In a word - yes.
Some people make multiple images "just in case". They might make one immediately after installing the operating system and all updates and verifying that things work the way they should. Then make a second one after installing other programs. It really depends on what works for each person's needs.
The Windows 7 imaging tool (Start > Control Panel > Backup and Restore > Create system image) is a basic tool without too much flexibility. Some people have reported problems, others like myself have used it many times without any issues. Other free products you might consider are Macrium
, and EaseUS Todo
. You could do an initial system image using Windows 7 (very straight-forward operation) along with the companion system repair disk (in case you machine ever fails to boot) and then play around with the other imaging tools.
