To repair Bootloader, you should prepare a Windows 10 installation disc.

Step 1. Boot from Windows 10 installation disc and press any key to continue.

Step 2. Then navigate to Repair your computer->Troubleshoot->Advanced options->Command Prompt.

Step 3. Type diskpart in the command prompt.

Step 4. Type the following command and press Enter after each command.

•list disk

•sel disk 0 (where 0 stands for the boot drive)

•list vol (note which volume is the EFI partition, mine is 4)

•sel vol 4

•assign letter=N:

•exit

Step 5. Type N: (the drive letter you just assigned and hit Enter.)

Step 6. After you have assigned a drive letter Using Diskpart, you can format the EFI partition using the following command.

•format N: /FS:FAT32

Step 7. Now, type bcdboot C:\windows /s N: /f UEFI and hit Enter. This command will repair your Bootloader.

Then try the bootrec /fixboot command again, fixboot access denied in Windows 10 could be solved.

RUn cmd as admin:

Turn off the auto-disconnect feature

Windows will drop idle connections after a specified time-out period, I think it is 15 minutes by default, to prevent wasting resources. You can, however, easily re-establish the connection manually.

If you wish to turn off the auto-disconnect feature, type the following in an elevated command prompt and hit Enter.

net config server /autodisconnect:-1

Turn off auto-tuning network

If it occurs while copying large files over network drives, it could be due to the auto-tuning network.

To turn it off, open an elevated command prompt windows, type the following, and hit Enter:

netsh int tcp set global autotuninglevel=disabled

Go to Device Manager, network adapters and find the ethernet one.

– right click for properties – advanced 

Disable Energy efficient ethernet (and or green energy) and Wake on magic packet.

Registry Settings

These registry values must be created on the SMB gateway, which is specified in the repository settings as “Gateway server”. If the gateway is set to “automatic”, add these registry values to all Windows servers managed by Veeam Backup & Replication.

• NetUseShareAccess
  For Veeam B&R 8.0.0.917 or later, the following registry value allows Data Movers to open backup files by a resilient method similar to the Windows net use command.
   Key: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication\
  DWORD: NetUseShareAccess
  Value: 1
  Note: If credentials are required, specify Domain\User or Host\User in the repository settings. .\User credentials are not supported with NetUseShareAccess. For example, specify “NAS-01\Admin” instead of “.\Admin”.
   
• SessTimeout
  This increases the amount of time the Windows SMB client will wait for a response from an SMB server before it aborts the connection. The default timeout is one minute.
  Note: Reboot Required
   Key: HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters\
  DWORD: SessTimeout
  Value: 600
  Note:This is a value in seconds. Try a value of 600 decimal (10 minutes).
   
• TcpMaxDataRetransmissions
  This increases the number of times the Windows TCP implementation will retransmit a data segment before it aborts the connection.
  Note: Reboot Required
   Key: HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  DWORD: TcpMaxDataRetransmissions
  Value: 10 (Default: 5)

Prerequisites:
    Ensure the the target machine has PowerShell Remoting Enabled (as it's Disabled by default)

PS C:\Users\kimconnect\Desktop\Notes> Enable-PSRemoting -Force
WinRM has been updated to receive requests.
WinRM service type changed successfully.
WinRM service started.
WinRM has been updated for remote management.
WinRM firewall exception enabled.

Alternative method:
a. Get PSExec: https://docs.microsoft.com/en-us/sysinternals/downloads/psexec > extract copy contents into %windir% or "C:\Windows"

b. Run this command:
psexec \\hdqfswp001 reg add “HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters” /v SessTimeout /t REG_DWORD /d 3600 /f

---

Add this registry key to increase File Session Timeout:

$serverName="FILESERVER01"
Invoke-Command -ComputerName $serverName -ScriptBlock {reg add “HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters” /v SessTimeout /t REG_DWORD /d 3600 /f }

To Automatically Mount VHD or VHDX File on Startup in Windows 10,

1. Open Administrative Tools.
2. Click the Task Scheduler icon.
3. In the Task Scheduler library, click on the Create Task… link on the right.
4. In Create Task dialog, fill in the Name box some meaningful text like “Automount of my VHD Drive”.
5. Set the options as follows:
   – Configure for Windows 10.
   – Run whether user is logged on or not
   – Run with highest privileges box
6. Switch to the Triggers tab and click on the New… button.
7. Set the Begin the task option to At startup.
8. Select to the Actions tab, and click on the New button.
9. In the Program/script text box type powershell.exe.
10. Type the following in the Add arguments text box: Mount-VHD -Path "Full\path\to\your\VHD or VHDX\file". Change the Full\path\to\your\VHD or VHDX\file portion  to the actual full path of the VHD/VHDX file you want to have automatically mounted at startup.
11. Switch to the Conditions tab and disable the option Start the task only if the computer is on AC power.
12. Click on the OK button to create the task.
13. Type your user account password (or other administrative user account credentials).

You are done!

Notes:

• If your VHD file is encrypted with BitLocker, you may need to add a delay to make a credential prompt appear after you sign in to Windows. Enable the Delay task for option on the New Trigger page, or edit the existing trigger. 30 Seconds should be enough.
• You can disable this task to temporarily stop mounting your VHD/VHDX file at startup. You can re-enable it when needed.
• To permanently disable the VHD file auto-mount, delete your task under Administrative Tasks > Task Scheduler > Task Scheduler Library.

That’s it.

• You can enable the legacy SMB client to access network devices using SMBv1 protocol via the Control Panel (Control Panel -> Programs and Features -> Turn Windows features on or off -> SMB 1.0 / CIFS File Sharing Support -> SMB 1.0 / CIFS Client). In addition, you can access the features installation dialog by running the optionalfeatures.exe command.

• If you use anonymous access to connect NAS or other computers, you need to enable the insecure guest logon policy. In Windows 1803/1709 it blocks access to shared network folders over the SMB 2.0 protocol under an anonymous (guest) account. To do this, in the Windows 10 Local Policy Editor (gpedit.msc), enable the Enable insecure guest logons policy in the GPO section: Computer Configuration -> Administrative templates -> Network -> Lanman Workstation.

Windows 10 Consumer Experience adds tiles to the Start Menu for things like Candy Crush, Solitaire, and other non-business applications. There’s a simple way to disable this. Note that this does not remove any of the built-in apps like Calendar, Mail, or even Xbox.

Group Policy

The best and most practical way to disable this would be Group Policy. There’s a setting called “Turn off Microsoft consumer experiences” located at Computer Configuration > Administrative Templates > Windows Components > Cloud Content”. If you enable this policy, the extra stuff will go away.
