Hey there! @Niranjanjayabal, Thanks for stopping by the HP Support Forums!

I understand after updating your PC you have issues opening applications and you are getting an error- An attempt was made to reference a token that does not exist.

Don't worry I'd like to help you out.

Did you make any hardware or software changes on your PC?

Is your PC connected to the server?

Have you tried checking with a different keyboard?

As you mentioned after updating your PC you have issues opening applications and you are getting an error- An attempt was made to reference a token that does not exist.

Sometimes you try to open "Microsoft Management Console (MMC)" and you receive "An attempt was made to reference a token that does not exist" error.

Try the steps recommended below.

This error may be caused by corrupt files

Here is your Solution:

Open a Command Prompt (CMD) in ELEVATED MODE (run as administrator) and navigate to %WINDIR%\System32 and re-register the required DLL files using the following command:

For /F %s in ('dir /b *.dll') do regsvr32 /s %s

Also, try the steps recommended below.

In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
In Command Prompt, type sfc /scannow. Make sure to include the space between sfc and the /.
Press Enter and wait while System File Checker scans for corrupted files.
When scanning is complete, the results are displayed on the screen.
If the file checker found and replaced any corrupted files, restart the computer and check the performance.
If the file checker did not find any corrupted files or found corrupted files but could not replace them, go to the next step.
If System File Checker finds corrupted files but cannot replace them, use the Deployment Image Servicing and Management (DISM) tool. DISM checks the corrupted files; then downloads and replaces the files using Windows Update.
In Windows, open a web browser.
   NOTE:
You need to be connected to the Internet to use DISM.
In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
In Command Prompt, type dism.exe /Online /Cleanup-image /Restorehealth. Make sure to include the space before each / in the command line.
Press Enter and wait while DISM works. This might take several minutes.
If DISM finds corrupted files, it replaces them using Windows Update. If this occurs, after DISM is finished, restart your computer and see if the performance has improved.
