Running SFC Scannow in system repair, Win7

Posted on by

If you are stuck in a loop where the windows 7 does not boot and the system repair cannot fix your installation , it might be a good idea to run the system file checker.

 

However sfc doesn’t really understand what to do if you just run sfc /scannow from the advanced repair options command prompt.  - We need to tell it where windows is installed.

So choose advanced repair options, command prompt and type:

SFC / SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=C:\Windows

If you have windows installed on another drive than C, change it. For me it was E for example.

If you don’t remember where it is, type c: and hit enter in the command prompt, then type dir and see if you see a folder (A text line) that says Windows if not try again by changing the drive letter, to d: ,hit enter, type dir, hit enter and keep hunting for those files.

Good luck,

Just wanted to say a couple of words about a malware remover I just found.

Roguekiller. (http://tigzy.geekstogo.com/roguekiller.php)

It seems to be quite effective at finding critters and bad thingamajigs on your PC. I had some stubborn malware that gave me popups in chrome and I couldn’t remove it with. Malwarebyte’s AntiMalware. (Which otherwise is a good program).

So, mental note for myself. Roguekiller was the name of the software, and a i think i actually recommend it…

thinking…

yes i do recommend it :)

20Mhz or 40Mhz Channel Width Router Setup?

Posted on by

I had some connectivity problems with my router setup, I’m running two dlink routers as repeaters basically between rooms and floors in my house. Ping between these was really erratical 1ms 1ms 3ms 567ms and so on.

I was running 40Mhz channel width on the n-band.

Even though the theoretical troughput on the routers went down by half from 300 to 150 I still get a much better performance on the link route when i selected 20Mhz.

So, if you are having problems with the wifi signal jumping over many routers, try going 20Mhz on the bandwidth! Let me know your mileage!
