Windows 10: Windows 10 32bit to 64bit

installed 32bit but need and have capacity for 64bit -is this possible?

:)

 

32bit or 64bit

Windows 10 64bit you can load 32bit and 64bit applications

Windows 10 32bit cannot run 64bit software, therefore you cannot run apps like QuarkXpress that only come in 64bit versions

64bit Windows can address in theory 16.8 million terabytes

32bit Windows can only address 4GB of which 3.12GB may only be usable depending on the version of Windows you are running

In theory 64bit is much faster than 32bit as a 64bit data word (64 1's and 0's) is processed at each cycle of your processor instead of a 32bit data word. I say in theory as there is

A lot of modern software is now optimised to run on a 64bit processor, therefore will run faster, it took a long time for software manufacturers to re-configure their software to take advantage of 64bit

Basically, if you have the option of running either 63bit or 32bit, you have nothing to lose and everything to gain by choosing the 64bit version . . .

 

Windows 10 32bit and 64bit

I have two similar problems. I have several Windows 7 64bit systems and I need to switch back to 32bit because of driver issues. I have no problems with 32bit Windows 10 but it appears it will not allow me to update a 64bit W7 installation to a 32bit W10
installation.

In addition before we found the driver problem we upgraded several computers to Windows 10 64bit.

In both of these cases how do we change/update the installation? If I create an .iso file for a DVD will that allow a clean install from 64bit to 32bit?

32bit to 64bit

You can run 32bit Setup from a 64bit desktop because a 32bit program can run on 64bits so a "down"grade will run.

But you cannot run 64bit Setup from a 32 bit desktop because a 64bit program cannot run on 32bits, so Bilal's reply is correct since the OP is going from 32bit to 64bit.

When, as in your case, you go from 64bits to 32bits you may find you have a Programs (x86) folder, which a 32bit version of Windows should absolutely not have. There are other anomolies. It is because the 32bit installer cannot remove certain 64bit elements
of the old OS.

It is not a good idea to "down"grade the architecture. It is safer to do a clean install of 32bits.

You may have a confused OS. I have done this (back when 64bit Windows first released) and I have no confidence in the results.
