Problem: Ability to share Desktop PC internet connection to a laptop or your iphone/htc wirelessly.
Solution: First of all you need to purchase an USB Wireless Adaptor (since there is no wireless in a pc by default), in order to share your connection wirelessly (your laptop is a must have wireless already). I purchased it from eBay for 6$.
1.Open Network and Sharing Center
2.Under “Change your network settings” choose:
3.Next choose → Set up a wireless ad hoc network
4.Give your network a name, a password (example on picture) and save this network
