Successful 'In Place' upgrade RC -to - RTM
This may well be 'old news' for most but I have not yet seen a post verifying this particular 'MS unsupported' upgrade path, namely from Build 7100 RC to build 7600 RTM. It requires editing a file (cversion.ini) in the sources folder of the 7600 RTM file set. The original file contents read:
[HostBuild]
MinClient=7100
nServer=7100
If one edits it to a similar number lower than 7100 then the RTM install WILL do an in-place ugrade. My cversion.ini file contents are:
[HostBuild]
MinClient=6600.0
MinServer=6600.0
With this simple edit Win 7 build 7600 did present the Upgrade installation choice and proceeded to do so without a hitch. :)
I am posting this for those that choose to do an inplace upgrade from RC to RTM and would oterwise be prevented by MS from doing so. I always recommend a clean install, and do so myself. However through the years I have done many inplace upgrades with no issues.
Upon final reboot the PC this upgrade was done on several days ago, has worked a treat, and has had 0 (zero) issues.
