Assume there is a PC/system with 2 drives. One drive is Drive C, which is a fast SSD that has Windows 8.1 + all updates installed on it. The second one is Drive D, which is a slow HDD with a bunch of user data that needs preservation (no format!!!) and Windows 7 that needs updates. The slow Windows 7 HDD came from another computer. Is there a way to update that Windows 7 without having to boot from it? If so, then how??? Again, the HDD cannot be formatted. Please let meknow ASAP! THANKS!
Not sure, but you can try this from RE: Code: d:\ -> Windows 7 Partition e:\ -> SSD dism /image:d:\ /scratchdir:e:\ /Add-Package /Packagepath: <msu_file>
With dism it can be done from within Win 8.1 the way Tito described. Although it should be: Code: dism /image:d:\ /scratchdir:e:\ /Add-Package /Packagepath:<msu_file> (no space between /Packagepath: and the actual path to the .msu)
