Cursor AI slow or freezing on Windows? This fix worked for me

Feedback

:waving_hand: Hi everyone,

I had serious performance issues with Cursor AI on Windows — frequent slowdowns, high disk usage, and dozens of Cursor.exe processes.

After several tests, I found a simple but very effective solution that completely fixed the issue for me.

:triangular_flag: What I was experiencing:

  • Cursor got slower over time or completely froze
  • 25–30 Cursor.exe subprocesses running
  • Internal SSD (C:) was constantly saturated
  • Setting CURSOR_MAX_WORKERS had no effect

:white_check_mark: My solution:

1. Moved Cursor’s cache to an external SSD (F:)

  • Moved the folder:
    C:\Users\<username>\AppData\Roaming\Cursor → F:\Cursor_Cache
  • Created a symbolic link:
mklink /D "C:\Users\<username>\AppData\Roaming\Cursor" "F:\Cursor_Cache"

I had the same exact problem, and moving the cursor cache to another drive that wasn’t my system drive provide performance relief instantly. Runs good as new. Thanks for the tip.
