Use the System Restore tool to restore the affected computers back to a point before the problematic updates. To forestall issues with problematic updates, one needs to install and configure the Windows Server Update Services (WSUS) Server role.

Explanation:

Windows Update creates a restore point prior to applying any updates and this makes it easier to rollback any problematic updates using the aptly named System Restore utility. System Restore can be launched either from within Windows or during startup depending on whether the computer can be booted or not.

One solution to preventing this kind of problem is the implementation of a Windows Server role, the Windows Server Update Services (WSUS), which helps administrators to safely manage Windows Update for clients within its network. WSUS allows administrators to test updates for issues and approve them before they are available for deployment to clients.

Define a function below called process_grades. The function takes one argument: a list of integers. Each integer in the list cor

stealth61 [152]

Answer:

Following are the code in the Python Programming Language.

#define function

def process_grades(std_grades):

result = [] #list type variable

for grades in std_grades: #set for loop

if 90<=grades<=100: #set if statement

lettersGrade = 'A' #variable initialization

elif 80<=grades<=89: #set elif statement

lettersGrade = 'B' #variable initialization

elif 70<=grades<=79: #set elif statement

lettersGrade = 'C' #variable initialization

elif 60<=grades<=69: #set elif statement

lettersGrade = 'D' #variable initialization

else:

lettersGrade = 'F' #variable initialization

result.append(lettersGrade) #append the value of lettersGrade in result

return result #print the value of the variable result

print(process_grades([90, 85, 85, 72])) #call the function

Output:

['A', 'B', 'B', 'C']

Explanation:

Here, we define the function "process_grades" and pass an argument in the parameter list is "std_grades" in which we pass the grades of the students.

Then, we set the list data type variable "result" i9n which we store the grades of the students.

Then, we set the for loop and pass the condition.

Then, we set the "if-elif" statement and pass the conditions as given in the question.

Then, we append the value of the variable "lettersGrade" in the variable "result".

Finally, we call then function.
