Instead of approx. 7 minutes per task, it now takes about 1 hour. Also, my laptop isn't running as hot anymore, although the CPU shows 100% usage. Any idea?

The WUs take varying lengths of time, they are not all the same. Your laptop running cooler is a good thing!

Until now, they where all finished within 15 minutes, without exception. Now it runs between 1h and 1h30. Can you confirm that you're seeing the same?
I have the impression it might be my laptop that's throttled the CPU.

It's my laptop... Suddenly it decides to throttle the CPU for some reason. Sometimes it's running at full speed, then it switches to 800MHz for a couple of minutes/hours. Any idea what this can be? Energy settings are still the same, both in Win7 as in the BIOS.

I have a Dell that does that if it's running a low load, but if you're running the CPU at 100% with Boinc then it must be the CPU overheating and throttling back to stop burning itself out.
Best bet, run a CPU temperature sensor programme and watch that and the CPU load at the same time. Laptops are notoriously bad with heat - I speak from experience!

Check your power plan in the Control Panel, Power Options, Plan settings. Do not choose the High Performance setting. Vacuum out the laptop vents too.

Found it! It was the power supply. My laptop didn't get enough power to and charge the battery and power my cooking CPU. As soon as I connected the new one, the fan started blowing and my WUs were finishing in 5 minutes again.
