Windows 7 Build 7601 this copy of windows is not genuine

I have had a Lenovo T420 for more than a year. Yesterday I was suddenly got the above error message. I called Lenovo. They said I would have to restore my computer to factory settings, which involves reloading everything on the computer--software, files,

etc. I am starting here first to see if there is another way. Here are the diagnostics results.Diagnostic Report (1.9.0027.0):-----------------------------------------Windows Validation Data--&gtValidation Code: 50Cached Online Validation Code: 0xc004c4a8Windows Product Key: *****-*****-MV8MH-98QJM-24367Windows Product Key Hash: wgci5Gdejx4esg7++zTOe3LWF+4=Windows Product ID: 55041-OEM-8992671-00437Windows Product ID Type: 2Windows License Type: OEM SLPWindows OS version: 6.1.7601.2.00010100.1.0.048ID: {213B58D1-7968-4F03-8557-B27E99EE4C2C}(3)Is Admin: YesTestCab: 0x0LegitcheckControl ActiveX: N/A, hr = 0x80070002Signed By: N/A, hr = 0x80070002Product Name: Windows 7 ProfessionalArchitecture: 0x00000009Build lab: 7601.win7sp1_gdr.120830-0333TTS Error: T:20130129193057976-Validation Diagnostic: Resolution Status: N/AVista WgaER Data--&gtThreatID(s): N/A, hr = 0x80070002Version: N/A, hr = 0x80070002Windows XP Notifications Data--&gtCached Result: N/A, hr = 0x80070002File Exists: NoVersion: N/A, hr = 0x80070002WgaTray.exe Signed By: N/A, hr = 0x80070002WgaLogon.dll Signed By: N/A, hr = 0x80070002OGA Notifications Data--&gtCached Result: N/A, hr = 0x80070002Version: N/A, hr = 0x80070002OGAExec.exe Signed By: N/A, hr = 0x80070002OGAAddin.dll Signed By: N/A, hr = 0x80070002OGA Data--&gtOffice Status: 109 N/AOGA Version: N/A, 0x80070002Signed By: N/A, hr = 0x80070002Office Diagnostics: 025D1FF3-364-80041010_025D1FF3-229-80041010_025D1FF3-230-1_025D1FF3-517-80040154_025D1FF3-237-80040154_025D1FF3-238-2_025D1FF3-244-80070002_025D1FF3-258-3Browser Data--&gtProxy settings: N/AUser Agent: Mozilla/4.0 (compatible MSIE 8.0 Win32)Default Browser: C:Program Files (x86)Mozilla Firefoxfirefox.exeDownload signed ActiveX controls: PromptDownload unsigned ActiveX controls: DisabledRun ActiveX controls and plug-ins: AllowedInitialize and script ActiveX controls not marked as safe: DisabledAllow scripting of Internet Explorer Webbrowser control: DisabledActive scripting: AllowedScript ActiveX controls marked as safe for scripting: AllowedFile Scan Data--&gtOther data--&gtOffice Details: &ltGenuineResults&gt&ltMachineData&gt&ltUGUID&gt{213B58D1-7968-4F03-8557-B27E99EE4C2C}&lt/UGUID&gt&ltVersion&gt1.9.0027.0&lt/Version&gt&ltOS&gt6.1.7601.2.00010100.1.0.048&lt/OS&gt&ltArchitecture&gtx64&lt/Architecture&gt&ltPKey&gt*****-*****-*****-*****-24367&lt/PKey&gt&ltPID&gt55041-OEM-8992671-00437&lt/PID&gt&ltPIDType&gt2&lt/PIDType&gt&ltSID&gtS-1-5-21-3484988888-2535306700-3744271095&lt/SID&gt&ltSYSTEM&gt&ltManufacturer&gtLENOVO&lt/Manufacturer&gt&ltModel&gt4177CTO&lt/Model&gt&lt/SYSTEM&gt&ltBIOS&gt&ltManufacturer&gtLENOVO&lt/Manufacturer&gt&ltVersion&gt83ET61WW
