<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;">OK, so I “upgraded” (in place) my Vista Notebook to Windows 7 Ultimate (Beta or RC1 – whichever was on the download)</span></p>

<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;">The good news:  I made a full backup ahead of time.</span></p>

<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;">The bad news: I had a lot of weird seizure “issues” post upgrade</span></p>

<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;">The upgrade process itself went very smooth.  Post-upgrade I had issues with machine “seizures” as aforementioned.</span></p>

<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;">After a few hours (non-business hours) of troubleshooting, I finally deduced that it was the Windows Search feature (likely indexing?) causing explorer and the system to hang.  I disabled the Windows Search service and all has been well since (I’ve had to tweak some Windows vs. Trend firewall stuff, and remove some other junk that didn’t come thorugh the upgrade too smoothly, but this is minor and all reinstalled just fine after the fact – things like XenApp PNAgent, VMware Workstation, etc.)</span></p>
<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;"> </span></p>
<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;">I kind of suspect that if I re-enabled the Windows Search service, and let the machine sit over the weekend, it would likely index and be all happy happy.  I’ll probably try that.</span></p>

<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: Calibri; font-size: small;">However, if you upgrade your machine, then a) MAKE A BACKUP, b) note that you may have to disable the Windows Search service at first </span></p>
