Understanding the CBS log & repairing corrupt files

I've been getting some event errors lately, in particular 2 errors.

Date: 10/21/2019 8:54:17 AM
Type: ErrorEvent: 1020Source: Microsoft-Windows-Perflib

The required buffer size is greater than the buffer size passed to the Collect function of the "C:\Windows\System32\perfts.dll" Extensible Counter DLL for the "LSM" service. The given buffer size was 34008 and the required size was 45368.

Date: 10/21/2019 2:07:45 PM
Type: WarningEvent: 1008Source: Microsoft-Windows-Perflib

The Open procedure for service ".NETFramework" in DLL "C:\WINDOWS\system32\mscoree.dll" failed with error code The system cannot find the file specified.. Performance data for this service will not be available.

So I went to https://support.microsoft.com/en-us/...rrupted-system and ran

sfc /scannow

I got the message:
Windows Resource Protection found corrupt files but was unable to fix some of them.For online repairs, details are included in the CBS log file located at windir\Logs\CBS\CBS.log.

I tried to follow the rest of the steps listed on the support page, but got lost in the details.

1. When I used an elevated Powershell & ran the suggested command, I got:

PS C:\> findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

out-file : Could not find a part of the path 'C:\%userprofile%\Desktop\sfcdetails.txt'.At line:1 char:1+ findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\s ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OpenError: ) [Out-File], DirectoryNotFoundException + FullyQualifiedErrorId : FileOpenFailure,Microsoft.PowerShell.Commands.OutFileCommand

2. I manually went to C:\Windows\Logs\CBS & opened CBS.log.There was so much detail that I couldn't follow what was corrupt. I've attached the log.

I would appreciate anyone telling me what files are corrupt & how to replace them. Thank you in advance!
