What is Lenovo Service Bridge and why do the automatic "download update" or whatever they are seem to be happening rather frequently?

 

Thanks!

I can't say why the program is updating frequently but as far as what it does check the below link.

Thanks for the response.  My initial question is what I'm attempting to clarify:  Some www.comments claim LSB does this or that wonderful thing for my computer while others strongly recommend uninstalling it . . . so how does one determine what is true?  Since none of the other programs installed in my computer do updates as frequently as this LSB, it causes me to suspect it may not be a fully trustworthy process taking place.

From the description it's used by Lenovo's technical support to retrieve your serial number and model type. It's probably uploading some things to Lenovo and also runs in the background to check for updates. If the only info it retrieves is the model and serial number you can delete it if you have no intention of calling Lenovo for support.

ROUND II:

 

PC / Windows 7:  
1.  Wondered why automatic "download update" or whatever they are messages seemed to be appearing rather frequently;
2.  Asked on a couple of on-line forums; was told that ""Lenovo Service Bridge (LSB.exe) is a Windows program that will automatically detect your Lenovo computer's serial number, machine type and model. It then passes this information to our website so that we can better assist you with your support needs."
3.  So?  I do not have a "Lenovo computer"!  Why is this program on my PC attempting to gather information to "better assist [me] with . . . support needs" I have not known I had??
4.  So, since on-line info from different sources was inconclusive about whether the LSB.exe business was necessary, I uninstalled it and deleted any "Lenovo" listings found in regedit.
5.  Then this morning, when booting up the PC, I'm presented with:
ERROR SUMMARY
    Below is a summary of the errors, details of these errors are listed later in the log.
    * Activation of C:\Users\NE\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Lenovo\Lenovo Service Bridge.appref-ms resulted in exception. Following failure messages were detected:
        + Could not find file 'C:\Users\NE\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Lenovo\Lenovo Service Bridge.appref-ms'.
6.  Canceled the message popup and cannot see that this supposed error has any effect on operation.
7.  So:  if this supposed "service bridge" is so all-critical to happy operation of MS's Windows 7, why is there no confirmation of that anywhere? and why do supposed people-in-the-know recommend uninstalling the program (makes sense to me since I have never had any known "support need" regarding it)? and why does the ERROR MESSAGE now claim that removal of LSB is A Great Problem?

Any response direct to the issue stated here will be appreciated!  Thanks.

OEMs (HP, Lenovo, Dell, etc.) typically install a number of items on the systems they build/sell...that have nothing at all to do with the running of Windows.

 

Many ttypically refer to this as "bloatware" and expect it to be installed on any OEM system.  The usefulness and desire for such...well, you'd have to ask those questions at the respective OEM user forum.

 

In your case, that means a Lenovo-user forum.

If you do not have a Lenovo I have no idea on why you have this software. What is the make and model of the computer? Did the error on file not found happen after uninstalling Lenovo Service Bridge?

 

The next time you get a notice on automatic update please post a screenshot using the snipping tool of Windows 7.

Download AutoRuns and search for anything Lenovo. Do not delete anything. What was found? What is the make and model of the computer.

I am not sure how else to proceed. I would think Lenovo would be listed in AutoRuns as the error opens when Windows starts, correct?  Is there any listing for Service Bridge under any of the tabs.

 

Are there any Lenovo entries under All Programs > Startup

Please download MiniToolBox  , save it to your desktop and run it.
 
Checkmark the following checkboxes:
  List last 10 Event Viewer log
  List Installed Programs
  List Users, Partitions and Memory size.
 
Click Go and paste the content into your next post.
 
Also...please Publish a Snapshot using Speccy taking care to post the link of the snapshot in your next post.

   Go to Piriform's website, and download the free version on the left.  Click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version. You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.

    After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
 
     Once inside Speccy, it will look similar to this (with your computer's specifications, of course):
 
post-33068-0-86653600-1480692866_thumb.j

     Now, at the top, click File > Publish Snapshot.

     Click Yes > then Copy to Clipboard

Now, once you are back in the forum topic you are posting in, click the ADD REPLY or REPLY TO THIS TOPIC button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.

Yo -

 

Futzed around with AutoRun for a bit, and it seems to have "ferreted out" the offending item(s) -- no more messages when I boot up now.  So, thanks to each!

 

Now y'all can take the rest of the week off . . .

 

Again, thanks.
