Sometimes the program needs the administrator’s permission to do some operations, such as reading and writing to Disk C (log), setting the program to boot automatically, etc. without the administrator’s permission, it may not be able to read and write to Disk C (log) or set the program to boot automatically, etc.

terms of settlement:

Right click the project, properties – & gt; linker – & gt; manifest file – & gt; UAC execution level – & gt; requireAdministrator (/ level =’requireadministrator ‘)

To be solved: one SSD failure, format failure

The SSD of msata interface in win7 system disk is out of order and can’t enter the operating system to boot. The hard disk is connected to the new machine. The format of the hard disk in win10 is shown as raw, which cannot be formatted. The disk is checked, and there is no error. The reconstruction boot record is invalid.

At present, the faults are as follows:
① for the deleted file that cannot be written, after the device is ejected, the machine is connected again and the display is restored, that is, the file cannot be deleted.
② Unable to format

③ the Diskpart clean command is invalid. Time viewer error prompt, unable to make the hard disk block zero


postscript: at present, the problem has not been solved, and the experienced readers are looking forward to your advice.

Windows can’t delete the file, indicating that it is in use. (release of document occupation)

Problem: when deleting a file, it prompts that the file is occupied.

Solution one: use 360 and other third-party software to release the occupation by fool.

Solution 2: use task manager.

Why not use the fool method?I need to delete the problem file on the server. It’s impossible to install 360 on the server! What should I do?

Open the task manager – & gt; switch to CPU – & gt; search the absolute path of the file to be deleted in the CPU’s associated handle, as shown in the figure, doc file and PDF file are occupied, and the process ends. The file is occupied by contact.

Authentication error occurred on remote connection, the required function is not supported

Foreword: when connecting to the server remotely, there is a remote connection error. The required function is not supported.

Official document: credssp update of cve-2018-0886
remote command: Win + r => mstsc

Solution 1: configure the local machine’s group policy.

gpedit.msc -≫ computer configuration – & gt; management template – & gt; system – & gt; credential assignment – & gt; encryption Oracle fix – & gt; start the policy and configure it as “vulnerable”.

Figure 2.2

Solution 2: modify the remote connection settings of the remote machine.

Setting the properties of the remote machine to unsafe. note: after the server changes the properties of “remote connection”, it needs to be restarted, which is troublesome. Solution one is recommended.

Postscript: the above is some personal experience, I hope to help readers, if there is a better solution, I hope you put forward valuable suggestions.

Record the location and cleaning of chrome junk files under appdata of Disk C

Background: the space of C disk is inexplicably red, and a series of soft armour cleaning are used, but there are still nearly 10GB garbage files missing

As shown in the figure:

after troubleshooting, it is found that the size of C: (user/appdata/local) is too large

This folder is related to the software data and cache installed on the system. It is easy to cause unexpected results if it is changed.
Can you refer to: what tool can effectively clean up the files in the directory “C: users: user name: appdata”?

Continue to drill down to the chrome folder

C:\Users\Administrator.USER-20190509ND\AppData\Local\Google\

Win10 starts infinite loop auto repair, and the repair fails

Background: since the last normal use a few hours ago, no software or patch has been installed. The only action: repair the network with Netsh command prompt, and then restart according to the prompt.

Phenomenon: after win10 starts, it prompts “diagnosing computer…” “Repairing…” , and then repair failure, dead loop. Up to the successful start, a total of 15 restarts.

Solution (failure):
1) according to the solutions of Baidu and Google, the advanced option is used to start, and the start fails.
2) after that, use the command prompt Bcdedit to turn off the automatic repair {UUID}, but it still fails.
3) security mode (with network) cannot be restarted.
4) there are still files on the desktop, which cannot be ghost, factory recovery, etc.
……

Solution (temporary success):
Advanced Options -> disable driver signature -> Restart successfully and enter the desktop.

PS:

    after restart, the device manager shows that all devices are in normal use (USB, NIC, etc.) after restart, because there is no blue screen, all minidump files are not captured, and specific errors cannot be analyzed. After restart, system32 -, logfiles -, SRT – srtTrail.txt The file indicates that the repair failed 15 times, but the error is not pointed out.

Svn warehouse migration in Windows Environment

Background: due to server changes, SVN warehouse needs to be migrated to a new server.
Environment: Windows Server 2008 R2

PS: attention, *. Vsvnbak backup file is only applicable to the backup and recovery of SVN server. SVN server cannot use this file when changing the host for resource migration!

The svnadmin command is used to backup and restore the warehouse to realize data migration.

1、 Source SVN server:
1. Download the console CD to the visualsvn server/bin directory
2. Execute svnadmin dump source warehouse address/Project & gt; destination backup folder/project name

For example:

If the command is executed successfully, you will see the console execute the backup command to back up all version history to the target file. If "access denied" is prompted, please check the access permission of the source warehouse folder and give the authorization

3. Manually copy the generated . Dump file to the target host

2、 Target host

1. Install the SVN server
2, console CD to the installation directory, svnadmin load target path/warehouse name & lt; . dump backup file
3. The backup recovery is successful, as shown in the figure below, you will see the file version

Event manager error: source distributedcom

Foreword: Windows 10. The event viewer frequently captures system errors and queries the cause.

Error:
using event viewer, the error is as follows:

Application specific permission settings are not granted to the user NT authority/local service Sid (s-1-5-19) in the address localhost (using LRPC) running in the application container's unavailable Sid (unavailable). For
CLSID is {d63b10c5-bb46-4990-a94f-e40b9d520160} , appid is {9ca88ee3-acb7-47c8-afc4-ab702511c276}
, local activation permission of COM server application. This security permission can be modified using the component services management tool.

Shortcut command:

Event Viewer: Win + R eventvwr.msc Device Manager: Win + R devmgmt.msc

Problem location:
when using vs to develop a. Net project, the project involves RPC, but the driver of the supporting hardware device is not installed in the local development environment. Therefore, when the program is compiled and started, the event viewer will report an error.

Problem analysis:

The problem belongs to the developer class, and has nothing to do with the windows operating system error. You can install the corresponding hardware driver by yourself.

Other similar solutions:

If windows 7, windows 10 and other operating system related, built-in programs report such errors, you can refer to the following tutorial for authorization solution.
