2] Delete Temporary files

Temporary files are created by the programs that we use on our computers. These files are required by the programs to complete the tasks that we perform. Some programs automatically clear these files when we close them. For example, Microsoft Word creates a temporary file when you edit a document or create a new document. When you save that file and exit Word, that file is automatically deleted.

All programs do not delete these files automatically after the completion of a task. The temporary files created by such programs are left as residues on our Windows computers. These temporary files are useless and take space on our C drive. With time, these temporary files increase and start taking more space on our C drive. This not only affects the performance of our system but also creates issues in other programs. Therefore, deleting these temporary files is mandatory.

Delete the temporary files from your system and see if it works. To do so, follow the steps below:

Open the Run command box.
Type %temp% and click OK. This will open the Temp folder directly.
Now, select all the files and folders inside the Temp folder and delete them. Some files will not be deleted as they will be currently in use. Hence, skip them.

After deleting the temporary files, see if the issue is fixed. This solution has worked for some users. Maybe it will work for you too.
