Blog Post: Functions broken after Windows 7 or Windows Server 2008 R2 Service Pack 1 (SP1) installation.

Recently, we received several reports that functions were broken after SP1 installation. In most of cases, the SP1 installed with older verion files than the files in the hotfixes for Windows 7 RTM.

So far, the following binaries are affected:

1. inetpp.dll: the latest version on RTM is 6.1.7600.20757, in SP1 the version changes to 6.1.7601.17514. In this situation, the issue described in KB2280758 will re-occur in SP1 bits and you can not install KB2280758 to fix it.

The unsupported workaround is to replace the inetpp.dll in SP1 with the old version 6.1.7600.20757, the sampe script is below (Assume you place the old inetpp.dll in F drive):

@echo on

takeown /f c:\Windows\system32\inetpp.dll
cacls c:\Windows\system32\inetpp.dll /G %USERNAME%:F

net stop "Print Spooler"

copy f:\inetpp.dll c:\Windows\system32\inetpp.dll
icacls c:\Windows\system32\inetpp.dll /remove:g %USERNAME%
icacls c:\Windows\system32\inetpp.dll /grant SYSTEM:RX
icacls c:\Windows\system32\inetpp.dll /grant Users:RX
icacls c:\Windows\system32\inetpp.dll /grant Administrators:RX

net start "Print Spooler"

2. CSC.sys, CSCMig.dll and Rdbss.sys: the latest version on RTM is 6.1.7600.20851, in SP1 the version changes to 6.1.7601.17514. In this situation, the issue described in KB2434932 will re-occur in SP1 bits and you can not install KB2434932 to fix it.

The unsupported workaround is to replace those files in SP1 with the old version 6.1.7600.20851, refer to the script above.

3. Some USB drivers files. For example, the Usbport.sys, Usbehci.sys, and Winusb.sys binary files are not updated. In this situation, you can install KB2529073.

4. Dfsc.sys: the latest version on RTM is 6.1.7600.20714, in SP1 the version changes to 6.1.7601.17514. In this situation, the issue described in KB983620 will re-occur in SP1 bits and you can not install KB983620 to fix it.

The unsupported workaround is to replace those files in SP1 with the old version 6.1.7600.20714, refer to the script above.
