Windows 10: Protected Mode super slow after update to Windows 24H2

After updating from Windows 23H2 to Windows 24H2, opening files in protected mode is very slow. Note that no other changes have been made to the computer.For Microsoft 365 aka Office 365 latest version, using Excel, Word, or PowerPoint, when you open files in protected mode, it takes over a minute to open the file when it would previously be done in less than a second before the update to 24H2. If you don't open the file in protected mode, it also opens very quickly.Scanning the internet about this issue, people suggest reverting to a previous release of Office but I don't see anyone els

Super super super slow running Windows 10

I have a Samsung touch screen computer. I upgraded to Windows 10 a couple of months ago. I have Norton antivirus. A couple of weeks ago my computer started to run slow. I did a "go back to a known good date" reset. worked for a while. then started to slow
down. Now it takes over an hour from turning on computer to get to google web page. It works, but is super super slow. Do you have a suggestion to try so I dont lose my saved data. I have only got on set up (F8) once on many attempts. Thank you for any help.

 

windows 10 problems...super slow

Hi,

Thanks for posting your query to Microsoft forum. I will certainly help you with this.

Before reverting back to Windows 8.1 let’s try to follow these methods below which can help us resolving this issue.

Method 1: Perform System Maintenance troubleshooter.

I would suggest you to perform System Maintenance troubleshooter on the computer and check if it fixes the issue.

Please follow the steps to perform System maintenance check to improve performance of the computer:

• 
  Press Windows and X key together and select Control Panel.
  
• 
  Click on Troubleshooting.
  
• 
  Click on View all on the left side panel.
  
• 
  Click on System Maintenance and follow the onscreen instructions.
  

Method 2: Check in safe mode

Step 1: Check in Safe mode

Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started.

• Type settings in search and click on Settings.
• Click Update and recovery, and then tap or
  click Recovery.
• Under Advanced startup, tap or click Restart now.
• Once your PC restarts, on the Choose an option screen, tap or click
  Troubleshoot.
• If you don't see the Startup Settings option, tap or click advanced options.
• Tap or click Startup Settings.
• Tap or click Restart.
• On the Startup Settings screen, choose the Safe Mode.
• Sign in to your PC with a user account that has administrator rights.

You can restart the computer to put it back in
normal mode.

If the issue doesn’t occur in safe mode, follow step 2.

Step 2: Perform Clean Boot

Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

How to perform a “clean boot” in Windows

Refer to Windows 8.1 steps, as they are applicable to Windows 10.

Note: Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.

If this lets you log in, follow the steps below.

If the issue persists, follow method 3.

Method 3: Update drivers

Step1: I would like you to update the drivers of the computer.

Follow the steps below to update the graphics card drivers.

• Press Windows + X key on the keyboard
• Go to device manager
• Right-click your display/graphic/video and audio/sound/realtek
  drivers.
• Click Update Driver Software and then follow the steps in the wizard that appears.

Step 2: Check in compatibility mode.

Download the network adaptor drivers from manufacture's website for Windows 10, if there no drivers available for Windows 10, download the latest driver from the manufacturer’s website and try installing it in compatibility mode. Compatibility mode
runs the program using settings from a previous version of Windows.

Follow these steps to install the drivers in compatibility mode and check if that helps.

a. Download the driver from the manufacturer’s website.

b. Right-click on the driver setup file and click on ‘properties’.

c. Click on the ‘compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 8 operating system from the drop down menu and proceed with the installation.

d. Once this is done, restart the computer and check if the issue persists.

applies to Windows 10)

Method 4: SFC scan

I would suggest you to perform SFC scan and check if that helps. The
sfc/scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. It is a utility in Windows that allows users to scan for corruptions in Windows system files and restore
corrupted files.

Refer the link: Use the System File Checker tool to repair missing or corrupted
system files

However if you still wish to downgrade you can refer the steps below.

Please refer: Go back to your previous version of Windows
