Windows 7 SP1 RC leaks to the web

It's well known that Microsoft is prepping a service pack for Windows 7, and now it appears an RC version has leaked to the web. The current build weighs in at a hefty 353 MB and is currently making its rounds on your favorite torrent site. Microsoft is expected to release a SP1 build this week at PDC 2010 on October 28th. Just with any service pack, Windows 7 SP1 will contain all previous fixes and patches rolled up into one update, as well as bug and security fixes that are still currently being tested.

According to Wzor, the leaked Windows 7 service pack comes in at Build 6.1.7601.17105.100929-1730, which indicates that the release was blessed by Microsoft on September 29th, almost a month ago. This age could also indicate that there are possible revisions to the release that is currently circulating.  

Wzor has an incredible track record for these types of things, its probably safe to say that this is the real deal. However, as with any leak, install at your own risk as this is not an official release by Microsoft and depending on who you download it from, the file could have been altered.

Again, This is a Release Candidate software, install at your own risk!

Not long until the official release is it?

I also reinstall windows with the latest SP


Ill problably do this as well even though I formatted I believe less than a month ago.

looking forward to it. i really hope it'll fix a very annoying bug i have with my 7 explorer, everytime i added a new column (date created), after reboot few times, date created column disappears for no reason. very very annoying.

Could someone give me a good guide to slipstream Service Packs onto a Windows 7 ISO? I haven't found one really that satisfies

I do a lot of formatting for my friends and family and my bandwidth cap would really appreciate the skipping of a lot of updates.

You may need to use waik as there isnt really an option to slipstream

Just use this program: http://www.rt7lite.com

I used it yesterday to slipstream SP1 (don't ask where I got it hehe) into W7, loaded the ISO in VirtualBox and it installed perfectly.

How can a service pack be buggy? It's just updates isn't it? I don't understand.

Partially because there are simply so many, with different people needing different ones for different configs in different ways. Especially patches with pre-reqs, you can get buggy installs if the checks aren't there or can be defeated or accidently ignored.

Hope SP1 fixes aero minimize stutter, as well as this odd UPS bug I get - Windows shuts down on login screen (because it thinks my APC UPS is on battery?), I've had to pull out the USB connection since to stop this.

UPS issue sounds driver related, and your stutter issue may be as well, what is your GPU? (and GPU WEI score?)

No, anytime you minimize a window in Aero, even if you've got a Core i7 980X with 2 Gig video card, there is a tiny bit of "lag" in the animation that is shown during the minimizing process.

I don't have any lag when minimizing a windows with Aero enabled, and I only have midrange hardware. I agree with Sraf, it could be driver/hardware related.

Def. driver related. I've had this with the first versions of the OS along with my 7600GT AND GTX260. Bug went away with new driver updates (from microsoft update).

i dont see any lag in minimising either and i have a core i5 760 and a gtx 470 1280meg

So, what exactly will SP1 do? There's not much you can improve in the way of performance on Win7...

Its supposed to do nothing - bunch of patches and updated packed nicely into a single package

There's a couple of Windows Explorer quirks that could stand to be fixed. Mostly intermittent stuff. Either way it won't be an exciting update for the client side of things.

Remote desktop will get a lot smoother, along with HyperV updates for the server side and then mainly hotfixes not dished out via windows updates (but available from support) are what you'll see - the rest is whats already available via windows update - but made easilly deployable in one package you can slipstream

No, it's clearly the perfect OS!

So here we go.. the Piratebay anyway sure it wasn't accident, Microsoft leaked it like they leaked all the betas of Windows 7.

Uhhh. No. Microsoft doesn't leak anything. People within Microsoft do. It's not the official policy of the company to do that.

Are you sure? So, why Microsoft doesn't stop them?

Definitely not that easy to stop man... lol

If all builds were tagged it would be. Easy enough to see who leaked it and fired. Sure it did not stop it but stops that person from doing it again and scares anyone else from doing the same.

Could you please list these bugs.

Too late now. I forgot then. But I can remember they did not fix the refresh bug. Let's see now. Downloading...

If your going to state that final build of the release version of windows 7 is buggy you better back up that statement with the list of bugs. If not yo ureally should not be stating something like that.

I have problems with my desktop icons disappearing. I have to re-enable them after entering Windows sometimes. This happens on several Win7 installs I have, and on different versions. It's not every time though, and happen fairly infrequently. The refresh bug is another.

I usually correctly list all of the bugs I find. You don't have to tell me obvious good behavior.

The disappearing desktop icons one is a terribly misguided feature, for which there are workarounds:

The refresh one is certainly a bug that, unless MS is completely asleep at the wheel, they'll fix well before SP1. But it's been known for ages and nothing yet, so I have my doubts.

I hope they fixed many, many things from the previous buggy public build.


bugs WHAT bugs windows 7 has been a rock ! runs great no errors !

I really don't have any problems. Various different build versions on different hardware... Problems are very few and far between here. Not sure about this 'refresh bug' error either, never heard of it.

Refresh bug is once in which the desktop or explorer window does not refresh correctly when you do something that should cause it to refresh.

Example. Your viewing your desktop. Nothing is in the recycle bin. You delete a file from the desktop. After deleting the file it still appears to be on your desktop. And the recycle bin icon did not change. You refresh the desktop. Now the file vanishes and the recycle bin icon changes as expected. You now empty the recycle bin. Recycle bin icon does NOT change. Again you manually refresh the desktop and it changes as again expected.

So basically the desktop was not refreshing like it should be. I've had this issue many times, started back in WinXP beta days for me. Very very annoying!

Thankfully it does not last long normally. And a few seconds later it will refresh itself.

Also happens with explorer windows. Even more annoying!

By all accounts, isn't this thing a classic traditional Service Pack? Is there a reason to try out a suppose RC/Beta/whathaveyou build of it?

To be on the bleeding edge, that being said, you can expect to bleed a little.

jimmyfal said,
So, what is new? If I already do our updates, what would sp1 provide for me?

Lots more. The monthly security updates are nowhere near the # of fixes that go into SPs. SPs also contain dozens of other hotfixes created in between RTM and SP1 that weren't released to everyone via MS Update, but may have been available via support if you called in.
