Winscomrssrv.dll error at startup after upgrade

2049 Views 6 Replies 3 Participants Last post by  Cookiegal
Hello folks,

I require some assistance with an issue I have been attempting to resolve to no avail.
I recently manually upgraded Windows on a laptop of mine because it refused to download any updates (error 0x80080005) and it even had all options of windows security Virus & Threat protection turned off. After the upgrade completed successfully, the system turned on and windows security immediately displayed some pop-ups of malware detected and remediated. Turns out after this particular incident, the system now started presenting two errors after every startup (startupchecklibrary.dll error and winscomrssrv.dll error). I have managed to resolve the startupchecklibrary.dll error by deleting its corresponding entry in task scheduler. However, I am not able to resolve the winscomrssrv.dll error. Many forums suggest using autoruns from Microsoft but when searching for winscomrssrv or srvhost the program returns no results.
The upgrade was performed from windows version 1909 to version 20H2. I hope I have been able to explain the scenario as clearly as possible and if more information is required, I am more than happy to provide.

Hello grandstream and welcome to TSG,

Disable smart screen if it interferes with software we may have to use:

Please remember to enable when we are finished....


Disable any Anti-virus software you have installed if it stops software we may use from working:

Please remember to enable AV software when we are finished running scans....

Run the following scan, lets see if anything shows up:

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option:

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status... If English is not your primary language Right click on FRST/FRST64 and rename FRSTEnglish/FRST64English

  • Double-click to run it. When the tool opens click Yes to disclaimer.
    (Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"

  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.

Thank you,

Hello Kevin,

Appreciate the time you're taking for helping me out. I ran the scan with the suggested tool. Find attached the output textfiles. I must also mention that I observed that this error presents itself only when the charger is plugged in. Booting up with charger plugged in, gives the error. Booting up without charger does not give any error, but as soon as the charger is plugged in, the error presents itself. Not sure if this is useful. Also note that I ran the scan with charger plugged in but if required I can also try without charger.


Hello grandstream,

Thanks for those logs, continue:

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.

NOTE. It's important that both files, FRST or FRSTEnglish, and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1: This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed.

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.


Download "Microsoft's Safety Scanner" and save direct to the desktop

Ensure to get the correct version for your system....

Right click on the Tool, select Run as Administrator the tool will expand to the options Window
In the "Scan Type" window, select Quick Scan
Perform a scan and Click Finish when the scan is done.

Retrieve the MSRT log as follows, and post it in your next reply:

1) Select the Windows key and R key together to open the "Run" function
2) Type or Copy/Paste the following command to the "Run Line" and Press Enter:

notepad c:\windows\debug\msert.log

The log will include log details for each time MSRT has run, we only need the most recent log by date and time....


Open an elevated command prompt:

Copy/paste the following command at the prompt:

Licensingdiag.exe -report %userprofile%\desktop\report.txt -log %userprofile%\desktop\

put cursor at the command prompt then Right click and select paste, hit enter. Two files will be saved to your Desktop.

Attach the "report.txt" file to your reply. - you can ignore the "" file, it's only backup of data..

Attach those logs to your reply...

Thank you,

Hi Kevin,

As requested...


Hiya grandstream,

Thanks for those logs, what is the current status of your system, any remaining issues or concerns...

Thank you,


One of the reports submitted shows that your operating system is using a KMS volume license which is only for corporate use. Using this for personal use is a violation of the licensing agreement. No furher assistance will be provided as your operating system has been flagged as pirated. The only suggestion we can make is that you change the license to a valid retail one or see if Windows will activate with a legitimate license automatically upon reinstallation.

As there's nothing else we can offer, I'm closing this thread.
