Problem:
Receiving the “TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts” error in event viewer for Event ID 4226? A limit was first imposed back in XP SP2, with a concurrent connection limit of ten different connections per one second. 

(Number of half open connections)

Although most users won’t notice a difference in network activity if it’s increased, there is a registry value that can be set to zero to disable the maximum number of connections allowed.

This would be helpful for anyone using a download manager or torrent program that allows many simultaneous connections at once.

Solution:


Open “regedit” and navigate to“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters.”

add a dword32 “EnableConnectionRateLimiting”set to “0” hex

run cmd as admin

C:\Windows\system32>sc stop “ClickToRunSvc”

How to fix USB flash, SD memory card, CD disc & Pen drive write-protected error?

We use removable storage devices a lot on a Windows computer, and some of you should at least once encounter the issue of the disk malfunction, which is mostly about “the disk is write protected”. When Windows starts to write protect your disk, for example, a SanDisk 4GB USB flash drive, you can no longer use it anymore until you remove the write protection. And the fix methods are as follows.

Method 1. diskpart command

Step 1. Open administrative Command Prompt.

Step 2. Type these commands one by one and press Enter key after each:

• diskpart
• list disk
• select disk # (# is the number of USB drive with which you’re getting the write-protected error and is plugged in)
• attributes disk clear readonly

Step 3. You may now close Command Prompt and re-plug the USB drive and check if the issue is resolved, by dragging a file to the drive or trying to format in Windows Disk Management or EaseUS Partition Master coming in the later part.

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Services\AppXSVC
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Services\ClipSVC
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Services\WSService

Change the “Start” REG_DWORD value from:
0x00000003 (3)
to
0x00000004 (4)
on each of those, then reboot.

Open Registry Editor. and navigate to the following Registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\MTCUVC

Next, in the right pane you will see a 32-bit DWORD value named EnableMtcUvc. In case you do not see it, create it. Its default value is 1. Change it to 0.

Open the Win+X menu, and click/tap on Command Prompt (Admin)

netsh advfirewall firewall set rule group=”Network Discovery” new enable=Yes
netsh advfirewall firewall set rule group=”File and Printer Sharing” new enable=Yes

1. From the computer you’d like to enable the admin share, click Start or Cortana and immediately type “cmd“. From the list of results, right-click Command Prompt and select Run as administrator.
2. Copy and paste the following command into the Command Prompt window and hit enter.

REG ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f

Copy the following code into notepad and save it as a .reg file then merge it.
