The first [full] paragraph says, “Once you get past Windows Defender, Installation is a snap.", but “Installation” doesn’t really need to be capitalized. The next sentence says “Chose the “Install for me only” option”…”, but probably means to says “Choose the…”

Additionally, the repetition of “and then” feels excessive:
“Once you get past Windows Defender, Installation is a snap. Chose the “Install for me only” option and then select “I accept the License” (after reading it carefully, of course) and then click Next.”
could simply say:
“Once you get past Windows Defender, installation is a snap. Choose the “Install for me only” option, select “I accept the License” (after reading it carefully, of course), then click Next.”
