As advised, follow the forum sticky first. Below is a focused triage sequence for the symptom where Task Manager is the only UI available; the aim is to (1) restore Explorer so the desktop is usable, (2) make that change permanent by correcting the shell setting, and (3) scan for malicious changes that may have caused the problem.

Temporarily restore Explorer from Task Manager: use File → New Task (Run...) and start

explorer.exe

If the taskbar and icons return, immediately run regedit (also via Task Manager), export the Winlogon key at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

and verify the Shell value is explorer.exe. Also confirm Userinit points to C:\WINDOWS\system32\userinit.exe, (note the trailing comma). Fix any incorrect values, save a registry export first, and reboot.

If Explorer will not start or the shell value keeps changing, boot Safe Mode and run a full antivirus scan plus a second-opinion scanner (for example, Malwarebytes). From an elevated command prompt run:

sfc /scannow

(Windows XP may request the original CD for replacement files). Check C:\Windows\system.ini with Notepad for any rogue Shell= lines and correct them only after exporting a backup copy.

If the problem persists, use System Restore to roll back to a known-good point or create a new local administrator account to test for profile corruption. Avoid running aggressive removal tools unless directed by an experienced helper. After the sticky’s recommended diagnostics are completed, fresh logs will be needed for further analysis of remaining startup items and helpers.

It is recommended that you follow the steps in this sticky first;
Read me before posting a request for assistance
Once you have completed all those steps then come back to this thread with the requested logs and post those, then we can better help you.
Give us some more information about the computer also...hard drive size, how much RAM, etc.
