Git is an open source distributed version control system, which can effectively and quickly handle the project version management from very small to very large. Through git, you can upload the code to GitHub, and control the version through GitHub iteration. And the use of every software, always inseparable from the installation, the original git installation is very fast, belongs to the “fool type” installation type. But Xiaobian found that there was no problem when installing it in Xiaobian’s notebook, but when it came to the desktop, it was found that there was a problem. The same win10 system, why the effect is not the same?
After Xiaobian asked Du Niang, someone said C/window/system32/drivers on Du Niang/ null.sysnull.sys This system file is corrupted. So I copied one from other computers, and it still didn’t solve the problem after I covered it. So, Xiaobian continued to ask Du Niang, and found a real solution. Xiaobian’s personal test was effective, so I’d like to introduce it to you.
1. In Windows/system32/ cmd.exe Open CMD, run SC query null
2. Start the service manually, and run SC start null
to find that the small blackboard reported an error:
[SC] startservice failed 577:
Windows cannot verify the digital signature of this file. Some software or hardware has been changed recently. It is possible that the wrong signature or damaged file has been installed, or the installed file may be malicious software of unknown origin.
After that, copy one from another system null.sys And cover the original C: windows, system32, drivers\ null.sys File, and then start the null service. If you want to test null.sys Whether it is normal or not, run SC start null. If the display is similar to the following, it indicates that the startup is successful.
SERVICE_ NAME: null
TYPE : 1 KERNEL_ DRIVER
STATE : 4 RUNNING
(STOPPABLE, NOT_ PAUSABLE, IGNORES_ SHUTDOWN)
WIN32_ EXIT_ CODE : 0 (0x0)
SERVICE_ EXIT_ CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_ Hit: 0x0
after that, right-click git bash here to find that there is no flash back.
It’s useful to make a personal test null.sys File address:
