There was a problem starting C:\Program Files\Windows Photo Gallery\PhotoViewer.dll The specified module could not be found.
You can create a password reset disk so that you can regain access to the system quickly in the event of a forgotten local account password, without having to use third-party boot environment CDs.
It’s suggested that you create a password reset disk after creating the user account and assigning the password. The password reset disk is not applicable if you have a Microsoft account (MSA); it works for local user accounts only.

Until last week I was thinking that increasing the taskbar thumbnail window size is not possible natively in Windows 7 (and Windows Vista).

We’ve covered the excellent multi-purpose command-line tool NirCmd from Nirsoft earlier. This post talks about the new command-line switches added in the current version of NirCmd. Earlier this month, I sent a NirCmd feature request to Nir Sofer, asking to include an “elevate” switch, which should launch an application elevated (Windows Vista, Windows 7 & 2008.)

Desktop Background Slideshow is a neat little feature in Windows 7 which helps you shuffle your desktop background from a image file store folder, at predefined intervals. But, as Windows doesn’t show the file name of the currently displayed wallpaper, it becomes a problem if you have thousands of images in a store folder and you need to find the file name and the directory location of the currently displayed wallpaper.
Here is a small script which adds the Desktop Background File Location option in the Desktop context menu, which opens the current wallpaper file’s target folder and selects the file.Read more
Aero Shake is a feature introduced in Windows 7 using which you can minimize all other open windows, by clicking on the title bar of an application and shaking it using the mouse. This causes all other applications (except that application window) to minimize automatically. This feature is available in Home Premium, Professional, Ultimate, and Enterprise editions of Windows 7.
If Aero Shake has stopped working on your PC all of a sudden and you’ve tried running the Aero Troubleshooter, here are some other things that you can try.Read more
