   There are many reported issues about Windows Drive (C:) eating up a lot of space automatically. Windows 10 users experience this issue once they start updating their PC, especially from a previous version of Windows. But it can also be due to other issues like malware infections, corrupted files, too many temporary or cached datas or a large file that you stored in a C drive folder unknowingly. This issue can get worse resulting in frequent software crashes and lags. Here are some methods that you can try to reduce your Windows C Drive storage consumption:

   METHOD 1: CLEAN UP JUNK FILES AND TEMPORARY DATAS

   • Press “Windows Key+R” to open up the Run command.
   • Type in these commands one by one and once the directory source opens, Use the shortcut key “Ctrl+A” to select the whole files and then use ” Shift+Delete” to delete the files permanently.
   • The commands are: “prefetch”, “%temp%” and “temp”. (Exclude the double quotes”.
   • Once it’s done, Go to search bar and type in “Disk Cleanup” and press Enter.
   • Once the Disk Cleanup window opens choose the files that you no longer want in your system and press OK. Confirm the choice by selecting “Delete Files”.
   • You can also use softwares like Glary Utilities to clean up junk files. The software also comes up with a lot more features that might help you.

   METHOD 2: SCANNING THE PC FOR VIRUS OR MALWARES

   • As I’ve stated, Virus / Malware infections can also be a cause to this problem.
   • Even though you might think your PC is free of any viruses, Scanning your PC won’t take much effort.
   • Use any Antivirus softwares or use Windows Security to scan for any Virus or Malware infections. Make sure to do the full system scan.
   • Also, Make sure that you’ve upgraded your Antivirus security patches to the latest version before proceeding to scan.

   METHOD 3: CHECK FOR DISK ERRORS AND UNUSED PARTITIONS

   To Fix Hard Disk Errors:

   • To check for any Hard Disk errors, Open and run Command Prompt as an administrator.
   • Type in the command: “c: /f /r /x” and press enter. ( Exclude those double quotes and note that there is a single space before every “/” in the command).
   • This will check for any errors and will fix them automatically. If they can’t be fixed, which happens in most of the situations, you might need to contact your PC support.
   • You can also do this in Glary Utilities.

   To Check For Unused Partitions:

   • Type in “Disk Management” in Windows Search Bar and press Enter.
   • Once Disk Management opens, You can see the list of partitions from your system.
   • If you notice any unused or unwanted partion, right click the partion shown at the bottom and choose “Delete”. This will delete the partion and might solve the issue.

   If none of these methods worked for you, It might be due to Windows Updates and previous updates files and I recommend you to reinstall the Windows again which you can learn from here.
