I have seen at several client sites an issue in which the SCCM Client significantly slows down the machine. Looking deeper into the problem it seems to be with the Windows Update scans.
You will notice performance loss and device slowdown as it has issues with its update scans. In this case it was the System Center Configuration Manager 2012 R2 Client and the 1511 Client.
Found the client to be having issues in the WUAHandler.log ‘Failed to end search job. Error = 0x8024001e’
Created SCCM Package to push updates:
WindowsUpdateAgent-7.6 (or newer this was the one at the time)
Program: (Batch File)
IF EXIST "%PROGRAMFILES(X86)%" (GOTO 64BIT) ELSE (GOTO 32BIT)
"%~dp0WindowsUpdateAgent-7.6-x64.exe" /quiet /norestart /wuforce
wusa.exe "%~dp0Windows6.1-KB3050265-x64.msu" /quiet /norestart
wusa.exe "%~dp0Windows6.1-KB3102810-x64.msu" /quiet /norestart
"%~dp0WindowsUpdateAgent-7.6-x86.exe" /quiet /norestart /wuforce
wusa.exe "%~dp0Windows6.1-KB3050265-x86.msu" /quiet /norestart
wusa.exe "%~dp0Windows6.1-KB3102810-x86.msu" /quiet /norestart
wusa.exe "%~dp0Windows6.1-KB3112343-x86.msu" /quiet /norestart
These patches must be installed.
Then system reboot.
Then kickoff next software update scans (happens on client schedule).
The full package can be made available for download if requested.
