Steps

Goal: Find the leaking program, update or reinstall it, and reduce its impact.

  • Restart. Watch Task Manager over hours. Note which process memory grows.
  • Good: Found the program. Update or reinstall.
  • Bad: Disable recent apps one by one until the leak stops.

Restart first

Goal: Clear RAM and establish a baseline.

  • Restart. Note memory in Task Manager. Use the PC normally.
  • Good: Memory grows over hours—you have a leak. Watch which process grows.
  • Bad: Memory stays stable—no leak, or it is very slow.

Find the leak

Goal: Identify which program has the memory leak.

  • Task Manager, Processes, Memory. Use the PC for a few hours. The process whose memory steadily increases has the leak.
  • Good: You identify the program. Update or reinstall.
  • Bad: Disable startup programs and recent apps to narrow it down.

When to get help

Call a technician if:

  • You cannot identify the leaking program.
  • A critical app has the leak and you cannot fix it.
  • The leak persists after reinstalling Windows.

Verification

  • Memory usage stays stable over hours with normal use.
  • No need to restart to free RAM.
  • The leaking program is updated, reinstalled, or disabled.
