For years, I’ve loved the freeware utilities put out by SysInternals and Nirsoft. If you have a problem – especially an obscure one – and SysInternals or Nirsoft make a utility that addresses the issue… it’s the only way to go to fix it. Unfortunately, most of their products are standalone command-line apps, and it’s difficult to grab them all and throw them on a flash drive. Or at least it was. The freeware app Windows System Control Center gives them all a nice UI to navigate, so each tool is only a couple of mouse clicks away:
Remember WSCC is only a UI – you’ll still have to download the actual programs from SysInternals and Nirsoft.
