Anyone found that before? You have a Windows Update that asks for a reboot. But, you do not reboot right away because you have 25 opened windows and projects and you need all that to remain as is. Then, you hope to reach the weekend, to reboot, and get a new start. However, the more you wait, the more your PC gets slow. This is the 3rd time I have observed that. Otherwise, I can work for weeks without a reboot and all is ok. But, when there is a pending reboot, it is doing that.

...and this is when you see the ad on TV "My Clean PC". Geez, this guy is scary! :)
