Windows: How to generate a SAN certificate via Web enrollment

Active Directory: Reset Expiry Date of an expired Password

Many companies have a policy that require their users to change their passwords regularly (e.g. every 90 days). In Active Directory, this is normally enforced via Group Policy.

Now they want to get more data out of your system. By releasing a couple of "Telemetry" updates, they hope to get the same data from you as they get with Windows 10. In addition, these updates slow down your machine and use disk space. Here is the list you need to uninstall KB3022345 KB3068708 - Replaces KB3022345 KB3075249 KB3080149 To Read more [...]
