That's plenty of free space, but if you want to see where space is being used, try a tool like Treesize or Windirstat to get a breakdown.

Just be careful if you want to delete files to free up space. Try the Windows cleanup tool first.

You need 30 GB of free space to do the twice yearly major upgrades.

So get Tree Size (my favorite) or other like Windirstat and find out where your space is going.  

Check for Windows.old folders, but in any event, get rid of what you do not want.

Use CCleaner to clean up your machine.  See  https://www.ccleaner.com/ccleaner  .  You only need the free version.  Only use it to clean out the unwanted files and DON'T use it to clean the registry.  Note you can select which unwanted files to keep or not keep.

That might free up more space for you.  Also see  https://en.softonic.com/articles/9-tricks-to-use-ccleaner-properly

You're just starting to get to the area of not enough room.  10% is not enough while 20% might be adequate.

normally you need free space = 10-15 % of disk size, as John said for updates and work space
so you best clean out some space
you can use windirstat to check what 's occupying space :  https://windirstat.net/
you can also delete all temp, and tmp files; uninstall old , or not used softwares
and a big space saver is moving your pictures, videos, and music to an external disk

without installing any tools can i still debug and see where the maximum memory consumption as i am not allowed to install anything on this laptop?

You may need to get an administrator to help because fixing this and cleaning up space will require admin tools.

you can if you are willing to check each folder, and note its size
command dir can help here  (run it as admin)

here is how to start :  Create a text file listing of the files
Open the command line at the folder of interest.
Enter “dir > listmyfolder.txt” (without quotes) to list the files and folders contained in the folder.
If you want to list the files in all the subfolders as well as the main folder, enter “dir /s >listmyfolder.txt” (without quotes)

The cleanup tool is part of Windows. Otherwise if you are not allowed to fix the problem yourself tell the support team they'll have to fix it. They probably use one of these tools themselves.
