Notice any difference in Windows 7 Service Package 1

Windows 7 Service Pack 1's most significant improvements just contain a hand full of minor releases. If you have been keeping up with the weekly Windows updates, then SP1 should be a simple / non-issue upgrade.

In short, this service pack adds surprisingly little to Windows 7.
In this case "SP" stands for "Slim Pickings."

On top of that it appears that the code for SP1 was frozen as far back as mid-to-late-November. The files are digitally signed 11/22/2010. The official build identification string, 7601.17514.win7sp1_rtm.101119-1850, refers to November 19 ("101119"). The installer executable is dated November 23. That's a long, long time ago.

This is a list of the Windows 7 SP1 fixes:

1) Higher-definition connections with Remote Desktop: If you use Remote Desktop (I prefer the third-party service LogMeIn), installing SP1 on both PCs sets up high-definition connection via a new technology Microsoft calls RemoteFX.

RemoteFX is based on virtualization technology Microsoft acquired two years ago when it bought Calista Technologies, RemoteFX makes it possible for full graphics to show through on remote sessions. Someday, we're promised, you'll be able to use RemoteFX with your phone. I'm not holding my breath — I'm not even sure I'd want it, but only time will tell.

2) More Windows Live ID support: A technology Microsoft calls "Microsoft Federation Gateway" will give SP1-enhanced PCs improved Windows Live ID authentication to non-Microsoft sites, using a long-established Web services protocol known as the WS-Federation Passive Requestor Profile. I thought Win7 already had WS-Federation profiles (detailed in an MSDN article: http://msdn.microsoft.com/en-us/library/ms996532.aspx) nailed, but apparently some fix is necessary.

3) An HDMI patch: I have no idea why MS emphasizes this as one of the noteworthy changes in Win7 SP1. It's a bug fix to keep HDMI working when a PC is rebooted.

4) An XML Paper Specification fix: The 10 of you who actually use XPS instead of PDF will be pleased that SP1 fixes a print bug affecting mixed portrait and landscape documents.

5) Even more-obscure fixes: These include restoring previous folders at sign-in, IKEv2 protocol improvements (used in VPN connections), and a hotfix rollup from November (KB 982018: http://support.microsoft.com/kb/982018) for Advanced Format disks. Little stuff.

Not really,

What's said to be new? I know there is meant to be something for the server OS, but nothing really other than bugfixes for 7

Using it now from MSDN, its just a bunch of bug fixes clunked together like usual SP's. Its really there to help you update a system faster or install from a more recent updated system, to prevent the well known 1,000 updates from hell Windows XP issue.

There is really no differences from the original to running SP1 except the RemoteFX feature and the Dynamic Memory. I have seen no performance changes and there really is not upgrade. The RemoteFX feature is nice. And I have seen no change with the Dynamic Memory management system.
