Lenovo promises Windows 10 devices will be adware and bloatware free

Says Superfish clean up will be finished for new OS' launch

Lenovo has promised to purge all adware and bloatware from its devices before the launch of Microsoft's next generation Windows 10 operating system.

Lenovo issued the promise following widespread concerns about its decision to install the notorious Superfish adware on a number of its consumer laptops.

"The events of last week reinforce the principle that customer experience, security and privacy must be our top priorities. With this in mind, we will significantly reduce preloaded applications," read the statement.

"We are starting immediately, and by the time we launch our Windows 10 products, our standard image will only include the operating system and related software, software required to make hardware work well, security software and Lenovo applications.

"This should eliminate what our industry calls ‘adware' and ‘bloatware'."

Controversy around Lenovo's use of Superfish erupted on the Lenovo forum earlier in February when several customers reported finding Superfish installed on their machines.

Superfish is adware that collects data such as web traffic information using fake, self-signed root certificates and then uses it to push adverts to the user.

The certificates are dangerous as they leave machines with Superfish installed vulnerable to man-in-the-middle cyber attacks.

As well as a public backlash the use of Superfish is believed to have prompted hackers in the Lizard Squad group to target Lenovo's website with a redirect attack.

The attack occurred on Wednesday and forced Lenovo.com to display a slideshow of images while playing Breaking Free from High School Musical.

Since the controversy broke Lenovo has teamed with McAfee and Microsoft to release Superfish removal tools.

The firm has also announced plans to be more transparent about what software it uses and to rethink its product design strategies.

"Lenovo will post information about all software we preload on our PCs that clearly explains what each application does," read the firm's statement.

"We will continuously solicit feedback from our user community and industry experts to ensure we have the right applications and best user experience."

Microsoft unveiled Windows 10 in October 2014. A technical preview of the operating system is available now. Microsoft is yet to give Windows 10 a firm release date, though it is expected to launch around Q3 this year.
