Yes, the problem was caused by a Windows Update breaking the Windows File Associations pointing the file types to the programs.
Exactly how did you "delete" those trials. I suggest you use the "Fix It" in both of the following tips to do further cleanup of those trials
KB 290301 Uninstall Office 2010
http://support.microsoft.com/kb/290301
2010 If you have 64-bit windows, download the tools to your HD before running them(make copy of your NORMAL.DOTM, EXCEL.XLSM, and for 2010 QAT: Excel.officeui and Word.officeui if you have done any customization).
NOTE: 2 people have said that the Fix It in method 2 would not run in Windows 8.
Method 2 in this tip does a more thorough job that the "normal" uninstall via Programs and Features (aka Method 1 in the tip). The Normal uninstall is designed with the assumption that you will be re-installing Office. It does NOT delete
everything. It leaves configuration files like NORMAL.DOTM and other templates etc. and it also leaves configuration Registry entries.
·
Method 1: Uninstall from Control Panel
·
Method 2: Uninstall using Fix it 9737366
·
Method 3: Uninstall with the Program Install and Uninstall troubleshooter
·
Method 4: Remove manually
If uninstall of Click to Run Office does not work:
· Start run window: <Win
R>
· Start Services dialog: services.msc
· Locate ‘Client Virtualization”
· Right click, select Properties.
· Set Startup type to disabled and Stop the service.
· Repeat FIX IT from KB 290301

Method 2 in this tip does a more thorough job that the "normal" uninstall via Programs and Features (aka Method 1 in the tip). The Normal, “method 1”, uninstall is designed with the assumption that you will be re-installing Office. It
does NOT delete everything. It leaves configuration files like NORMAL.DOTM and other templates etc. and it also leaves configuration Registry entries.
*****************************
You can have only Word 2002 installed from your Office (or Works) package. The installation will be shown in the the Control Panel > Programs and Features dialog. If you can find Office 2002 there, try doing an Office Repair to fix the file associations. That
should fix the popup when you hover over files.
