Lost my taskmanager when fixing about blank

i was following a guide posted here, and there was a part that said to delete system32/taskmanager.exe while in safe mode, and i did, and now i have never been able to use it since

can i get it back without installnig wondows again?
thanks in advance

 

That is a legitimate file required by Windows. Personally, I would never delete anything without asking a professional first.

Lets start by trying this:

If your running WinXP try to replace it with the attached file. If not let me know!

Just extract this into C:\WINDOWS\system32

EDIT by chaslang: Attachment remove.

 

To make sure this is not a WORM doing this.

Make sure you have HijackThis 1.99.1 and follow the guidelines on where to install it and how to post a log as an ATTACHMENT.
All instructions are covered in the sticky thread NO HIJACK THIS LOG FILES BEFORE READING THIS: HJT Tutorial & LOG File Posting


Now post a Hijack This log as an ATTACHMENT to your message (Do NOT copy/paste the log into your post). Please close unnecessary running programs before you run HijackThis. You must close each of the following: your web browser, e-mail client, instant messenger, and programs like notepad, wordpad, MS Word etc.

DO NOT run Hijack This from the Desktop, a temp folder, or a sub-folder of C:\Documents and Settings, or choose to run it directly from the downloaded ZIP file. Place it in its own folder, for example C:\Program Files\HJT
