Slow startup, SFC question

With SSD, my Lenovo has usually started up super fast. But recently I have had problems. I get to the log-in screen quickly, but once desktop comes up, things slow down:
- it is taking longer for wifi to connect
- once connected, nothing works for quite a long time - sometimes over 5 min.
- Hitting Ctrl/Alt/DEl does nothing - sometimes later screen does come up, but too late to see what might be running
- Sometimes have to shut down using ON button or pulling battery.
- Eventually after a slow start, thing get back to normal.

I eliminated some startup items. Googledrive sync?(2 entries), Skype and something that just said default
Seems better. I always had Skype in there. Recently Google said to upgrade Googledrive. Don't know what default is but after deleting it, it just comes back. It is in HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Run and there is just blank line.

That is where I am.

Decided to run SFC /verifyonly - Received this message:

Verification 100% complete.

Windows Resource Protection found integrity violations. Details are included in

the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log

Tried to access that log but get message: Access denied! How do I overcome that? I was able to run SFC with administrator rights, but not read the log? Tried opening it from cmd with admin rights - still no luck.

Decided to run SFC /Scannow

C:\Windows\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files and successfully repaired
them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log

Says it was repaired! But still don't know how to access CBS.log.

Hi Freeagent,
try this command mode should output the file to your desktop


copy %windir%\logs\cbs\cbs.log %userprofile%\Desktop\cbs.txt

That worked! Thanks. Problem now is to interpret just what was done. But seeing SFC said it fixed some issues, perhaps I will first see if problem has gone.

Glad to have SFC find and repair some errors. But slow start was, it seems, something else.

I have two printers. One an old HP 870Cxi that I sometimes use for B&W document printing. Some time back it jammed and would not run, so I switched to newer printer. However, there was still one print job waiting and the old printer was set as the default. USB connection was also disconnected. I suspect system was bogged down trying to figure this out.

Well, I hope that is what it was. Last two starts were good.
