There is no confirmed universal fix for a Windows 11 File Explorer crash attributed to PowerToys Peek. First determine whether explorer.exe actually closes or restarts, or whether Peek simply fails to open; those are different problems. Then compare Peek’s Explorer shortcut with its documented command-line launch and record the exact Windows and PowerToys versions before changing settings.
First identify what “crashing” means
Microsoft describes Peek as a PowerToys utility for previewing file contents without opening another application. A failed preview, a frozen Explorer window, and Explorer closing or restarting are not interchangeable symptoms.

- Peek does not appear: pressing its shortcut produces no preview. This is an activation failure, not proof that Explorer crashed.
- Only the preview closes: note whether Explorer remains usable and whether the PowerToys process or Peek window disappears.
- Explorer freezes: record whether it recovers, becomes unresponsive, or must be restarted.
- Explorer closes or restarts: treat this as an Explorer crash and capture the crash record, including the faulting application and module. Do not assume the preview component caused it.
Record the versions and the situation
Before troubleshooting, write down the details that let you reproduce the issue and distinguish it from reports involving different builds or Explorer locations:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Windows version and build.
- PowerToys version and where it was installed from.
- The configured Peek activation shortcut. Microsoft documents Space as the default beginning with PowerToys 0.95, but the shortcut is configurable; check your own setting and version.
- The file type and whether the test file is local.
- Where you activated Peek: a regular folder, Explorer Home, Gallery, or another location.
- Exactly what happened, including whether
explorer.execlosed, restarted, or stayed open.
Compare Explorer activation with a direct Peek launch
Use one known local file for both tests, preferably from a conventional Explorer folder. Microsoft documents a command-line entry point for Peek: PowerToys.Peek.UI.exe <filepath>. Substitute the path to the file you are testing for <filepath>.

- In the Explorer folder containing the test file, select the file and activate Peek with your configured shortcut.
- Try the documented command-line launch for that same file:
PowerToys.Peek.UI.exe <filepath>. - Record whether each method opens the preview and whether Explorer remains open and responsive.
If the direct launch works but the shortcut from Explorer does not, that points toward investigating the Explorer activation path or location; it does not prove a particular root cause. If Explorer itself closes or restarts, save its crash details instead of treating the result as a Peek-only failure. The command is an isolation check, not a Microsoft-prescribed crash repair.
Use toggling only as a controlled isolation test
You can temporarily turn Peek off, or temporarily disable PowerToys, and repeat the same steps to see whether the symptom changes. Treat this as an experiment, not a confirmed fix: the available documentation and issue reports do not establish that disabling Peek resolves this specific Explorer crash. Note the original setting, change only one thing at a time, and restore the prior state after the comparison.

What existing reports do—and do not—show
PowerToys issue reports illustrate why matching the exact symptom and version matters, but none verifies a universal repair for a Peek-caused File Explorer crash.
- PowerToys issue #32147 reports Explorer and Settings crashes with versions 0.78.0 and 0.79.0. It is categorized under General/Settings, not Peek, and names
dwmcorei.dllas the faulting module. That module detail applies to the reported case; it should not be assumed for other crashes. - PowerToys issue #45682 describes intermittent Peek activation from folders on Windows 11 25H2 with PowerToys v0.97.2. It reports activation trouble, not confirmation that Explorer terminates or that Peek caused a crash.
- PowerToys issue #42414 says Peek stopped opening from Explorer Home after a move from v0.94 to v0.95. It concerns a particular activation context and does not establish a fix for all Windows 11 builds.
When to report the problem
If the crash or activation failure persists, report it in the PowerToys issue tracker with reproducible steps. Include your Windows build, PowerToys version and installation source, shortcut setting, file type, Explorer location, the result of both activation tests, and the crash record if Explorer closed or restarted. These details help distinguish an Explorer crash from a Peek activation failure; an issue report by itself is not a diagnosis or a guaranteed resolution.
