We purchased this for its supposed environmental toughness to be used in a dirty factory. When we booted it up, Windows had already been activated. No clue if they registered it under their name or not.Per some of the other reviews, I decided to scan it with a few different virus detectors. It found 10 items that were concerning. These keys and files do NOT come with Windows, so they had to have been added by whoever decided to activate this license. Side note, reputable companies typically send you the key for you to activate Windows.I setup a new admin account, nuked the original admin account, updated Windows, and did several more sweeps with the antivirus software.I don't see any particular issue with this computer, physically, but please, please, please be wary of these machines. ALWAYS scan any machine that comes pre-activated.Registry Key: 4PUP.Optional.Ludashi, HKU\S-1-5-21-872650850-1196156968-1511338401-1001\SOFTWARE\LUDASHI, Quarantined, 1305, 340603, 1.0.30986, , ame, , ,Adware.ChinAd, HKLM\SOFTWARE\WOW6432NODE\QiLu Inc., Quarantined, 549, 375034, 1.0.30986, , ame, , ,PUP.Optional.Ludashi, HKLM\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\APP PATHS\ComputerZ_CN.exe, Quarantined, 1305, 340607, 1.0.30986, , ame, , ,PUP.Optional.Ludashi, HKLM\SOFTWARE\WOW6432NODE\MICROSOFT\WINDOWS\CURRENTVERSION\APP PATHS\ComputerZ_CN.exe, Quarantined, 1305, 340607, 1.0.30986, , ame, , ,Registry Value: 3PUP.Optional.Ludashi, HKU\S-1-5-21-872650850-1196156968-1511338401-1001\SOFTWARE\LUDASHI|360LOCK, Quarantined, 1305, 340603, 1.0.30986, , ame, , ,PUP.Optional.Ludashi, HKLM\SYSTEM\CURRENTCONTROLSET\SERVICES\SHAREDACCESS\PARAMETERS\FIREWALLPOLICY\FIREWALLRULES|{6D531C8A-2F8D-42CC-B5B9-0E342A76CCFE}, Quarantined, 1305, 393617, 1.0.30986, , ame, , ,PUP.Optional.Ludashi, HKLM\SYSTEM\CURRENTCONTROLSET\SERVICES\SHAREDACCESS\PARAMETERS\FIREWALLPOLICY\FIREWALLRULES|{83EFCBE0-F369-4C06-A17C-A6EFCB4F2AFA}, Quarantined, 1305, 393617, 1.0.30986, , ame, , ,Registry Data: 1PUP.Optional.Hao360.ShrtCln, HKU\S-1-5-21-872650850-1196156968-1511338401-1001\SOFTWARE\MICROSOFT\INTERNET EXPLORER\MAIN|START PAGE, Replaced, 4941, 349832, 1.0.30986, , ame, , ,Folder: 1PUP.Optional.LockHomepage, C:\USERS\KINGDEL\APPDATA\ROAMING\LOCKHOMEPAGE, Quarantined, 1319, 316526, 1.0.30986, , ame, , ,File: 1PUP.Optional.LockHomepage, C:\Users\Kingdel\AppData\Roaming\lockhomepage\LockHomePage.ini, Quarantined, 1319, 316526, , , , , 45832085E1E56042CE56E815DAE66FC9, 82EBA1CDFD6967C1A913AD418B0EFC3B9667C1FF4766387751D5EB3B75A78DBD
