Totally nothing to do with BOINC (for now), but just in case you're living under a rock, Microsoft released Service Pack 1 for Windows 7 last night.

You can go sit through the auto-update --which apparently takes 30 minutes or more-- or download the installation files by hand.

Be aware that this is quite a hefty download.
For 64bit the total download tallies at 3,407MB .. Isn't that a new Windows? ;-)
For 32bit the total download tallies at 3,116.2MB

I hope you have a speedy connection. When you do install, best keep BOINC turned off, or suspended through the whole ordeal.

I've downloaded all... now will sit on it for a couple of days, checking around that this thing doesn't cause instant Blue Screen of Death on people. :)

I guess the upper limit (while auto-updating) might indeed apply on fresh systems with no updates applied yet. IIRC that the lower limit for up-to-date systems was somewhere around 70 MB.
