Steam Folder Migration: USB 3.0 external storage drive, to internal SSD

We recently complete updating storage on Dawn's laptop, adding additional capacity and modifying partition sizes.

Today, we moved the Steam folder, from a Samsung T1 Portable 250GB USB 3.0 External SSD, to her newly expanded laptop internal SSD, loosely following the instructions on the Steam web site:

• Exit the Steam client application
• Browse to the Steam installation folder for the Steam installation you would like to move (D:\Steam, for us)
• Copy the folder to the new location; for example: C:\Program Files\Steam
• Delete all of the files and folders, in C:\Program Files\Steam, except the SteamApps folder and Steam.exe
• Rename D:\Steam to D:\SteamBackup
• For the first time only, launch Steam via "Run as Administrator", then log into your account
• Running as non-Administrator, Steam produced an error which said (paraphrasing): "Could not connect; please connect to a network and try again
• Running as Administrator did not produce the error
• Verify integrity of game cache(s):
• From the Library section, right-click on the game and select Properties from the menu
• Select the Local files tab and click the Verify integrity of game cache... button
• Steam will verify the game's files - this process may take several minutes
• Once the process is completed, the Check Window will automatically exit
• Manually update the Start Menu shortcut, for Steam: right-click on the icon, select Properties, then change the location the shortcut points to, so it points to the new folder (for us, we changed it from D:\Steam\Steam.exe, to C:\Program Files\Steam\Steam.exe)

Done. 

NOTES

• After you have some confidence that Steam works as expected, you can either keep D:\Steam as a backup, or delete it
• OK to start Steam as non-administrator, for all future uses...that first time, above, Steam needs administrator rights to repair itself

Previously, previously, previously.
