Device Manager opens and closes repeatedly. If you ignore it, troubleshooting gets noisy, device faults stay hidden, and Windows can look stuck in a restart-like loop. This guide covers common checks and fixes for Windows 10 and Windows 11.

What it means when Device Manager opens and closes

What it means when Device Manager opens and closes
Windows search results show Device Manager with an open option

When Device Manager flashes, disappears, or keeps reopening, the cause may be the Windows shell, a device list refresh, or a driver or service state that keeps triggering changes. The fastest first check is Safe Mode, because it helps separate a Windows shell problem from a device or driver problem.

Why a flashing window is different from a full app crash

A window that appears for a second and closes can come from a refresh loop rather than a normal program crash. If Device Manager never shows a tree of devices, Windows may be restarting the device enumeration process before the interface finishes loading.

What the behavior usually points to on Windows 10 and Windows 11

The same symptom can happen on both Windows 10 and Windows 11 because Device Manager is part of Windows, not a separate app. The Run command devmgmt.msc works across Windows 11, 10 and 7.

Likely causes

Possible causes include the Windows shell or a user profile issue, device enumeration or hardware refresh behavior, and a specific driver or service state. Treat every case as a symptom, not a diagnosis.

Opening/closing pattern Possible cause Exact test to confirm Safest next action
Opens once, then closes before the device tree appears Shell or UI instability Try Safe Mode; if it stays open there, the normal desktop is the problem Use a clean boot, then test a different local profile
Blinks repeatedly, but no device list is visible Device enumeration or refresh behavior Open Event Viewer and look for repeated hardware or Plug and Play errors at the same time Check the driver or service tied to the looping device
Refreshes again after you expand a category Broken driver state Look for a yellow triangle warning icon or a device that disappears and returns Update, then reinstall the driver if the update fails
Closes only in a normal boot Third-party service or startup conflict Run a clean boot and reopen Device Manager Disable non-Microsoft services and startup items

Can you open Device Manager without the window disappearing?

Yes. If the window vanishes in normal mode, try a different launch path first, then move to Safe Mode if the same loop returns. Device Manager can be opened from Windows Search or from the Run dialog, and those paths help separate a broken shortcut from a deeper Windows issue.

  1. Press the Windows key.
  2. Type Device Manager.
  3. Select the result from Start search.

Open it with devmgmt.msc in the Run dialog

  1. Press Windows key + R.
  2. Type devmgmt.msc.
  3. Press Enter.

Try Safe Mode if the window still closes

  1. Open Settings > System > Recovery on Windows 11, or Settings > Update & Security > Recovery on Windows 10.
  2. Under Advanced startup, select Restart now.
  3. Choose Troubleshoot > Advanced options > Startup Settings > Restart.
  4. Press the key for Safe Mode, then reopen Device Manager with devmgmt.msc.

Use the symptom-to-fix table to match the pattern

Match what you see before trying driver updates. If Device Manager shows for two seconds, then drops back to the desktop, that points away from one missing driver and toward a shell or profile issue. If the window stays open until you expand Network adapters, then refreshes again, that points more toward a device-stack problem.

Fast triage checklist

  1. Try devmgmt.msc from Run.
  2. If it closes, boot into Safe Mode.
  3. If Safe Mode works, run a clean boot.
  4. If the loop continues, check Event Viewer for repeated device or service errors.
  5. If only one user account shows the problem, test a different local profile.

Is a driver problem behind the loop?

Is a driver problem behind the loop?
Device Manager shows unknown devices and an update driver menu

A missing, malfunctioning, or unstable device driver can make Device Manager refresh repeatedly, and Device Manager may show a yellow triangle warning icon beside the affected device category. Start by confirming the warning, then update or reinstall that one driver.

Check for warning icons first

  1. Open Device Manager with devmgmt.msc.
  2. Expand the device category that matches the symptom.
  3. Look for a yellow triangle warning icon or a device that appears and disappears.

Update the driver from Device Manager

  1. Right-click the device.
  2. Select Update driver.
  3. Choose Search automatically for updated driver software.
  4. Restart the PC if Windows installs a new driver.

Reinstall the driver if the update does not help

  1. Right-click the device.
  2. Select Uninstall device.
  3. If shown, check Delete the driver software for this device.
  4. Restart the PC so Windows reinstalls the device driver.

Win+X > Device Manager > (device) > right-click > Properties > Driver tab
Update driver
Roll Back Driver
Uninstall device
View > Show hidden devices

How do you rule out Windows shell or service trouble?

Windows Device Manager is open with a menu dropdown visible

If Device Manager stays open in Safe Mode, the issue may be outside the driver itself. A clean boot, a different local profile, or repeated errors in Event Viewer can point to a third-party service, startup item, or profile-specific setting that closes the window before it settles.

Run a clean boot

  1. Press Windows key + R, type msconfig, and press Enter.
  2. Open the Services tab.
  3. Check Hide all Microsoft services.
  4. Select Disable all.
  5. Open the Startup tab and disable startup items in Task Manager.
  6. Restart and reopen Device Manager.

Check Event Viewer for repeated errors

  1. Press Windows key + X, then open Event Viewer.
  2. Go to Windows Logs > System.
  3. Look for repeated entries tied to the same device, service, or Plug and Play event around the time Device Manager closes.

Try a different local profile

  1. Open Settings > Accounts > Other users.
  2. Create a new local account.
  3. Sign in to that account and open Device Manager again.

Still not working? Next steps before you ask for help

If the loop survives Safe Mode, a clean boot, and a profile check, move to broader repair work. Start with system file checks, then use manufacturer driver sources when Device Manager cannot stay open long enough to finish a driver change.

If that didn't work, try this next

  1. Open Command Prompt as administrator.
  2. Run sfc /scannow.
  3. Then run DISM /Online /Cleanup-Image /RestoreHealth.
  4. Get the latest driver from the OEM or chipset vendor site if Windows Update has none newer.
  5. If the problem still returns, use a repair install or contact the device maker’s support team.

Prevention: For recurring driver trouble, keep a copy of the current OEM driver package for the affected device and use it instead of waiting for Device Manager to find one later.

Frequently asked questions

why won't device manager open

If Device Manager will not open at all, launch it with Windows key + R, type devmgmt.msc, and press Enter. If that fails too, boot into Safe Mode and try again.

why does device manager keep opening and closing

A repeating open-close loop can come from the Windows shell, a device list refresh issue, or a bad driver state. Start with Safe Mode, then check for a yellow triangle warning icon and update the affected driver with Search automatically for updated driver software.

how do i stop device manager from refreshing and closing

Use a clean boot to remove third-party conflicts, then reopen Device Manager with devmgmt.msc. If the behavior stops there, re-enable services in batches. If it continues, check Event Viewer under Windows Logs > System for repeated hardware or service errors.

is device manager opening and closing a sign of a driver problem

It can be, especially if one device shows a yellow triangle warning icon or disappears and returns. The quickest check is Device Manager > device > right-click > Update driver. If that does not help, uninstall the device and restart.

how do i open device manager without it disappearing

Open it through Start search or the Run dialog, then test in Safe Mode if the window still closes. Use devmgmt.msc in Run, because that path works across Windows 11, 10 and 7 and avoids broken shortcuts.

what should i do if device manager keeps blinking on windows 11

On Windows 11, open devmgmt.msc in Safe Mode first. If it stays open there, run a clean boot before changing any drivers.
