This is software (developed by Lenovo or other software vendors) installed and licensed at
factory for your convenience. The license for some preinstalled software may be for trial
versions. When the trial period expires, you may need to purchase a license if you want to
continue to use the software.
If a license agreement is displayed when you first start the software, read the agreement carefully. If
you don’t accept the terms of the agreement, do not use the software.
When I purchased my computer, it included a copy of Windows. How can I determine whether the
copy of Windows is preinstalled by Lenovo?
On the outside of the sales package of your computer, you should find a label containing
configuration information for your computer. Check the printed string next to OS. If it contains
Windows or WIN, the copy of Windows was preinstalled by Lenovo.
I uninstalled a preinstalled software, but there is no significant increase in the free drive space.
The copy of Windows running on your computer may be Compact-enabled. For computers with
Compact-enabled Windows, the majority of files needed for preinstalled software are installed on the
Recovery Partition and won’t be deleted through normal uninstallation.
