Windows 7: Can You Tell Me If I Have Saved My PC?

Can You Tell Me If I Have Saved My PC?

My Windows 7 has been put through the ringer. It looks like I might have saved it but I don't know Windows well enough to be certain. My questions to you:

1) Considering SFC and Disc Checks are completing without issue, is Windows back to its old self or do I need to do a clean install to have a truly healthy machine again?

2)
Are there any other steps that I can take to "repair" Windows or the damage done?

What follows is a recount of what happened. This is not required reading. I've done my best to organize it into sections for easy skimming.

How Was It Damaged?
I was having issues with my recycle bin. I decided to empty it via the command prompt but mistyped the command "rd /s C:\%systemdrive%\$Recycle.bin".

It immediately started deleting files from C:\Windows. It took me a minute to figure out what it was doing. I did a hard reset and afterwards trying to get into Safe Mode or Normal Windows resulted in a BSOD. I tried a System Repair Disc but it reported it "could not repair this computer automatically".

What Did You Do To Fix It?

Undeleting Files
I used an EaseUS Data Recovery Wizard boot image to perform a quick scan and restore the Windows directory that was recently deleted. 5.54GB of files were restored to a non-Windows drive.

Copying Files Back To Windows Folder
I used an Ubuntu Live CD to copy the restored files back into the original Windows folder. It never once asked me if I wanted to overwrite an existing file, though some files could not be copied due them being system files (according to Ubuntu). The following files could not be restored:

  1. Windows/pss/boot.backup.LOG1
  2. Windows/pss/boot.backup.LOG2
  3. Windows/ServiceProfiles/LocalService/NTUSER.DAT.rctemp.LOG1
  4. Windows/ServiceProfiles/LocalService/NTUSER.DAT.rctemp.LOG2
  5. Windows/ServiceProfiles/LocalService/AppData/LocalLow/Microsoft/CryptnetUrlCache/Content/94308059B57B3142E455B38A6EB92015
  6. Windows/ServiceProfiles/NetworkService/NTUSER.DAT.rctemp.LOG1
  7. Windows/ServiceProfiles/NetworkService/NTUSER.DAT.rctemp.LOG2
  8. Windows/ServiceProfiles/NetworkService/AppData/LocalLow/Microsoft/CryptnetUrlCache/Content/94308059B57B3142E455B38A6EB92015
  9. Windows/System32/config/RegBack/SECURITY.LOG1
  10. Windows/System32/config/RegBack/SECURITY.LOG2
  11. Windows/System32/config/RegBack/SOFTWARE.LOG1
  12. Windows/System32/config/RegBack/SOFTWARE.LOG2
  13. Windows/System32/config/RegBack/DEFAULT.LOG1
  14. Windows/System32/config/RegBack/DEFAULT.LOG2
  15. Windows/System32/config/RegBack/SYSTEM.LOG1
  16. Windows/System32/config/RegBack/SYSTEM.LOG2
  17. Windows/System32/config/RegBack/SAM.LOG1
  18. Windows/System32/config/RegBack/SAM.LOG2
  19. Windows/System32/config/systemprofile/AppData/Local/Microsoft/Windows/UsrClass.dat.LOG2
Every one of these files was 0 bytes in size. I checked a different Win7 PC and found that these files existed and were also 0 bytes in size.

Running System File Checker
Next I booted into Safe Mode successfully and ran SFC /scannow from the command prompt. It reported success, specifically; "Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log."

Scanning For Drive Errors & Corrupted Sectors
Next I scheduled scans for drive errors. These have finished without any major issues (I assume, I can't find any logs to verify). I have now booted back into Windows 7.

Restoring The Files Ubuntu Couldn't Copy Over
I was able to copy and paste all of the system protected files (listed above) from my EaseUS Restored Files back into the Windows directory (now that I was using Win7 instead of Ubuntu).

The best way to be sure is to do a system restore from before all this happened. If you cannot and everything is as it should be, I would think that you are ok. Chkdsk is not really significant in this situation, but if SFC proves ok, you need not to worry.

I disabled that functionality when I setup Win7. I planned on doing drive images instead, though after a few years I stopped making them. I became too comfortable and lax on my preparations for a disaster like this *lowers head in shame*. Drive imaging will resume as soon as I know I'm in the clear.

Your best shot would be a repair install if you really want to 'save' your pc.

As I said, if SFC checks out and you are not having problems. I think that you are OK. I would just use the computer. Good luck

When I ran the System Repair disc it created a new drive on my computer labeled "System Reserved" and it is 99.9MB. I don't want this on my computer. I'm not sure if this is a partition on my Win7 drive or what. How should I handle removing it?

I would suggest that you do not remove it. That partition could be the factory restoration partition. If you ever have a major problem, it gives you the option to go back to the way everything was the day you bought the computer home.
But it is your computer:

But I built my computer and it didn't exist before I ran System Repair. I plan on using images to fall back on should terror befall my PC a second time. Is there any safe way to remove it, barring the logic it would be unwise to do so?

See prior post
You are in good shape if you use an image. That is my safety net, too. Saved me twice
