"100% Disk Utilization" means that some processes will consume the entire read/write capacity of the disk and nothing will be left for the others to consume and run smoothly. This inevitably slows down the system as the system struggles to function properly. There are a number of reasons that could be at the root of the problem on your computer. Everything from malware to misconfigured browser settings can trigger this problem. But before you jump to the main, broader solutions, we recommend trying these quick workarounds.
Workarounds -
1. Restart your computer once . Like other users, it can end 100 percent disk usage problem.
2. Disconnect any external media storage devices (like - external hard drives, thumb drives, etc.).

2. Then right-click " Command Prompt " and click "Run as administrator " to open terminal as administrator.
3. When the command prompt opens, type this command in the terminal and press Enter .
net.exe stops "Windows Search"This will stop Windows Search from running in the background. Now open task manager and check if it still shows 100% or not. If you still get the same problem, this is not the cause of your problem and you can move on to the next solution.
However, if disk usage has dropped significantly, you can permanently quit Windows Search .
1. First, press the Windows key and write " Services ".

9. Select drive " C: " from the list of drives.
10. Then click " Custom Size ".
11. Then set the "Initial size" and the "Maximum size" accordingly.
NOTE –
Using this formula, you can easily calculate the approximate magnitude of these parameters.
Initial size (MB) = the recommended size (MB)
Maximum Size (MB) = 1.5*1024* (Installed RAM in MB)
The initial amount of RAM should be the same as "Recommended:". In our case it is –
Initial size (MB) = 2938In our case, this system has 16 GB of RAM or 16*1024=16384 MB. So the “Maximum size (MB)” is –
Maximum size (MB) = 3*(1024*16) = 3*16384 = 4915212. When done, don't forget to click " OK " to save the settings.
13. If a warning message appears on your screen, click Yes .
14. Then click " OK ".
