Windows 7, 64bit and older software

  MrNewName 01:16 28 Jul 2009

I have pre-ordered home premium version W7 to install on a new 64bit machine which I hope to get in mid-Oct.

I have a few queries which I can't seem to find answered:

1 - how will WindowsUpdate be available should I choose not to install Internet Explorer? I use Firefox and am pleased with it - I only use IE for WindowsUpdate.

2 - where can I find a list of software that runs (or perhaps doesn't run) on W7? Are there many compatibility issues? I don't run anything out of the ordinary so I'm not too concerned about this.

3 - if I install the 64bit version and don't activate it, can I (within 30 days) format and install the 32bit version if necessary?

4 - main use will be Adobe Lighroom and possibly Photoshop or equivalent so how will it run on the following:

Processor Intel Q9550 Core 2 Quad Processor
Processor Speed 4 X 2.83GHz
Memory 4GB DDR2 800MHz Ram

1 as far as I know WindowsUpdate is a program on its own and will be able to check for updates even if you have no browser .as microsoft and eu have not yet sorted all the details ,maybe you will have a choice of browsers through windows update . just a thought.
2. I dont know for any lists ,but I have tested extensively all the later versions of windows7 in 32 and 64bit .in 32 bit everything works as it did in vista including all my hardware drivers .64 bit wont accept unsigned drivers and has refused several drivers of mine ,I cannot get either of my wireless internet adapters to work .
3. install the 64bit version ,dont use the product key you will have 30 days to test ,if you dont want to keep it simply remove ,microsoft will be none the wiser ,if you install either without using the product key you will be able to do this .once the key is registered ,the key you use will be locked to that system (32 or64) and you wont be able to change. although the wording of the EULA suggests differently ,I believe that to be the case .
4. it should run superbly on your specs. it is noticably faster than vista , and uses memory and multicore processors better .

Thanks for that, in particular #3 hint about not using the product key. Does that I mean I can install it without a key and wait until activation time before entering the key?

I always thought that windows update was tied into IE for some reason; good that it's not any more.
