Tech Lover 9

Windows 7 includes a new feature called the Fault Tolerant Help (FTH), a clever technology that looks out for unstable processes, detects those that may be crashing due to memory issues, and applies several real-time fixes to try and help. If these work, that's fine - if not, the fixes will be undone and they won't be applied to that process again.
While this is very good in theory, it can leave you confused as some applications crash, then start working (sometimes) for no apparent reason. So if you'd like to check if the FTH is running on your PC, launch REGEDIT, and go to HKEY_LOCAL_MACHINE\Software\Microsoft\FTH - any program currently being protected by the FTH will be listed in the State key.
Experienced users may also try tweaking the FTH settings to catch more problems, and perhaps improve system stability. A post on Microsoft's Ask The Performance Team blog (bit.ly/d1JStu) explains what the various FTH Registry keys mean.
