General Computer Support / Re: Windows 7 Pro SP1 64 bit.... Plug and Play service won't start

SUCCESS!

Ok, so after manually replacing the corrupt files identified by SFC there was no change in behavior.  I dug into the actual dll's used by the plug and play service and manually replaced those. Which was only file: umpnpmgr.dll.  This resolved my issue, on next reboot the Plug and Play service fired up.  Now the interesting thing is that not a single piece of diagnostic software could tell this file was corrupt.  I almost didn't replace it either because the number of bytes of the corrupt file matched exactly with the file I replaced it with. 

Maybe this post will help someone else, as for me I am thrilled to not have to rebuilt a development machine!

General Computer Support / Windows 7 Pro SP1 64 bit.... Plug and Play service won't start

« on: November 12, 2013, 07:19:51 pm »

Hello Everyone,

I am at my wits end.  My windows 7 box is telling me that the Plug and Play service has failed that my computer is going to restart.  Fortunately, I found a way to stop the rebooting cycle, by quickly running "shutdown -a".  Now I can start to look around and try to figure out what is going on.

A quick check of the services list shows the Plug and Play service is in fact not running. Trying to manually start it results in the same error message.

Here is what I have tried.

- IOBit Advanced System care registry and disk scanning
- CHKDSK
- SFC /scanow (reports 4 corrupt files, wercplsupport.dll, sbdrop.dll, SPInf.dll, sortkey.nlp ) (I have not replaced these yet, still working out how exactly)
- Windows Defender Offline
- Tweaking.com All In One
- Windows repair install (cannot run without the Plug and Play service)

Open to any and all helpful ideas.

I've already resorted to the fact that I probably won't be able to repair this. However, I don't want to stop trying. There has to be a way to fix it!
