Microsoft Windows 7 (Home Premium)

Pros: Taskbar is functional, I like the "pin" feature. Will run for weeks without reboot.

Cons: I'm still getting used tp the new look of Windows Explorer. It just takes a little longer to find a file that a new program saved, It would be nice if Media Player and Movie Maker opened .mov files, video camera saves files in this format.

Summary: Computer is a Compaq CQ-210US laptop, originally with Vista Home Premium, SP2, 2 GB ram, 250 GB HD. I did a complete file backup, per instructions, in case. HP furnished an upgrade kit, including 2 disks. The first was a driver check-and-upgrade disk, to prepare for the switchover. The second was a Microsoft Win7 disk. I selected the "upgrade" option.

The upgrade had only one hitch, because the instructions did not specify when to remove the
Win7 installation disk, so the process started over on reboot. Nevertheless, the upgrade completed flawlessly, and resulted in a fully functional OS, with NO loos of files or associations. I never needed the backup.

All in all, I am impressed. I have been using Microsoft OS's since DOS 2.2, and believe MS got it right. Upgrade took about 4 hours, with startover included.
