Instructions for removing LSE on Lenovo computers

Bloatware are applications that are added to the device that the device manufacturer has included with the operating system. To remove unwanted pre-installed programs, many tech-savvy users often "clean" by reinstalling Windows after purchasing a computer.

However, for some Lenovo laptops and computers, you cannot remove the preinstalled programs by the above method. Ars Technica and Y Combinator discussion forums have accused Lenovo of installing unwanted rootkit software and cannot be removed on fixed Lenovo laptops and computer systems.

Lenovo representatives did not acknowledge or deny the presence of this software.

One of the most popular Chinese computer manufacturers "Lenovo" has been caught again using a hidden Windows feature to install unwanted rootkit software and cannot be removed on a fixed Lenovo laptop and Computer systems sold. This feature is called "Lenovo Service Engine" (LSE) - a piece of code that attaches the firmware on the computer's motherboard.

Lenovo representatives did not acknowledge or deny the presence of this software. Instead, they instruct users to update BIOS software on Lenovo computers to "Lenovo Service Engine" resolution .

LSE installs a software program called OneKey Optimizer (OKO) available on many Lenovo laptops.

OneKey Optimizer belongs to the "crapware" category. However, the only weakness is that both LSE and OKO are not safe.

Security researcher Roel Schouwenberg reports a number of security issues, including buffer overflows and unsafe network connections, to Lenovo and Microsoft causing Lenovo to stop installing LSE on its new systems built. The company has also provided firmware updates for laptops that have vulnerabilities and guidelines issued to disable options on affected machines and clean up LSE files.

Lenovo has released the LSE Windows Disabler Tool , you can refer to the instructions on how to install the software in the article below.
