I may sound dumb, but I went to a website to try and speed up my computer, and I did what it said and I think a couple of important files are missing. when I open Windows Explorer for the first time when I log on, it opans fine until about 30 seconds with it up and it crashes, I open it up again and it has to close straight away, and next time I go to open it up the window doesn't come up just, It Has Encountered A Problem And Has To Close. And also when I log-on, these winodws pop-ups come up with like log-on "something something" then it comes up again after I had to terminate the program and then I did it again and then my wallpaper comes up with nothing else, and to get everything to show, I go Ctrl+Alt+Del and then Add New Task... and just something random...

Can you guys help?

Symptoms reported by (Explorer starting then closing after a short time, desktop wallpaper only, repeated logon popups and needing Ctrl+Alt+Del to start tasks) point at a shell/explorer failure, missing or damaged system files, or interfering startup components. offered an early recovery suggestion and later noted the problem was resolved; the checklist below helps confirm system integrity and reduce the chance of a repeat.

Useful verification and repair steps (run as administrator):

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
eventvwr.msc
  • Check Event Viewer (Application and System logs) for Explorer.exe or Winlogon errors at the times the crash happened; the error details give the best clue.
  • Run sfc /scannow to repair protected Windows files. On Windows 8/10/11 run the DISM command shown first before SFC if system image repair is needed.
  • Do a full malware scan with an up-to-date AV plus a second-opinion scanner (for example, Malwarebytes or an online scanner).

Other practical checks and precautions

  • Verify the shell registry value at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon — the Shell value should normally be explorer.exe. Back up the registry before editing (File > Export).
  • Inspect startup and shell extensions with msconfig/Task Manager (Startup tab) or Autoruns (Sysinternals) to disable unfamiliar items; faulty shell extensions often cause Explorer crashes.
  • Create a new local user account and log in to determine whether the fault is profile-specific.
  • After confirming stability, create a system image or restore point and keep regular backups. Exercise caution with web “speed-up” tools; they can change startup entries or remove components and should be used only if their actions are fully understood.

I already did that as soon as the problem started, and it didn't work. But I fixed the problem now :)
