J'ai installé Windows 7 on an old laptop yesterday evening, so that I could experiment avec Win32 API programming. I started it updating about 5 hours ago. It téléchargé the mises à jour in 30 minutes or so, but as of right maintenant it is encore l'installation them, and seulement 58% complete.
Pourquoi this taking so long, and what puis-je do to hasten it?
The laptop is an HP Pavilion dv6701us, avec 2 GB of RAM, a 120 GB SATA hard disk, and a dual core Pentium D CPU, for what c'est worth.
Mise à jour (July 18 2015):
I've maintenant observed this behavior on every Windows 7 machine in my household, 32 and 64 bit alike. Il semble que almost invariant avec respect to RAM, CPU speed and number of cores, even SSD vs. HDD. All Windows 7 systems J'ai vu updating, take over 8 hours to installer 200 mises à jour.
Is there anyone for whom Windows Mise à jour is not spectacularly lent?

I n'était pas entirely satisfied avec the answer below - can Microsoft really be shipping quelque chose that broken? - so I decided to have a go at it avec Sysinternals procmon. Ceci est what I see, over and over again, while Windows Mise à jour hangs and ne even start downloading stuff:

That WindowsUpdate clé ne exist. Could be c'est supposed to be nonexistent; but I strongly suspect otherwise, seeing as it is accessed over and over and over again by the updater's service host processus, in a seemingly endless loop. The question in that case, though, would be: what entries/valeurs should it contain?
Google/Bing jusqu'à présent n'a pas turned up anything, but I'm going to keep looking on this.
Mise à jour 2 (September 14 2015):
J'ai essayé the hotfix from ici:
https://support.microsoft.com/en-us/kb/2700567
It claimed to fix some things, including quelque chose about the mise à jour service registration being manquant or corrupt(!). Bizarre. C'est un fresh Windows 7 SP1 installer.
... Cependant, Windows Mise à jour is encore just as slooooooooow as avant, chugging away at 50% of disponible CPU power while appearing for all the world to be stuck in an endless loop.
Je viens de ne understand this. Windows has 90% du desktop utilisateur base, it cannot possibly be this awful par défaut... I will keep investigating.
