AWK / Grep - Exclude lines containing file paths - regex

Question

I have a .txt file that contains lines with different file paths. I want to simple exclude lines containing certain file paths.
The problem is that I don't get around the regex format that is used with the common tools.
sudo cat serv_list.txt | awk '!/C:\\Windows\\system32/' > serv2.txt
sudo cat serv_list.txt | awk '!/"C:\\Windows\\system32"/' > serv2.txt
or
sudo cat serv_list.txt | grep -a -v "C:\Windows\system32\"
I also tried to escape the slashes, but it hasn't worked.
The file looks something like this:
Name PathName ProcessId StartMode
Dhcp C:\Windows\system32\svchost... 784 Auto
ehRecvr C:\Windows\ehome\ehRecvr.exe 543 Auto
defragsvc C:\Windows\system32\svchos... 456 Manual
Audiosrv C:\Windows\System32\svchost.e.. 123 Manual
...
The output should be:
Name PathName ProcessId StartMode
ehRecvr C:\Windows\ehome\ehRecvr.exe 543 Auto
...
Can someone please help me on how I have to modify the awk or grep expression to exclude all lines containing the system32 directory path.
Thank you :)

The service provides COM APIs for independent software vendors to register and record the state of their products to the Security Center service. The Action Center (AC) UI uses the service to provide systray alerts and a graphical view of the security health states in the AC control panel. Network Access Protection (NAP) uses the service to report the security health states of clients to the NAP Network Policy Server to make network quarantine decisions. The service also has a public API that allows external consumers to programmatically retrieve the aggregated security health state of the system.

Answer 1

Could you please try following, written and tested with shown samples in GNU awk.
awk '!/[cC]:\\[wW][iI][nN][dD][[oO][wW][sS]\\[sS][yY][sS][tT][eE][mM]32/' Input_file
OR
awk 'tolower($0) !~ /c:\\windows\\system32/' Input_file
Looks like OP's system doesn't have IGNORECASE option so going with above approach where matching small and capita letter both cases for matching.
Didn't know that it would end up here, since OP's samples were keep changing. Or use grep's ignore option too here.
