Now coming to my update:
The download got completed today, and i installed it right away. I kept all my Files and Settings. The update took about 1 hour.
After the update the PC rebooted and windows 10 was right there ready to use. But something looked missing ???
The icons looked big, the colour was pale and lacked quality. The animation while opening apps and switching between them was laggy. I then decided to look at the drivers, and to my surprise the drivers of my HP PC were not there. That explains the issue in Wifi, colors and the icons laggs. I searched for win 10 drivers for my HP laptop online and there was no win 10 drivers available for that product, latest being for win 7. I taught i made a mistake by upgrading.
Then i decided to check for win 10 updates, and to my surprise it made me available all the missing drivers for win 10. I downloaded it and it was awesome feel to get back all the drivers.
All the issues like Wifi, Colors, Laggs, icon issue and other issues were fixed and resolved. Windows 10 is the best. Its Super fast, and its just awesome.
Thank you Microsoft Windows
