Error 0xC0000034 During SP1 Install

There are some people that are having issues with the latest Service Pack for Windows 7 and Server 2008R2. You may get the error: !! 0xc0000034 !! 142/53007 (_0000000000000000.cdf-ms), even upon a restart. Microsoft has come up with a fix to uninstall the Service Pack:

Option 1 (Win7 client only):  Use a system restore point to recover the system

  • This one is pretty self explanatory.  Boot your machine into WinRE and pick a restore point before the service pack was installed.  This should get you back up and running. 
  • This doesn’t work on server

Option 2 (Win7 client and 2008 R2 server):  Delete the poqexec entry

  • Boot into WinRE and choose a command prompt then run the following commands and restart the computer:
    • Reg load HKLMBaseSystem C:WindowsSystem32configSYSTEM
    • Reg Delete "HKLMBaseSystemCurrentControlSetControlSession Manager" /v SetupExecute
    • Reg add "HKLMBaseSystemCurrentControlSetControlSession Manager" /v SetupExecute /t REG_MULTI_SZ
    • Reg unload HKLMBaseSystem
  • If you’re more graphically inclined, you can use this method:
    • Boot into WinRE
    • Open Registry Editor using regedit.exe 
    • Now you will have the WinRE registry loaded so you need to load the “ System ” hive
    • To do that : Highlight HKLM then  Click on File > Load Hive > Browse to C:windowssystem32config (assuming C: being the system drive )
    • Name the Hive as TEST 
    • Browse to HKLMTESTselect and check the value for “ Current “
    • Assuming the value as (1) browse to HKLMTESTControlSet001ControlSessionManager
    • Locate and double click the key “SetupExecute ” at the right panel 
    • Delete any value inside the key and click OK
    • Highlight TEST and then Click on File > Unload hive
    • Type exit at cmd
    • Reboot the machine and choose to start the machine normally
