And then there??™s the program itself, which must read through all your fonts
(the fewer the better), load its own add-on components (DLLs, plug-ins, etc.),
and allocate its own section of your hard disk to store temporary files.
But there??™s also something else at work here, something that isn??™t strictly
necessary. Windows Vista includes an ???Application Compatibility??? system
that checks each program you run against a database of known issues, and
warns you if there??™s a potential problem. This takes time and resources, and
is really only useful when you??™re installing or running older programs not
specifically designed for Vista.
Once you??™ve set up your PC and tested it with most of the software you??™ll be
using on a daily basis, you really don??™t need the Application Compatibility
system any more. Turn it off, and that??™s one less thing Windows needs to do
each and every time you start a program.
Open the Start menu, type gpedit.msc into the Search box, and press Enter to
open the Group Policy Object Editor.* Expand the branches to Local Computer
Policy ??? Computer Configuration ??? Administrative Templates ???
Windows Components ??? Application Compatibility. In the Application
Compatibility section, double-click the following settings to configure them:
Turn Off Program Compatibility Engine. Set this to Enabled to turn off
the system that checks each program you run, and allow programs to
start more quickly.
