RC will ran out in some days ( only kernel patch would help to remove time-bomb ), dude get rtm. ( sorry if this sounds rude )
Yep dude. RemoveWAT along with a lot of other loader tools will not work on the RC. Plus the RTM has a lot of fixes that were found in the RC hence the reason to upgrade the build. Unfortunaltey secr9tos is right and the RC will start giving you bi-hourly shutdowns automatically on March 1, 2010 followed by it shutting down for good on June 1, 2010. So yea get RTM.
Download RTM and use one of the following methods to activate: * Bios mod * OEM Slic driver * Loader e.g Daz' Program based 7 Loader
I would download the RTM from the Official Windows 7 Repository here on MDL(Very fast torrent downloading if you have fast internet) and when you install it either backup all your data and format the HDD to do a clean install(I would recommend that) or run the setup but rather then doing an Update install just install it without formatting your HDD. That will put your old windows 7 folder in a folder called Windows.OLD and keep all the user files\Program Files\ and custom files intact either in the HDD Root or in the Windows.OLD folder. Remember that doing it without formatting will take longer depending on your hardware specs.
