Short summary and where to start: several replies (for example , and ) pointed at rescue/restore and reinstall options. Those are reasonable last-resort fixes. Before doing that, try a few targeted diagnostics that usually reveal whether this is a shell/file‑association problem, a per‑user profile issue, or malware blocking system tools.

Quick, non-destructive checks (use Task Manager → File → New Task if Explorer windows won’t open):

explorer.exe
control

If those do nothing, from a command prompt check the Winlogon shell value:

reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v Shell

If the value is not explorer.exe you can restore it (admin required) after exporting the key as a backup:

reg export "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" winlogon.reg
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v Shell /t REG_SZ /d explorer.exe /f
taskkill /f /im explorer.exe
start explorer.exe

Further checks if the quick tests fail: boot into Safe Mode (if things work there the problem is likely a third‑party shell extension or driver); create a temporary user to see if the fault is profile‑specific:

sfc /scannow            (may require install media on very old Windows)
net user TempTest P@ssw0rd /add
net localgroup Administrators TempTest /add
eventvwr.msc

If Safe Mode fixes the issue, selectively disable non‑Microsoft shell extensions (ShellExView or Autoruns are common tools). If nothing helps, then consider the rescue/repair routes already suggested in the thread or a System Restore — but only after backing up user data. Important cautions: always export registry keys before editing, run these commands with an administrator account, and scan with a trusted offline malware scanner if utilities are blocked (malware often targets explorer and .cpl/.lnk associations).

Try using the Ultimate Boot CD for Windows and restoring to a previous restore point. You can download the cd iso here: http://ubcd4win.com/.

What can you do after booting up? There is another thread from a year back with the same problem. Have a search for it.
