Asked, I created 000 mega in AD and joined the management group, but the landing Win7 was not working.ForLanding Win7, to be a problem, re-activate the record again, the results are consistentLanding Win10, everything's fine.If you are a user, you will be prompted to be free of administrative privileges.1, whether this is a bug, I do not know.2. If you have a plan to upgrade Windows Server 2019, please test it.3, or directly upgrade the following comp

It can be said that in the past few years, the two-level construction division is very hot, but the pass rate is very low, then we want to pass the 2019 exam through the two-level Construction qualification certificate, first of all, the title of the test network to prepare a few on the home 2019 Level Two builder preparation information, to share with you.

Static RAM stores each bit in a bistability memory unit, and dynamic RAM stores each bit to charge a capacitor. Static Ram is mainly used in high-speed cache storage; Dynamic RAM is mainly used in primary storage and fr

platform. 2: 5th Theory I pay attention to five colleagues every day and think about five industry topics every day. Each platform sends five articles, five audios, and five videos each day. 3: cockroach theory During the course of traffic direction, there will certainly be many setbacks and troubles.
