Lenovo Thinkpad Laptops Failing to Connect to Wifi

I ran into a recent problem where a Windows 7 Thinkpad would not connect to wifi access points properly. It would connect to the Thinkvantage wifi profile, but networking was unavailable. Wired access worked fine, as did everything else. The problem ended up being the Thinkvantage tools.The advanced wifi settings of the network profile showed a power savings setting of maximum savings. Switching that to medium savings enabled networking. I suspect the laptop would have worked if the WAP was only a few feet away, but this user was over 30 feet away.

Uninstalling Symantec Antivirus Client 10.2 from Windows 7 64bit Without the Uninstall Password

If you attempt to install Symantec Antivirus Win64 from Win 7 without the uninstall password, you'll probably find that people suggest that you change a registry key value:

HKEY_LOCAL_MACHINE\SOFTWARE\Intel\LANDesk\VirusProtect6\CurrentVersion\AdministratorOnly\Security\UseVPUninstallPassword from 1 to 0.

That doesn't really work for the 64 bit variant as the key locations are different. I looked around a bit and found that the key was here, instead:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Intel\LANDesk\VirusProtect6\CurrentVersion\AdministratorOnly\Security\UseVPUninstallPassword

After changing that 1 to 0, you should be able to uninstall without a password.

One Line Windows Touch Command (Windows 7, Windows 8, etc.)

I was looking around the web for an easy way to simulate the unix command touch - but I kept finding old variants that would not work past Windows ME. I worked with the FOR loop in batch scripting. Here's the version that works for me:

To set all CSV files to the current time:

for /F "usebackq delims=|"  %i in (`dir /B *.csv`) do copy %i /B+ ,,/Y

Note: to set a single file to the current date:

copy filenamt /B+ ,,/Y

A lot of sites suggested dir with no /B - but this doesn't work for me in Windows 8.

Of course, you can "touch" all files like so:

for /F "usebackq delims=|"  %i in (`dir /B *.*`) do copy %i /B+ ,,/Y
