Windows 7: Why did My laptop lag when I am installing 1 window update?

Why did My laptop lag when I am installing 1 window update?

My laptop has 8GB of RAM and Intel i7 quad 2630m. I had mozilla firefox + google chrome opened with 3-6 tabs while playing youtube video but when I was installing this 1 windows update my laptop lagged until it the update was nearly completed.

I don't think I should be lagging but my question is when installing windows update is it normal to lag and does it use the CPU or Hard drive?

Which Update??

Some updates do a lot of work - and some do very little.
.NET updates can be very intensive, and require re-optimisation of the framework, which may make the system lag for a few minutes.

Koolman511 if I read your post correctly, you had:

while you were doing this Windows update?

You can certainly use your machine as you see fit, and it does seem like a powerful one, but it would be prudent to close all other programs, and files when updating Windows system files. especially .net .

Maybe Noel could clarify, it just seems like your only playing with fire if your updating that way.

Having other programs running while doing updates isn't best practice, but Windows can almost always work around it. If necessary it will put the updates into a 'Pending' folder, and then force a reboot to complete the installation.

Thanks Noel!

EDIT:

I never had luck that way even back to the 3.1 days, so, I install in groups; .net, security, general, etc. .
Does take a little longer, but if it makes my machine happy, I'm happy.

I'm with you, when installing a bunch of updates - I always leave the .NET ones until last, and install them a couple at a time (oldest first).
However, if the machine is kept up-to-date, I simply let Windows deal with it unless I know there are likely to be problems. MS has got a LOT better at updates over the years - I remember Win95 and win98/ME ones being a real PITA!
