Windows 7: Win 7 x64 installed, can I go to the 32?

I have Windows 7 x64 installed in a computer. When I bought it, it came with both the 32 and 64 versions. I registered the 64 and would like to delete it and go with the 32. Would that cause an activation issue?
Thanks.

If it is a legal registration and you have the discs there is no issue going from 64 to 32 bit.
I went the other way ...I loaded 32 and then later went to 64.
Check in the search box above on how to properly go from 64 to 32 but do a back up before you start.

Thanks a lot. I just wanted to make sure.

You'll have to do a clean install, but it will work and be legit. I'm curious though, why are you going in the opposite direction as most people? Nine times out of ten, when someone is downgrading (or going back to x86), there's a way around whatever issue they are running from. Based on your system specs, you'd be giving up almost 1 GB of your system memory right off the bat.

I have a motherboard that can only take 2G memory. It seems to swap a lot as if there is not enough memory. By going to 32 that requires less memory, I should be able to get better performance.
Why do you think I'll be giving up almost 1G?

because you have 4GB listed in your system specs, which is probably not the computer you are talking about in this thread since the board listed in your profile can take 16GB.

you should state that you are talking about another machine when asking questions, since we all look at the system profile of the poster to help them out.

Go for it. Wipe the HD to get the cleanest possible slate, then boot the DVD to clean install.

You are right this is another machine, I forgot about the profile info.
I may try something else first. Install a video card and stop using system memory for the motherboard video. It will free some memory, it may take care of my problem.
Thanks to all.

Yep, that's where I got the info that you were running 4 GB of memory. However, given that it is another computer altogether, that maxes out at 2 GB of system memory, there's little reason to use x64. You won't be hurting anything, but x86 would run just as well. I have two older laptops that were given to family members that max out at 2 GB, both are running x86 versions.

One more question. How about sticking a flash drive for "ready boost" permanently. Would that help? I have several, none of them is exceptionally fast but I could get a new one just for that.
