How do I remove Microsoft Office 2010 "without a trace"?

by Michael45512 / November 18, 2011 9:52 AM PST

Hello, I recently encountered a nasty problems with Microsoft Office 2010 because of a virus. Therefore I must remove Office 2010 completely.

How do I remove EVERY SINGLE TRACE of Office 2010 (including EVERY registry entry, file, information, activation history, etc.)?

P.S.: Basically, the computer should exist in a state as if Office 2010 was never installed.

Thank you!

System Restore

I don't see any other 'foolproof' way of removing all traces.

We never recommend scanning through the registry to remove all traces. That can cause no-end of problems.

So, first of all use the Office 2010 CD to uninstall it, then reboot afterwards. If that doesn't do it, use System Restore to restore back to a time before it was ever installed.

Wouldn't it be better to tackle the virus?

I receive an error.

In reply to: System Restore

I did attempt to reinstall Microsoft Office 2010 (it is a trial), but I receive the following message:

"Error 25004: The product key you entered cannot be used on this machine. This is most likely due to previous Office 2010 trials being installed."

I did not install any previous trials. Therefore, I need to remove the activation signatures and information in the registry.

By the way, I removed the virus, but the damage is still there and I did not have any System Restore points that went back to before Microsoft Office was installed.

It's up to Microsoft to fix this.

no other help can be given.

The version of Office 2010 you have is a Trial Version, by your own statement, and also by your own statement you attempted to reinstall it, so therefore it has been installed on your system before. After a certain defined period of use the trial ends and certain functions are disabled. If you want to continue using Microsoft Office you need to purchase the full retail version.

We cannot assist in circumventing Microsoft Terms on this, It is not a bug that Microsoft needs to fix and neither is it a mess they created. It is by design.

Sorry, but I am locking this thread. If you feel I have missed anything relevant then send a report on this post using the yellow triangle icon bottom right of this post, to send a message.

Seems a strange requirement.

The only foolproof way I know of is to do a clean install of Windows from the Microsoft DVD or the maker supplied recovery media (assuming that didn't contain a trial copy of Office 2010).

I got your email

You say that you were only 37 days into the trial period.

I don't pretend to understand the problem here but I have re-opened the thread so that others can discuss.

However my own feeling still is that the trial period has ended and so you cannot reinstall Office 2010 Trial.

I will delete any posts that offer workarounds.

Have you considered Microsoft's Office 365?

It is a Cloud based version of Office and is available on a 30 day Trial period.
