Windows Update Failure

[mikedann]

Windows files and some programs will not update. I believe that TrustedInstaller.exe is missing frommy computer. I have run Wise PC 1stAid, and some updates now work, but not all.

Operating system:Windows 7 Home Premium (64 bit) Service Pack 1

Available physical memory: 3971 MB
CPU: Intel® Core i3-3110M CPU @ 2.40GHz

Hi mikedann.

 

Did you try the Windows Update Troubleshooter (win7 onwards) ??

If not, try it first.

Otherwise, try the following:

Download and run System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [October 2014]

From an elevated command prompt, launch (Windows installation cd could be necessary):

sfc /scannow

Wait till it finishes (15-50 minutes).

If the final result is equal to Windows Resource Protection did not find any integrity violations or equal to Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log, launch this command:

copy %SYSTEMROOT%\Logs\CBS\CheckSUR.log %userprofile%\desktop\CheckSUR.txt

After it, you should find checkSUR.txt on your desktop: post it here.

Instead if the final result of the SFC TOOL is equal to Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log, launch both the previous command in the code above AND also this command:

copy %SYSTEMROOT%\logs\cbs\cbs.log %userprofile%\desktop\cbs.txt && findstr /c:"[SR]" %userprofile%\desktop\cbs.txt > %userprofile%\desktop\SR.txt

After those two commands, you should find three files on your desktop: checkSUR.txt, cbs.txt and SR.txt: post here the checkSUR.txt and the sr.txt.

If the last command won't work, try these (one by one):

copy %SYSTEMROOT%\logs\cbs\cbs.log %userprofile%\desktop\cbs.txt
findstr /c:"[SR]" %userprofile%\desktop\cbs.txt > %userprofile%\desktop\SR.txt
