windows 7 Service Pack 1 (SP1), or KB976932, was confirmed as being pre-released to OEM manufacturers on February 9, 2011. The build had leaked to the Internet around January 14th. The official Windows Team Blog confirmed authenticity of build 1850 as the final RTM ("release to manufacturer") bits after much delay, debate, and discussion across the Internet. The release to manufacturer build contains the final bits which will ultimately be sent to MSDN customers, TechNet subscribers, Volume License Holders, and the general public. Before that, it is sent to OEMs. ("original equipment manufacturers").

Windows Server 2008 R2 SP1 and Windows 7 SP1 was released to manufacturers ("RTM") on February 9, 2011.

Microsoft has confirmed the RTM build number is 7601.17514.win7sp1_rtm.101119-1850 and we now have the highest level of certainty that these files are Windows 7 Service Pack 1 "Release to Manufacturer" (RTM), as we previously announced on January 14th. Microsoft TechNet Russia initially identified this build as the release to manufacturer version on January 14, 2011, but issued a warning that it had not yet been released to OEM partners.

Although the files have already leaked, we now have dates for the official release timetable:

TechNet/MSDN/Volume Licenses: February 16, 2011
Official Public Availability: February 22, 2011

The 32-bit and 64-bit versions are compatible with all languages. The 64-bit version also includes the Windows Server 2008 R2 Service Pack 1 RTM. Here is the following information:

We recommend that you:

  • Download any files at your own risk. We are not responsible for lost data or damage.
  • Observe best practices, including backing up your data prior to the installation of any operating system updates or modifications.
  • We, again, strongly recommend that you thoroughly backup your system prior to the installation of any operating system update.
These files have been digitally signed by Microsoft, preventing unauthorized tampering or modification at the time of signing. The digital certificates have not been altered or tampered with.

The files have been tested on various types of hardware, without problem or difficulty. This does not guarantee that Service Pack 1 will work for you.

Temporarily disable your anti-virus, save all of your work, and turn off all programs before running the installer. This will improve the likelihood of a proper installation. Follow all on-screen instructions.

One the most prominent features of Service Pack 1 is a new feature known as RemoteFX, more information on RemoteFX here. Service Pack 1 is completely compatible with the recent February Patch Tuesday updates.

How To Reduce Disk Space by Removing the Uninstall Files
Once Service Pack 1 is installed you may opt to remove old information regarding old hot fixes and the SP1 un-installation tool as well. Note that if you perform this step you can NEVER remove SP1! This is NOT recommended. On most systems you should expect between 500MB and 1.5GB of space recovered by running this program. To run you must launch a command prompt with Administrator privileges, then execute the following command:

dism /online /cleanup-image /spsuperseded

This command will take between 5 and 15 minutes to complete, when completed you will now have SP1 fully integrated with no un-installation option. Enjoy the reclaimed disk space!

Blocking SP1 from automatically installing
Prior to any installation, if you find that you wish to block the installation of SP1 automatically via Windows Update, please see the Link Removed. This will block the Service Pack from installing "valid for 12 months following general availability of the Service Pack".

How To Integrate or Slipstream Windows 7 Service Pack 1 (SP1) Into Installation DVD, ISO
To create an ISO or new DVD that includes Service Pack 1 as a slipstreamed (seamless) installation you can follow the tutorial here, please note that this tutorial is not an "official" method for creating a bootable SP1 installation media... however users have reported that this method works.

I just finished installing and everything appears to work OK. A few things actually seem to load faster than before.

I just installed it in my wife's computer via Windows update. It seemed to work just right. I'm sure she'll let me know if there's anything wrong.

I noticed a slight speed increase when I installed the leaked version on mine.

Something I noticed early on (last month when I installed the leaked files).
I run a tool at boot called Bootracer that reports my time to boot to a functional desktop.
Before installing the SP I could depend on an average boot time of about 35 seconds.
For several boot after installing the files boot time stretched to up to a minute before finally settling down to
around 35 seconds again.
I suspect that the SP somehow messed with the prefetch files and it took awhile for Windows to readjust.

There's nothing in SP1 to cause any noticeable performance gains. So it is likely something else was corrected during the reboots, or other updates. In fact...

Actually, it resets it so the first couple boots and user sessions could result in slower boot times for Windows and slower load times for your regular programs until the prefetch is recached again.

But did you? I did, started my stopwatch and that thing is really off from actual time.

Thats the one, it runs every boot.
My average is around 35 seconds to desktop.
I measured 43 seconds average with stopwatch.
These numbers are vastly improved over my XP-SP3 results on the same machine.
XP took almost 2 minutes to boot with the same startup items both bootime and delayed.

I have several tray items that are delayed until after my desktop is up and running, items not needed by windows but I find valuable, like CPU and HDD temp monitors and a utility that reminds me of my relatives birthday.
I use a tool called Startup Delayer for that.

When Bootracer reports my desktop is fully functional I can use it with no problem even when the other delayed startup items are loading.

@Digerati
You are right, I don't see any improvement in boot times after the SP install.
Thanks for the verification of the prefetch being reset.
That explains the slower boot times for the first few boots.
I also used to see slower boot times for several boots after using Win 7's builtin defrag utility.
I guess for the same reason.
I now use the free Auslocic defrag and it doesn't impact boot times.

Once you settle into a routine, it will optimize.

Also, note that boot times are not an automatic indication of performance. As long as there are no problems during boot, the performance once fully booted is what matters. With today's computers having lots of memory, and with programs in memory but not active using 0% CPU resources, starting the programs you regularly use when Windows starts is actually a time saver in the long run.

You're probably right there but I think I'll leave things as they are.
@Veegertx, thanks for reminding me.
The Bootracer site shows a version 3.1 I'm using version 2.3, time for an update.

It is important to take notice if suddenly boot times change, but trying to eke out every last second may result in you having to wait longer for other things to happen as they have nothing pre-loaded to speed that process up.

Actually the only tray items that aren't delayed are my A\V, power management icon, sound control and the stock Win 7 non-animated network indicator.
The delay items are DreamBreed Birthday reminder, process explorer, Virtual clone drive, Network-Activity- indicator, Notebook Hardware Control and CoreTemp.
NHC and CoreTemp are realtime monitoring apps.
Network-Activity-Indicator is an animated tray item like the old Vista and XP one.
The birthday reminder alerts me of upcoming birthdays 10 days in advance.
Virtual Clone Drive simply starts the VCD daemon.
Process Explorer is a Task Manager on steroids with a tray item.

I also run a shortcut to "C:\Windows\System32\w32tm.exe"/hide ""/resync"" ""/nowait""
to force Windows to update my system time at each boot since Windows doesn't seem to want to
consistently do it on it's own.

I use a tool called Winx32 to create a script that is then run 30 seconds after my desktop is fully functional.
Startup Delayer provides the delay.

None of these delayed apps are vital, they are just items I value in my system tray.
In total I have 10 items in my tray.

In this case there were no new features. It was mainly a roll up of critical updates. I think there was some change to memory management.

Not exactly true. If you read back through this thread, you will see the new features added - though admittedly, they are not important for most people.

I´ve read in other forums that SP1 is a compilation of all hotfixes uptodate and is not so necessary to install besides causes some troubles. I didn´t install at all for in case. Thanks anyway. Regards.

Most of what you said is true however there are a few items that are not in hot fixes, Yes some machines have had problems but that is very small percentage. If you are scared because of this small percentage and won't install,why would you do any updates? Some small percentage of users have problems with monthly hotfixes. Just make a backup prior to installing SP1. I also belive SP1 allows for removal in program features in case it does not work for you.

Only a tiny few had problems updating and of those tiny few, the vast majority were easily corrected. Bottom line is there is no good reason to not stay current.
