This is a interesting and describing forum post about Lenovo putting some Lenovo CrapWare in the UEFI BIOS which Windows will execute upon login (right before actually): http://arstechnica.com/civis/viewtopic.php?p=29497693&sid=ddf3e32512932172454de515091db014 Lenovo has issued a fix: https://support.lenovo.com/us/en/product_security/lse_bios_notebook and an article: http://news.lenovo.com/article_display.cfm?article_id=2013
Links, commands and settings I someday probably won't find again
