Windows 7 Windows7 Ultimate (RC)

Since you already installed Pro you can't install it on a second PC. In the last day or so there was a work around to upgrade from RC to RTM versions posted here. I would do a Clean install and avoid problems.

Joe, thanks for the reply. I know that a Clean install is the way to go...just wondering if anyone knew of another way to make the change. cheers and beers

I'd be willing to bet that purchasing a license for the RC, if it were possible, would cost the same as purchasing another DVD.
I don't think MS offers license keys for purchase to make a RC install permanent.
If anyone knows otherwise please post.

Since you are willing to shell out money for a new license purchase another DVD and do a clean install, save your data and be prepared to reinstall your 3rd party apps etc.

Even though Joe S references a method of doing an upgrade from the RC it's not a good idea to do so.
You could carry over issues that will cause problems.
Do a clean install with a new DVD and license.

Frank, thanks for the input. I agree. Better to start fresh out of the gate. I am really enjoying Win7 Pro on my desktop and am using it for this post. Response time is really great. Though I have discovered that my Laptop Aspire 5000 is really dog slow (Win7 Ultimate RC). I tried upgrading RAM and was unable to do so even though the specs for the PC say that upgrading from 1G to 2G is possible (old PC, purchased over 4 yrs ago). I had ordered new sticks of RAM and was unsuccessful in my endeavors. Tried many troubleshooting guides and my results were negative so i sent the RAM back...am hoping for a refund. So I am wondering how to do improve the performance of my laptop...still a good machine, just slow.

BTW, ice pics of your family. Merry Christmas and Happy New Year. Cheers and beers...well eggnog soon!

Thank Billy, That's my granddaughters Olivia and Gabby in my avatar.

I'm truly impressed with my notebooks performance on Win 7 Home Premium.
I've been using Win 7 since the beta and just recently purchased Win 7 Home Premium.
I'm particularly impressed with the quick boot times compared to XP.

I have both Win 7 Home Premium and XP-SP3 Pro installed on my notebook's HDD in a multiboot setup (plus 4 Linux distributions).
Both OS's have startup items limited to the bare minimum with many unneeded services set to manual.

Using BootRacer v2.0 I've measured boot times to fully functional desktop with Win 7 to be around 43 seconds compared to around 95 seconds
with XP.
Since my machine is a notebook and I shutdown after using this quick boot time is important to me.

BootRacer measures time to logon and boot time to desktop.

Merry Christmas and a Happy New Year to you too.
