126 If Something Goes Wrong
The Windows® operating system is not working
Enable Safe Mode
Starts Windows® with a minimal set of drivers and services. If
the computer starts and runs in Safe Mode, you will know the
Operating System is most likely working properly and that you
should look to third-party applications or drivers for the source
of your problem.
Disable driver signature enforcement
Allows drivers containing improper signatures to be installed
Disable early-launch anti-malware protection
Allows drivers to initialize without being measured by the
Anti-malware driver
Disable automatic restart on system failure
Prevents Windows® from automatically restarting if an error
causes it to fail. Choose this option only if Windows® is stuck
in a loop where it fails, attempts to restart, and fails again
repeatedly.
Internet problems

My Internet connection is very slow.

Many factors contribute to the speed with which you can surf the
Internet. They include: network speed, network conditions, time of
day (when everyone else is surfing, your access can be slow) and
popularity of the sites you are trying to access. If accessing a
particular site is very slow, try later.

My browser cannot find the URL address I typed in.

Make sure you separated the domain names of the address with the
forward slash (/). Check the spelling of each name and the syntax of
the address carefully. A single incorrect letter or missed character
will make it impossible for your browser to locate the site.

My browser cannot find a site I bookmarked.

The World Wide Web is constantly changing. A site you
bookmarked yesterday may not be available today or its server may
be down for temporary repair. Try again later.
