Adds features and settings that don't appear from regular updates.

Summary
Old computer, older driver bHind kb. WARNING: i dislike M$not with almost a passion! Their ability/agility to shift servers is nearly as good as ability to put out pricey, bug laden, bloated very thinly veiled crapware.

Pros
works great
Cons
none that Im aware
Summary
Works just fine.I don't know why anyone had any issue.Maybe they're browser canceled the download before it could start ? Ive been having that issue with Mozilla v .3.16.3 and I wish they would fix this soon.Anyways just go to the download section under tools so you can see the download then hit retry.Worked for me .You also want to make sure your security settings aren't blocking downloading the file and to allow it to when you see the warning message.
JUNK. WILL NOT DOWN LOAD. KEEPS JUMPING IN TO DOWN LOAD

WHEN SHUTTING DOWN, IT WILL DELAY SHUT DOWN UNTILL IT INSTALLS, WHICH IT NEVER DOES. A WASTE OF MY TIME TO MEES WITH. BUT I CAN'T GET RID OF IT. KEEPS TRYING. I DON'T KNOW IF IT'S ANY GOOD ORNOT. SO FAR IT'S JUNK.
