I currently have Microsoft office 2000 premium, Microsoft office professional Plus 2010, Microsoft office professional Plus 2013 installed on my HP, can i remove any to free up space

Hi,

Yes, we can remove the previous version of Office (Both of Microsoft office 2000 premium and Microsoft office professional Plus 2010)

PS: Office 2000 has the different file format with Office 2010/2013, but we sill can open them with Office 2010/2013.
