How do I fix reported errors?

I have a Toshiba Laptop with Windows Vista Operating System. It has 8gb ram and processor is dual-core 2300mhz.

In a Youtube presentation, there was mentioned ways to speed up hardware in my laptop. It involved using the Administrator privilege with the command: /sfc /scannow. After waiting for the scan to complete, no hardware improvements were indicated, however there was mention of errors in the following log: \Windows\Logs\CBS\CBS.log

When I attempted access to the log file, I first attempted a command entry without administrator privileges and got an Access Denied. I then attempted access using Administrator Privileges with the same denial.

I am inexperienced with command line computing, but I would like to correct the problem if possible by myself. Will anyone tell me how to access the file and correct any error/errors I find?

Thanks

notepad C:\windows\logs\cbs\cbs.log
for the whole log


findstr /c:"[SR]" %windir%\logs\cbs\cbs.log
for the bits that matter

Copy and paste into cmd as administrator

The portion of the log that relates to problems is as follows:

When I replied to your reply, it did not seem to print, so I am replying again.

I am a 20+ year Linux user and am not very familiar with Windows Operating Systems. If you can and are willing to help more, please advise the impact on my computer created by these problems and how I may repair the damage they created.

Much thanks in advance for any further help. Think of me as a Newbie and explain accordingly. Thank you, friend.
