Recover the Deleted Items

If you don’t know what a Hex editor is, you probably shouldn’t be hex editing anything, but if you want to try, Google for “hex editor” – UltraEdit is probably the best and easiest one to use. Before doing anything to the PST with a Hex Editor, make a copy of the PST, or you may end up losing all of your e-mail.

1. Open the PST in the Hex editor.
2. Delete positions 7 through 13 with the spacebar. Since you’re using hexadecimal numbering, this actually clears 13 characters in the following positions:
   00007, 00008, 00009, 0000a, 0000b, 0000c, 0000d
   0000e, 0000f, 00010, 00011, 00012, 00013
   As you clear the characters, the editor displays the code “20” in their position.

1. Save the PST, it is now corrupted.
2. Run the Inbox Repair Tool, SCANPST.exe, to recover the file. Use Windows Search utility to find it. For additional information on the Inbox Repair Tool, see How to use Scanpst.exe to repair Outlook data files or KB 287497
3. The Inbox Repair Tool creates a backup and repairs the damage and recreates the PST.

Open the new PST in Outlook. The Deleted Items folder should now contain the deleted messages, unless Outlook has already deleted them for good by compacting the PST.

https://www.wintips.org/how-to-fix-svchost-exe-netsvcs-memory-leak-or-high-cpu-usage-problems

Svchost.exe is a generic and legitimate Windows process that loads several other critical services for proper Windows operation. But in several cases users are complaining that Svchost.exe is hogging their CPU or Memory  resources without obvious reasons e.g. at moments when the user doesn’t run any programs.

In many occasions, I have troubleshooted the Svchost.exe (netsvcs) problem by using different solutions to resolve the problem depending on each situation.

From my experience, the Svchost.exe high usage problems – in most cases – occur on computers that are infected by a virus or a malware program. In the rest of the cases, the Svchost.exe (netsvcs) high CPU or Memory leak problems, can be caused by a Windows Update, or by a full Event log file or by other programs or services that start many processes during their execution. In this tutorial you can find detailed instructions on how to troubleshoot and resolve memory leak or high CPU usage problems caused by svchost {Svchost.exe (netsvcs)}.

How to solve 100 % Svchost.exe (netsvcs) High Memory or CPU usage problems.

Solution 1. Scan your computer for viruses.

Many viruses or malicious programs can cause the svchost.exe high CPU/memory usage problem. So, before you continue to troubleshoot the Svchost.exe high CPU usage problem, use this Malware Scan and Removal Guide to check and remove viruses or/and malicious programs that may be running on your computer.

Solution 2. Find and Disable the service that causes the “svchost” high CPU usage problem.

Svchost.exe is a process that is needed by several services or programs in order for them to run. So, determine which service or program runs under the svchost.exe process and is hogging your system’s CPU and memory resources and then proceed to disable or totally uninstall that program (or service).

1. Press Ctlr+Alt+Del keys simultaneously and then open Task Manager.

2. At Processes tab, check the Show processes from all users checkbox.

3. Right-click on the high usage svchost.exe process and select Go to Service(s).

4. At services tab you should see several highlighted services that run under the svchost.exe process.

5. Now it ‘s time to find out which process is hogging CPU resources: To do that, you have two ways.

A) You can perform a sequentially search using Google (for all highlighted services) and see if the searched service is critical – or not – for your computer.

Or –

B) You can try to sequentially stop services (one by one) until CPU resources come back to normal. To stop a service temporary:

• Choose a service
• Right-click on it, and choose Stop Service.

6. After you have figured out the culprit service or program, then navigate to Services in Computer Management to disable that service (or totally remove the culprit program).

To disable a service on your computer permanently:
1. Simultaneously press Windows key + R  to open run command box.
2. In run command box, type: services.msc and press Enter.

3. At Services management window, right-click at the culprit service and choose Properties.

* Note:  Most of the time, the culprit service is the Windows Update Service.

4. Change the Startup type to Disabled, press OK and restart your computer.

Solution 3: Empty Event viewer log.

In some cases the svchost.exe high CPU (or high Memory) usage problem has to do with the large log files in Windows event viewer. So, another solution is to clear Event Viewer’s log. To do that:

1. Simultaneously press Windows key + R  to open run command box.

2. In run command box, type: eventvwr and press Enter.

3. At Event Viewer: Double-click to expand Windows Logs.

4. Right-click on Application and choose Clear Log.

5. Perform the same operation and clear the Security, Setup, and System log.

6. Restart your computer.

Solution 4: Troubleshoot Windows Updates problems.

In other computers, the svchost.exe high usage problem may occur when Windows searches for updates (in the background). In order to troubleshoot high CPU usage problems during Windows Update, perform the following steps.

Step 1. Force Windows to re-create an empty Windows Update Store folder.

The Windows Update Store folder (commonly known as “SoftwareDistribution” folder), is the location where Windows stores the downloaded updates. If this folder is corrupted, then you will face problems during Windows Update. So, first try to force Windows to re-create a new empty SoftwareDistribution folder. To do that:

1. Simultaneously press Windows key + R  to open run command box.

2. In run command box, type: services.msc and press Enter.

3. Search for Windows Update service, then right click on it and select Stop.

3. Navigate to “C:Windows” folder.

4. Delete * (or rename e.g. to “SoftwareDistributionOLD”) the “SoftwareDistribution” folder.

* Note: Upon restart, the next time the Windows Update checks for available updates, a new empty SoftwareDistribution folder will be created automatically by Windows to store updates.

5. Restart your computer and then try to check for updates.

6. If the “svchost” high CPU usage problem persists, continue to the next step.

Step 2. Run Windows Update Troubleshooter

1. Download Microsoft’s Windows Update Troubleshooter to your computer.

2. Run Windows Update Troubleshooter and press Accept at the first screen.

3. Select the Detect problems and apply the fixes for (Recommended) option.

4. Let the program to fix problems with Windows Update and then restart your computer.

5. Check for Updates again and if the svchost.exe high CPU usage problem persists continue to the next step.

Step 3. Install the latest version of Windows Update Agent.

1. Navigate to Windows Update Agent download site and download the appropriate package for your Windows edition and version.

2. Run WindowsUpdateAgent*.exe

3. Close all open programs and choose Next.

4. Choose Agree and press Next.

5. Let the installer finish the installation and then restart your computer.

Step 4. Install the critical Microsoft Security Bulletin MS13-097.

1. Navigate to https://technet.microsoft.com/library/security/ms13-097 and click at the appropriate Internet Explorer Cumulative Security Update (2898785) according to your Internet Explorer version and Windows Version.

2. At the next screen choose your IE’s (menu) language and choose Download.

3. Run “IE11_Windows*-KB289875*.exe” and follow the on screen instruction to install the update.

4. Restart your computer and check for updates again.

Step 5: Fix Windows Corrupted System files by using the System Update Readiness tool (aka “Deployment Image Servicing and Management” – DISM tool).

1. Navigate to System Update Readiness tool download site and download the DISM tool for your Windows edition and version. *

* Note: Windows 8 already contains the DISM tool and you don’t have to download anything. Just open an elevated command prompt and type: DISM.exe /Online /Cleanup-image /Restorehealth (Detailed instructions on how you can run DISM in Windows 8/8.1 can be found here)

2. Double click to install the downloaded file (e.g. Windows6.1-KB947821-v34-x86.msu).

3. When the installation is completed, restart your computer.

4. Force Windows to check for updates again and see if the svchost high usage problem still persists.

Thank you “Eddie”:

http://kcwebprogrammers.blogspot.com/2012/02/everest-number-of-users-that.html

I have a client for which I use the Everest SDK to connect to the Everest database from a web application.  Last week, we started getting this error on the site:

“The number of users that simultaneously access SDK cannot exceed the 25 user(s) for this license”

Essentially, all 25 allowable connections were used up, so my web pages couldn’t connect to do anything.  So none of the pages on the site that connected to Everest would work.

I thought that maybe I had a place in my code where I wasn’t closing a connection and the open connections had built up to 25.  The SDK has a Clear method to clear sessions, and can be accessed from the SDK object browser, so I figured I’d just go in there and clear some sessions.  The catch was that I couldn’t even log into the SDK object browser because there were no connections left to log in with.  We tried rebooting the Everest server, we tried rebooting the web server, but neither one cleared the sessions.

Finally we filed a support ticket.  After a couple days, we received this reply:

“I wanted to reach out to you to give you an update on your ticket.
