Trop de cachette de Windows Vista, mauvais ting ? Bien, apparent oui, par excessif caché écrivez l'entrée-sortie et l'entrée-sortie lue cachée excessive. Comme vous savez probablement à ce jour, la cachette est reliée à amplifier l'exécution des processus d'accès aux données qui visent des supports de stockage lents. Dans un scénario idéal, les données ou les pages de code seraient complètement plac dans la mémoire système. La vitesse à laquelle des données sont accédées, dans la RAM physique, excède de loin cela des processus semblables qui impliquent un disque dur, par approximativement 1 million de fois. Mais, en raison de la quantité habituellement limitée de RAM, le logiciel d'exploitation devra traiter la cachette de système. (plus…)

Bien qu'il soit pratiquement handicapé en termes d'options il fournit réellement à l'utilisateur par rapport à Windows XP, l'utilité de defragmentation de disque dur dans Windows Vista est une évolution de l'équivalent du logiciel d'exploitation de prédécesseur. Mais les perfectionnements relèvent essentiellement du capot de l'outil. Dans ce contexte, le moteur réel de defragmentation a été accordé vers le haut, comme la gestion du procédé de fragmentation.

« Par défaut, les defragments d'outil de defrag seulement classe plus petit que 64 méga-octets (mb). Par conséquent, le mb que 64 de dossiers plus en grande partie ne sont pas déplacés inutilement. In earlier versions of Windows operating systems, if the defrag engine was in the middle of a large move request, it could take lots of time to cancel defragmentation. In Windows Vista, the defrag engine processes input and output requests in smaller portions. Therefore, you can avoid situations where the defrag engine is busy with processing large move requests when you cancel a defragmentation session”, Microsoft explained. (more…)

When troubleshooting any version of Windows, learning what applications and processes are loading on startup is a critical step. To this end, the old and faithful MSCONFIG application is a great help, and it’s definitely present in Windows Vista too. Just go Start, Run, MSCONFIG and you’re there.

However times change, and while MSCONFIG is a very useful little utility, there are better options available. Enter Autoruns. Developed by Mark Russinovich and Bryce Cogswell of Winternals (now Sysinternals and owned by Microsoft), Autoruns is a fantastic freeware app which does a full scan of your system and presents you with a total rundown of everything that happens on system startup and system logon.

Every once in a while you notice that your hard drive is working extra hard for what seems like no reason. A background process has taken your hard drive hostage, forcing it to thrash loudly as it struggles to keep up with the high rate of reads and writes. Your computer responds slowly as the process overloads the physical limitations of your drive. What are you to do?

The solution is simple, although a little tricky at times: identify and stop the process that is killing your drive. There are two methods and tools that you can use to identify the process. (more…)

Previously (here and here), I've written about isolating shared services so that they run in their own process, with a specific focus on the Windows Update Automatic Updates Service (wuauserv) that typically runs in the NETSVCS SVCHOST.EXE instance. One thing that can be done once this is accomplished is to lower the priority of the process so that when the service winds up consuming 100% of the CPU, the system doesn't become unresponsive.

Since we're dealing with a service, setting the priority of such a SVCHOST.EXE process can become problematic - the service may already be running, or, because it is a service, it is not started as non-service processes are, so one is not able to use START / [LOW NORMAL HIGH REALTIME ABOVENORMAL BELOWNORMAL] to impose a priority when the process starts. One can use a utility like Task Manager or Process Explorer to set the priority of a process on an ad hoc basis, but when the service restarts or the system reboots one has to remember to set the priority again.

Though not an ideal solution the following scripts (VBS using WMI, and PowerShell) can be used to set the
