I've recently installed Windows 7 64 bit on my PC.
I've noticed now and again Windows Explorer seems to hang and I'm unable to expand directories etc. as the cursor just shows a timer (spinning circle).
If I close Windows Explorer and re-start it, then it only shows Favorites, Libraries and Homegroup!
Trying to reboot the PC also gives problems and it simply hangs when in this state and it is necessary for me to press the reset button.
Any idea what is going on? I really like Windows 7 but this is making it difficult and frustrating to use.
