Here is the last version of my TimerStop crack : It works on vista RTM x86 and x64. How to use it: 1- Apply one of the "2099 trick" (eg: set install date to: 2099 and set date back after install...) 2- Unpack the ZIP in a temp directory 3- Launch install.exe It will prompt to launch as admin, since it is necessary to install the driver. 4- Press the "Test" button, don't close the messagebox shown. 5- Launch a command prompt with admin rigths. 6- Type "slmgr.vbs -dlv", a dialog box should popup in 10-20s. 7- Note the number of minutes displayed on the last line, and close the dialog box 8- Wait a few minutes, and type "slmgr.vbs -dlv" again 9- If it works, the number of minutes should be the same. You can then close the messagebox shown in 3, and press the "install" button to run the driver at each start
