Disable Superfetch
By accessing a prefetch file, the Superfetch function, also known as SysMain in Windows 11, helps to reduce boot time and load apps more effectively. However, while it is a useful feature that enhances speed, it might result in high disk usage. To deactivate Superfetch (SysMain) on Windows 11, do the following steps:

3 – When the Services console appears, double-click SysMain and then click the Stop button.

5 – Click Apply and OK to exit the Services console.
After pausing SysMain, you should observe a change in Disk Usage in Task Manager; however, you need to restart your PC to make it’s fixed.
Rebuild Search Index
Another typical problem of high disk usage in Windows 11 is search indexing. To provide search results quicker, search indexing examines files, emails, photos, and other system files on your PC. If anything goes wrong, it might result in an infinite search cycle. However, you may repair it by rebuilding the database. To rebuild the search index, accomplish the following steps:
1 – Press the Windows key or click Start, type indexing options, and select the top result.
2 – When the Indexing Options box appears, click the Advanced option.

If the rebuild works but you find yourself performing a lot of rebuilds, you may turn off search indexing completely. Use the following procedures to deactivate Windows Search:

Search indexing is now disabled and will not run if you reboot your PC.

Leftover temporary files may produce excessive disk burden, and removing the files can fix 100 percent of disk usage on Windows 11. To remove temp files from Windows 11, follow these steps:
1 – To launch the Run dialogue, shortcut Windows key + R.
2 – In Run, enter %temp% and press OK.
3 – In File Explorer, open the Temp folder; press Ctrl + A to select everything in the folder, then click the Delete button in the toolbar.
Disable DiagTrack Service
Well, the Connected User Experiences (DiagTrack) service, often known as Telemetry data, operates in the background and sends Microsoft data on your PC usage. Therefore, it might be the source of a high disk usage percentage. Use the following steps to deactivate the DiagTrack service:

Check Malware
Another crucial and most important thing to check for is viruses and/or other malware. The Windows Security (Formerly Windows Defender) is built-in and continuously analyses your system for malware. However, it may only capture some things. You may manually run a virus scan by following these steps:
1 – Press the Windows key or click Start, type windows security, and choose the top result.
2 – On the left, choose Virus & threat protection and click the Quick scan button.
3 – If nothing is found and you still have 100 percent disk usage, run a deeper scan. To do so, select the Scan options link and choose Full scan or Microsoft Defender Offline scan.
A more thorough scan takes longer, but it is worth the wait if your system is plagued with persistent malware. An offline scan will make a restart, so close any open files before you begin. It is also critical to get a second viewpoint. If you’re dubious about a file, run a scan using a reputable and free security app such as Avast or AVG AntiVirus.
Run SFC And DISM Scan
Missing or damaged files in Windows might result in a high disk load as your PC attempts to compensate. Fortunately, Windows has a handful of tools that may help you scan for corrupt files and replace them with good ones. To use these tools, run the following steps:
1 – From the Start menu, right-click and choose Windows Terminal (Admin).
2 – In the terminal, type the following command and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
3 – Once the DISM command has finished, type the following command and press Enter:
sfc /scannow

Another thing you may do to resolve 100 percent disk usage in Windows 11 is to inspect the disk for errors. You may check the disk for errors by following these steps:
1 – In the Start menu, type powershell.
2 – Hover over the top result, then choose Run as Administrator.
3 – When the terminal window appears, type the following command and press Enter.
Chkdsk /r /f
4 – When asked, type Y and press Enter to schedule the scan the next time you reboot your PC.
