Windows 7: Laggy Windows 7, possibly due to corrupt files

After running cmd and running the program sfc/scannow, I still have an incorrectable error at 29%, so I guess my only option now is to reinstall Windows 7 :/ Guess I'll just back up all the files I can and drivers too.

Yes, that would be a good idea, it will allow you to have a easier install.

When you ran the command "sfc /scannow /offbootdir=c:\ /offwindir=c:\windows" did you confirm the Windows installation on your hard drive really was identified as being on drive C? When booting from alternate media the drive letters assigned are very often different than what you'd expect. Maybe you got that error message because there was no installation found on the drive you specified in that command. Also pay close attention to Method 2, Step 3 in the tutorial posted by A Guy regarding the System Reserved partition and drive letters.

In the end you may find it best to do a reinstall. Hard to say without knowing how damaged your installation is. You have to spend some time to prepare (identify all of your software, license keys, etc.) and then more time afterward setting everything up, but you can end up with a "brand new" system. Pick the install tutorial that best fits your situation and then read through the whole procedure. Make sure you understand each step so that you are properly prepared. Just ask if you have questions.

Yep, I only have a C: drive so I don't see how Windows can be anywhere else :/ But yeah, I plan on simply reinstalling Windows onto my computer and hopefully everything will run as it did before. I am running Windows on a self made computer so is there anything I should be worried about when customizing my install?

Just wanted to make sure you read and understood my prior post; often it's not drive C: when booting from alternate media, even though you always see it as drive C: when booting normally. There's got to be a reason you received that error...

It will run as it did before, after you do the install, unless you've got hardware issues. Just install as you did before and you should have no issues (except I would also do a Diskpart clean command to ensure your drive's MBR is clean (keep in mind this also wipes out references to all data on the disk so make sure it's all backed up)). See here:

Yoshisatu: You have one other option to consider before comitting to a re-install.

The System Update Readiness Tool (SURT) contains updated cabinet files (so it's a large download) that can fix many missing or currupt system files. I use it as a companion to SFC when SFC can't do it's job.

Win7 x86 SURT

Win7 x64 SURT

I provided links to both, but if I read your specs correctly, you'll want the x64 tool

Slartybart, my good sir, you have my thanks. It may be a little early to celebrate but I've surpassed the 29% verification error on the cmd.

Welp, spoke too soon, got another error at 100% :/ I'll try running the SURT and the repair disk again.

Yoshisatsu: So you ran SURT and it completed without error, then you ran SFC?
Did you exercise Option Three in the SFC tutorial? Basically searches the SFC output and writes a short version for analysis. Looking at the short version might tell you whether more SFC runs would help.

Definitely keep everyone up-to-date on your progress. Just a note: unlike the SFC log, you can look at the SURT log. It has a similar format - I tend to just go to the end of the file and work backwards. If there's an error at the end that should provide enough information - but sometimes you have to look back a little farther. I think you can use the same Findstr on the SURT log - just direct it to a different file.

The SURT log is in \Windows\Logs - same place as the SFC log.

Yeah, we'll hold off on the celebrations until your system is stable again.

Oh hey,

Have you rebooted since all these SURT / SFC runs? Worth a shot if one of the files were fixed by SURT, but still locked by the system.

also note that when either of these utils run, they create pending rename and delete files that windows acts upon at some point as part of CBS. I haven't quite figured that out. I have quite a list myself and I'm looking for a way to force windows to process them. I might was well look now since it could help you too.
