"downgrade" 64bit win 10 to 32bit


I have win 10 home 64bit installed and activation successful. Installed by windows update. before this, on my laptop installed win 7 home premium 64 bit.
What can I do if I want to change win 10 64 bit to win 10 32bit ? I only have cd original win 7home premium.

My RAM only 2 GB, Processor intel atom 1,66Ghz. thank's

Hello viper4100 Welcome to the windowssh blog!

Since 10 Home x64 has already been activated all you need to do now is run the Media Creation tool one or two times again in order to select the Home edition from the list or perhaps the combo 32/64bit in case later you decide you want the 64bit back on again. Here I originally grabbed the combo which is larger and requires a good 8gb or 16gb flash drive not being able to burn to dvd as well as each flavor for both the Pro and Home editions as other upgrades are pending for other people at this end.

If you already made up the 64bit installation key or dvd you can opt for the separate 32biit key to be made up as you go along or choice to save the ISO type disk image file to a folder you have ready to receive it other then the Downloads. Having both flavors saved to the drive will allow you to recreate the media at any time however. And once you have the 32bit media reaady to go you simply need to perform a full clean install not an upgrade over the 64bit!

You can see the drive reformatted as well as long as you have everything backed up on removable media as well as an external hard drive if you have one and with only 2gb of ram I can easily see why you would want to switch over especially you can't add more memory in. Once you are set to go just be sure any other flash drive or external hard drive is unplugged before going to perform the clean install as you will see when looking over the guide for this.

Thank you Night Hawk. your explanation is excellent. Best Regard's from Indonesia

You're welcome! viper4100 Hope everything goes well for you there!

You might still want to backup the laptop and if you have an external hard drive consider making a full system image backup in case something does something does go wrong. With a full backup you could rget everything back on afterwards if something comes up.

Really no need to go from 64 to 32 bit. 64 bit runs well with 2GB of ram.

Why do you want to go from 32 to 64 bit? There is not reason to. It won't affect performance any even with only 2 GB RAM.

It can at times! It depends on what you are running. Increasing the memory from 2gb to 4gb will be noticed right away as far as overall system performance. The 64bit OS tends to preload apps into the active ram while the 32bit does more swapping data out to the drive and why you see page files on the 32bit more so. For that reason the 64bit is often seen as far more efficient.

The OP only has 2GB RAM.
You see more page file swapping on 32 bit OS because it can only accommodate about 2 GB of memory for user programs. If you only have 2GB RAM it won't make any difference.

With the 64bit more ram is taken up automatically when the 64bit preloads adds generally the most often used into the active ram so it appears more memory is taken up. The 32bit Windows can actually utilize 3.571gb on a 4gb system with the remainder being mapped out to hardwares due to the limitations of the 32bit kernel. With XP would have been only 3.120gb available out of a 4gb total.

Now as far as managing a page file in the 64bit Windows with only 2gb of memory installed you then need to calculate how large the page file needs to be. An updated MS support reference goes into detail on that. How to determine the appropriate page file size for 64-bit versions of Windows

You quote those numbers to 3 decimal places, yet the amount of address space reserved for hardware memory mapped I/o varies depending on the particular hardware you have, particularly the graphics card you are using. The OP should be able to utilize the full 2GB of memory because the hardware I/o region will be mapped to addresses above 2GB (4GB and down).

You say that "With the 64bit more ram is taken up automatically when the 64bit preloads adds generally the most often used into the active ram". I would like to see a reference for that claim. I believe Windows prefetching does not depend on whether you have 64 or 32 bit addressing.

64 bit would let you get more that 2GB of virtual space for a program (limited to 2GB for 32 bit), but with 2GB total RAM it doesn't matter.

For managing the page file size - the amount will be the same for either 32 bit or 64 bit Windows with 2 GB of RAM.
